• Lost internet connection - rogue app?

  Hi, I have downloaded a widget to toggle 3G last night and tried it out. It did not work so I uninstalled, but now I find that my phone is now more able to get an internet connection - it seemed have lost internet connection as soon as I typed on the widget.

  Is it possible that the app screwed up my phone this way, or is there another explanation (I'm trying to discover my carrier right now if the network declined - I can still send and receive text messages)?

  I have to reset my phone?

  Too bad. My career has simply returned internet settings on my phone and now it works again.

• New MacBook Pro lost internet connection

  Fortunately brought my MacBook Pro retina display 15 "and connected to a Dell monitor. (Hours of hassle, but I have another question/problem).

  After using it for a while, I lost my connection to my home network. But my older MacBook Pro 13 and my iMac 27 were still connected.

  I took the new MacBook Pro 15 "at the kitchen. And here, I got my connection again.

  So... WHY

  And... WHAT can I do to keep my internet/network connection when my new MacBook Pro 15 alongside other computers?

  AND... Is there a use for my Airport Extreme, when my DSL provides internet and network?

  No use of Airport Extreme is not mandatory

  I use Dlink router and modem and all the Apple stuff in our home works very well

  That said-

  Press Option - then click the WiFi icon and click the wireless diagnostic tests - the process of

  If nothing remarkable is found - let it run in the background as you go about your work

  Also, when you do this - take a screenshot of the gray information and post a photo

  Finally two points-

  1. you have indicated this is a new device - is there sufficient numbers DNS for the tour of your router?

  2. do you know if your router provides 2.4 GHz or 5 GHz of bandwidth?

• Problems with Win 7: lost internet connection and downloads

  Hello

  I'm not sure that the two problems are related... I don't know what topic to choose.

  I have a custom, with Win 7 machine, and I install all required updates. But for a while (months? I turn it off every night) it says 15 updates are available every time that I reboot, and I see no updates installed (I search for installed updates today).

  Anyway, let them go all the way, and when I restart, I have no connection. It's happened several times (everytime I reboot). Maybe that I had the chance to solve the problem by restarting (and reinstalling :)) 15 updates, but today I can't. I am connected by wire to a modem. Our all other computers work.

  I have a job in the process and need my internet connection (easier to work on a desktop computer with large screen of a laptop) and I can't.

  In network and sharing Center, there is a cross between 'Several networks' and the internet. I have the message if I 'connect or disconnect' "no Internet access.

  I did ipconfig, and I get media disconnected. I did not unplug anything!

  I would be very grateful for your help.

  Thank you very much

  Hi Allwyna,

  Thanks for the reply.

  As you said, there are 16 updates that never completed the installation. There could be opportunities updates are at the origin of the problem. So before solve us the connection problem. We should go ahead and first to solve the problem of updates.

  I would like to know you have installed any Security Antivirus software on your computer, if so I first suggest you temporarily disable the Antivirus software install on your computer and check if that helps.

  Warning: Antivirus software helps protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you have to temporarily disable it to install other software and/or any relevant issue, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks by malicious software.

  Try the methods.

  Method 1:

  I suggest following the steps listed in the article and check if it works.

• Lost internet connection of TZ205W

  I have a new TZ205W firewall, updated when installing to (I think) the SonicOS latest version 5.9.1.0 - 22o. The WAN port is connected at the border FIOS.

  After several hours of working properly, it loses its internet connection. At that time:

  • I can access is no longer remote,.
  • They no longer ping the WAN port,
  • He cannot ping internet addresses, and
  • I can't access the internet from the local network.

  However, I can ping it and connect to the administration of the LAN interface. As soon as I have it reboot, I again have access to the internet from the local network and can ping/access it remotely. Once it's down, it never comes back to the top unless it is rebooted.

