  Hello

  ·        What type of Internet connection do you use?

  The 815 error code means that the network connection to broadband could not be established on your computer because the remote server is not responding.

  See the article mentioned below.

  Check with your provider for Internet services over DSL connections to make sure that you have configured it correctly.  Some require an additional network configuration until they are able to communicate.

   

  Step 1:

  Register a new user account that you are able to establish the connection. Follow the steps mentioned in the article below.

• HP 15-d018tu: sudden disconnection of internet connection

  I deal with these issues for a long time, my laptop suddenly drop wifi signals and not connet again.  He shows no more internet connection on my wifi router is. Kindly tell me what I can do.

  Hi @usman12345 ,

  Thank you for visiting the Forums HP's Support and welcome. I looked in your question about your 15 HP - Do1tu Notebook and have problems with wireless connections. Here is a link for the wireless connection troubleshooting.

  I would use the network of Windows 8 and resolution of the problems of the Internet section.

  I searched Microsoft for a fix for this and that they indicate on the forums that if you change the channel of the router on a different channel, that might solve the problem of connection of 5 GHz.

  You could disable IPV6 for the laptop. Some say this helps.

  Solve this problem Microsoft Fix it 50413 here is a linkto help as well.

  Hope it will be useful.

  Thank you.

• Internet connection suddenly disappeared after that Win 7 updated today

  Suddenly my Windows 7 computer has no internet.  Seems to coincide with a series of critical updates that were installed this morning.  Also, I can't do a restore for some reason any.

  The network icon shows the connection to my router and indicates that the connection has internet connectivity.

  I can ping my router, but not shoot to the top of its web page in a browser (IE 11, Chrome, Firefox all tried).  I can pull up other computers on the network.

  I can one of Google's servers to 74.125.224.72 ping, but cannot pull it up in a browser.

  When I boot in safe mode with network, the results are the same.

  NO request that goes to the internet, including IE, Outlook, update AVG, etc. can find something there.

  I tried the normal stuff: restart the router, PC.  Tried a restore point, but he failed.  Even if the PC is the router's IP, I did ipconfig / renew to release and rediscover IP.  I disabled the antivirus and firewall to see if it works.

  Any help?  Desperate, because I spent hours and depend on the work of the machine.

  Thank you.

• Sudden problem with internet connection

  I run Windows 7 on VM Ware Fusion 6.0.6 on an iMac 2, 66 GHz Intel Core 2 duo with OSX 10.9.5.

  Until 2 days ago, everything worked well with my Windows apps and the Internet connection.

  When I now try to use Internet explorer, Safari or any other application using internet I get the message "computer not connected to a network.

  To aid in the troubleshooting of Windows I get the message "network cable is not plugged in correctly or may be broken.

  I reconnected the cable on both sides - computer and router - without result. But it is of course not the source of the problem since the side my computer Apple clearly shows that I have an Ethernet connection and I have no problem to surf, mail or by using any other application via Internet.

  Can someone tell me how to restore my Internet on the side of Windows 7?

  Thanks for your help

  Try to reset the router and the modem, if you have other devices that work always reset the router and the modem. Then if the problem persists, run Use Mail connection doctor - Apple Support by fashion that apple provides.

• Pavilion HPE 150 t: I have a desktop Pavilion which does not connect to the internet all of a sudden

  Had two problems.  My AVG was locking up my computer with the function of guard dog.  I was able to get past and get uninstalled AVG.  Now, I can't the computer to connect to the internet.  I've updated the ethernet driver, but it still doesn't work.  Said that there is a problem with the driver.  I used a wireless adapter and it shows as connected but also says there is a problem with the driver.  I disabled all the security settings, that I can find.  Firewall AVG, Windows Defender, real key.  I did the sfc scan now and it found nothing.  He won't let me not reset the pc to restore the pc or anything like that.  I tried to update the BIOS, I think I already have, and he said that it is "denied" see administrator.  When I tried to reset the nsch he says he has been "denied".  I don't know what is blocking the connection.  Internet works anywhere in my house with the exception of this one computer.   Suggestions?

  So, I thought about it.  None of the support stuff helped but thanks for trying.  I'm always up for the Microsoft Security error at startup.  I noticed that I don't have McAfee installed when windows Defender popped up it asked McAfee, I used to have, and I saw where the real key is a McAfee product.  But I always felt that something is blocking the connection.  I ran AVG removal tool again, and once more he showed the AVG protection there.  I completed the deletion. still nothing.  I went to the properties of the ethernet and there I saw a place for the files AVG filter.  I unchecked it and BAM my internet connection was back up.  If not, was not windows.  This file kept loading with the drivers and I seen this every time but never uninstalled.  Once I killed him felt stupid, frustrated and angry.  I was very disappointed with AVG lately.

  Thank you for support for trying to help me, I learned a lot during this mess.

• Windows tells me there is an IP address conflict with another system on my network. It's wasting my internet connection. How should I do?

  Windows tells me there is an IP address conflict with another system on my network. It's ruining my internet connection, how to fix?

  1. Click the Start button
  2. Highlight connect to >
  3. Click Show all connections
  4. Right-click on the connection to the Local network
  5. Click on properties
  6. Click on Internet (TCP/IP) Protocol
  7. Click on properties

  Now look and see if obtain an IP address automatically is selected in the option button or if the use of the following IP address is checked.

  If the latter, you can change the last number of the IP address for anything else. Each window and then click OK.

  Example: It can be set to 192.168.1.1 and you want to change it to 192.168.1. 2.

  If it says still in use, then change to 3 and 4 and so on until there is no conflict.  Don't mess with any other numbers such as subnet mask, a default gateway or DNS servers.

  If the radio button is set to obtain an IP address automatically, then the problem is prolly with your DHCP server. Since I always assign my own IPs, I'm not sure what set which would result.

• Only https links work. Never installed security software. Never messed with the settings of internet connection. Refreshed Firefox. No joy.

  Firefox worked like a dream for as long as I got - until two days ago.
  It suddenly stopped linking to http sites. Still works for https sites, however.
  This problem does not exist in Safari (but I prefer Firefox!).

  Some dig and can already tell you that:
  (1) no additional security software have been installed.
  (2) no changes were made to internet connection settings.
  (3) connection Wifi is strong and fully functional (as it has always been)

• Internet connection Cox Cable & Airport Extreme

  I had the last three or four months a problem with Internet cable fall suddenly. All the lights on the modem cable have no problem with the modem. The Airport Extreme base station has a green light, as well. I have to keep resetting the modem cable 3 - 4 times a day. The ISP is Cox Cable.

  It affects all the iPhone, phone Android, iPad and other Apple computer, we have. All lose connectivity at the same time. If I connect to the Mac mini directly to the modem cable by the cable network the internet connection gets dropped without using the WiFi network.

  1 does anyone know conflicts between modems Motorola and Apple Airport Extreme networks?

  2. what else can I check or try to fix it?

  Airport Extreme: How would I test for a problem with the unit master of AE? The only thing I can think to do is reconfigure AE units and using one of the older AE devices as master and see if that makes a difference, but it's a headache to do if there is an easier way.

  Our WiFi network consists of a base station Airport Extreme 802.11ac with two base stations