  I have already tried these things:

  • Restarted "Current Firmware with factory default settings", and then he reconfigured the wizard and stick to the simple minimum configuration (i.e. leaving out my VPN and most of my NAT policies); It is exactly as I do for my several other TZ205Ws who work in other networks, except for the intellectual property-specific information.
  • Re-uploaded the same version of firmware, and then reset to factory default settings and it reconfigured as above.
  • Called the ISP to see if there was any possibility of a problem MTU, a conflict known between their unit and SonicWall, or maybe they could see certain types of traffic from the router that could make in being blocked on their side. But all they can tell me is that they see no unusual activity and not responsible for my router, only them that sits on the other public IP address on the same circuit. My other router provided by the ISP to another public IP address (connected to the same switch on the WAN side) doesn't lose connectivity when the SonicWall; However, this port is still upward if I can replace the firewall prior non-SonicWall serving this LAN, I got the new SonicWall.

  At its connection to the Wan is down, I don't see anything different on the device, so I am at a loss even know what diagnosis of the measures to be taken. Are there specific parameters and/or log files that might be useful to diagnose the problem? Is it possible that there is a problem with SonicOS version am I using? Pourrait - this point to a hardware router problem?

  Finally... an answer. In short, it was a known problem with the Alcatel FIOS in border Ontario here's the recap:

  Business of my client was sitting there in this situation with the border router and a Netgear FVS318 works correctly for perhaps three years. Then one day, we get more sophisticated and need a reliable VPN. So I happily order two SonicWall TZ205 units, which replaces the old Netgear. The SonicWall at the other end (cable internet service) works fine, but to do this, the border gateway refused to communicate with him, after six hours. A restart of SonicWall has solved the problem, but she returned after six hours. When he is down, I can still communicate with the border router that is on the same network with the ONTARIO Frontier and my SonicWall switch. So I know my port WAN on the SonicWall is not the problem.

  I have reset the SonicWall to factory specifications, ask questions on the forum of SonicWall, even to swap this SonicWall with one at the other end. I opened a call at the border. My research points the finger at ARP, but one of the level 1 technicians gives me this message of network technology: "This is not how it works." It was perhaps in hour four of my forty-hour ordeal. I consider allowing the ARP open via the diags hidden from the SonicWall page but reject the possibility because of the stern warning that this is not safe. (Sigh... anyway could have save me several hours).

  No change in this. I dig, dig, dig. I have activate gratuitous ARP. Finally, I discovered, by chance, while tinkering with ARP on the SonicWall, that a cache ARP Flush on my SonicWall solves the problem immediately. Now, how can that be? I ask Frontier. "It is your own router," they say, 'if we do not support. " I ask, "If my monitor package reveals that my router sends packets to the IP address and MAC address of your gateway and your entry door does not, whose fault is that?" They say 'Yours'! "Of course," I think, "and if my router did not meet your entry door, it would also be my fault." But what I'm saying is, 'I have to switch to Comcast to be able to use an advanced router." "It's your choice," said the Tech level 1 (the regional director had no one to happy to hear about it when I finally made an autonomous escalation by calling the line of business of complaint).

  In the meantime, a filtered to ARP packets monitor reveals that when I clear the cache ARP of SonicWall, there is something gratuitous ARP does not: it sends an ARP request explicitly to the IP address of the gateway. And this proves with certainty that it is not only related to ARP, but this is a problem on the side of the border. Yet, I can't speak with an NT. They tell me that their door is not in ONTARIO (which goes far to get rid of the smell of the true cause later).

  This is a site that is half an hour from my office, so Meanwhile, I activated a second NIC on a server at the office, given that the two default gateways and RDP server enabled on both so that I can RDP in via the border at the NIC2 server router, and then connect to the SonicWall via its interface LAN of NIC1 of the server do this without yet another trip into the office.

  At the same time, users in the Office tire repeated outages and ignore my instructions to call me when there is a power outage and unplug, plug back the power of the SonicWall while I'm trying to troubleshoot it. And, of course, it's my fault because I went from routers. So I withdraw my cheap Netis switch, connecting three WAN devices and replace it with Netgear switch a little better (but still not managed).

  In the meantime, however, I now put in more than 30 hours between all the swapping & resetting devices, the many trips in the office and maybe eight or nine calls to Frontier - none that ever made me an escalation to level 2. And all the time, I was insisting that someone there has been the answer already and just needed this person to I can have the five-minute conversation required. That's not to mention buying a for my router SonicWall support contract and a few hours on the phone with the support of SonicWall. And I can't exactly charge my client for all this time, since, according to them, it was my choice to switch routers.

  Then, suddenly and without apparent reason, my monitor package starts list null source ARP requests ever two minutes - explicitly directed against each of the five usable on the WAN subnet IP addresses. And they come from a MAC address address of the gateway in my ARP cache is not. I find the manufacturer of this MAC and see who is Alcatel. It is a time key, but it doesn't mean anything to me at the time. Of course, my SonicWall blocks these and hack attempts. I connect to the border router and put in place a firewall in the journal rule, but don't see anything. I guess that's because their router must not be able to record the ARP packets.

  More important still, however, my connection is more crashes after six hours. She stay up all night for the first time in 10 days. But the fact that things started working and there is no indication that a change had been made gives me no confidence that the problem has been resolved. Finally, I call the corporate number of the border and ask for the line of the complaint. Things happen in action. I get a call back from the regional manager in an hour. We exchange emails; I have him send a detailed explanation of the problem. He promises to get in touch with a network architect.

  But it will take some time, and I'm starting to wonder if it was the change of Netis in WAN Netgear switch that actually corrected it (even if not it is meaningless), so that night I put the rear Netis in place. But, like a dummy, I also disable regular gratuitous ARP and restart my router - so make three changes at once and ensure that I will have no idea who we intervene if things are going to come back down). This morning... it back down again, as before. And again, when I have emptied my ARP cache, I'm up. So I sink into the site at the beginning and move the Netgear switch in place and reactivate gratuitous ARP.

  An hour later, I get a call from one of the level 2 NT who worked on my case (via chat with level 1) early in the process. She says: "I went back to the case and was digging down through the chat logs. As soon as I saw ARP, I knew what the problem was, and I made the required change. "She explained that the Alcatel HAVE an option that should be activated when there are multiple WAN devices. In addition, my client's business is in the only place in the area where Alcatel terminals are still in use. Now at least I have someone who knows something and addressed to me, despite the fact that I was mean enough to buy my own router. None of the level 1 technicians I have met previously could even understand why - much less how - there could be more than one public IP address. One of them had even said, ' now you are chaining your router through ours, right? Nope. And maybe it's time this process 20 now-40 hours.

  Well, I have yet a full explanation why things started working at the same time I started to see the ARP requests from null which are supposed to be the cause of misfortunes, but I guess there is something different about six o'clock - on-demand and what I see now. The tech called me had no explanation why replace the network switch would have broken things.

  But he works right now and come about six hours since the last connection, so I should know shortly. Now I have the promise of a follow up directly from the Frontier network engineer and, above all, Frontier agreed to do without the Alcatel HAVE to an Ontario Calix - with which they have never seen issues ARP.

  And finally, now I know to search for "Alcatel" and "ARP" together on Google - and found all the specific answers that identify the question to the ONTARIO Alcatel in combination with class routers business. Maybe now I can get back to all of my other clients whose projects have been waiting the last week and a half.

  I'm sure that my life expectancy is just down by a couple of years.

  To begin troubleshooting you should provide some basic information about your configuration. How you have configured the virtual network (Bridged, NAT)? What is the result of ipconfig/all on the command-line of the customer? What is the host operating system? Have you tried temporarily disable AV and/or firewall?

• Internet Explorer lost the connection how to trouble shoot

  Windows 7, HP with amd memory chip.  Give me a lost internet connection message but I can't get any problem with laptop...  I'm confused

  Hi Lloyd,

  Your post is a little confusing: (!) You say that you get an interruption of the connection, but you are on anyway? Get the message, but are on a different computer on the same network and connection OK?

  I'm sorry, but could you explain a little more in detail what the problem is?  If you are on the same computer on the same network that you got this message, it simply means that there is a problem, but (of course) you can go back to that now. End of problem?

  Please answer with the information so I can help you.

  Kind regards

  I don't really know what the problem was.  I was getting an error message whenever I tried to log in using internet explore but could sign by using the Start button and the tab my favorites...  Finally, I rebooted the internet Explorer upgrade to 10 and now, I think that the problem is solved.  Thank you for your interest and sorry if my message was confusing, but obviously I was confused...

• XP mode no internet connectivity

  For reasons unknown, I suddenly lost internet connectivity in XP mode on my Windows 7 computer.  Connectivity is fine in Windows 7.  I tried many fixes and none have worked.  On some of them, I get that the network is unable to assign an IP address.  XP mode is configured correctly, but apparently something interferes with the internet connection that had previously been working very well.  I have a dual NIC card but change the card or the card settings did not work.  Then, I tried everything Basic that anyone anywhere has suggested.  I have to go out and buy a machine separate applications to work running XP because Microsoft supports so badly the XP mode?  PC manufacturer was not able to solve.  Work IS dept was not able to solve.  For me, there is clearly a network problem, but nobody can understand.  Integration features are enabled and all that stuff.  The router works fine.  I give up hope...

• CISCO RVO42 problems to connect to Internet and continues to give up internet connection

  I just bought for a new router in WAN VPN Cisco RV042 Duan (Small Business Series) Firmware version 4.0.08 - tm (released January 14, 2011). 1 WAN is configured to obtain an IP automatically add and 2 WAN is TRP with the username and password provided by our ISP. The two WAN configured for load balancing mode (auto). State of two WAN is connected, but most of the time only adds WAN 1 shows the WAN IP, DNS, etc. While WAN 2 Add sometimes shows WAN IP, DNS, etc, but most of the time 2 WAN is equal to zero all the. When this happened, I click on connect and sometimes it worked, but most of the time he cut it on the connection and everything will go back to zeros.

  1 WAN works too, but most of the time he gave up the connection to the ISP. I continue to live lost internet connection.

  I don't know what the problem is with my setups, the firmware or the router. Attached are snapshots of the basic configuration of the router.

  I'm disappointed because I thought when I bought this router that it can provide me with a more stable connection but after three days of usage, I have more difficulty to connect to the internet and my boss scolded me already. Help, please!

  

  

  

  

  Hello Gary,.

  My name is David Aguilar, and I'm a support with Cisco Small Business Support Center Engineer. Sorry you are having these problems. Several things:

  First of all, you will want to upgrade to the latest version of the firmware (version 4.1.1.01). It can be found here: http://www.cisco.com/cisco/software/release.html?mdfid=282414010&softwareid=282465789&release=4.1.1.01&relind=AVAILABLE&rellifecycle=&reltype=latest

  Second, if you use both WAN interfaces, you will need enable HTTPS protocol binding. If (encrypted) HTTPS traffic is distributed between the two WAN interfaces, it can cause instability when you browse to secure Web sites. To avoid this, you must direct all HTTPS traffic on a specific interface.

  To do this, go to system management > Dual WAN and select HTTPS as the service. Enter your LAN range as the IP source address and the 0.0.0.0 - 255.255.255.255 as the address IP of Destination. Simply bind HTTPS to the WAN 1 or 2 WAN.

  You can refer to the following screenshot:

  

  If you still have questions, please call us at the 1-866-606-1866. We are open 24/7 and would be happy to help you.

• My internet connection is lost at home after a few minutes. I re - turn on the wifi disabled, ten and it works again for a few minutes and then repeats. It works fine everywhere else?

  Relatively new MacBook OSX El Cap 11.4

  My internet connection is lost at home after a few minutes. I stop the wifi, then turn it back on and it works again for a few minutes and then repeats. It works fine everywhere else?

  Please see recommended settings of WiFi routers and access Apple points.

  Despite these recommendations, some routers will work better with the latest Mac models if you turn the radio 2.4 GHz mode in settings and only use the 5 GHz. Note, however, that very old devices Apple and some third-party devices can then not connect at all.

  Some third party routers have advanced that you may need to change the settings:

  The encryption algorithm must be AES.

  The group key interval must be 3200.

  I can't give you specific instructions on how to change these settings, because all routers are different. Refer to the documentation for the provider.

• Internet connection lost of Airport Express

  I have an Airport Extreme bought July 2013 connected to a modem cable my ISP, Cox. I use an iMac running El Capitan. An ethernet cable to connect the modem cable to the Airport Express Terminal. Lately I lost my internet connection. I have set using the diagnostics of the network in the preferences, network, which brings me to restart the cable modem. That works, but it can last all day, or just for a few hours, and then I lose the internet connection. I called Cox Tech support and the guy said that as long as my cable modem lights remained on the balance, then it must be a problem with Airport Extreme. It also suggests to connect the modem cable directly to the computer. I have already happened up to 14 hours at a time and have not lost the internet connection. This leads me to believe that the problem is with the Airport Extreme. I can do about it before buying another Airport Extreme? Thank you.

  What is the brand and model of the modem provided by Cox Internet? Is this the same modem that you use when you first installed AirPort Extreme? ... and, if so, it has had problems before connecting or just started to happen as shown in your post.

• Time Capsule has lost the Internet connection and DNS servers

  I use a Time Capsule for Time Machine via Ethernet backups for a couple of years, use it in mode bridge taking its Internet connection directly from my router and connected in turn by Ethernet to my iMac. (Most of the time that I also had wifi off on my iMac and took my Internet directly via the TC Ethernet connection.) A few months ago I upgraded to El Capitan, and the TC has lost its connection Internet (flashing yellow). A few days later I drove back to the Yosemite (for other reasons - Mail had gone mad) to restore a backup of the TC and everything was fine again for a few months. It may or may not be meaningful I plugged TC yesterday to new laptop for my wife to support for the first time, and this laptop is running El Capitan. Since then, the TC has once more lost its Internet connection and DNS settings and is stuck on flashing orange. By clicking on the 'Internet connection' status alert, tells me that the TC is not a valid IP address.

  

  I have reset the TC, repeatedly and reconfigured but all without success. After consulting the other discussions, I also tried giving the unit an alphanumeric name with no spaces & special characters and change the IPv6 "Link-local" configuration only, but this did not affect the result. And I updated the firmware for good measure. Then I unplugged overnight and carried out a full power cycle the steps recommended here, restart the router, TC and the computer (and performed a factory reset on the TC, while the router & computer was turned off). After doing that, the TC has become undetectable by AirPort Utility, until I have reset reconfigured once again, he and ended up in the same place.

  It may or may not be important to mention the following:

  1 when you set the TC after a reset, I repeatedly selected the option of adding to an existing network instead of create a network, but the installation wizard who ignored each time.

  2. in the installation each time, this point, I shows me the following, which seems to suggest that there is a problem but don't say so explicitly:

  

  I would be grateful for any advice.

  Weird how everything's going well for a few years and then crazy when you have something will change.

  El Capo adds some network problems more... but something could be fundamentally wrong with the installer.

  Your current configuration, it is apparently bridged but cannot get an IP address. The address 169.254 is give it since it's self generated.

  You need to do a manual installation. It simply means the Assistant is unable for any reason to be your network so start over and do it manually of misfortune (wow, or also possible misery, woah being where you are now!) to go...!

  1. I need to know what modem you are connected. Make and model please?

  2. the most important. What is the main router on your network or a modem?

  I gave the edge to make manual settings a few times. Somehow my instructions for Yosemite/El Capo got lost... I'll try and hunt down them. In the meantime, the basic method remains the same.
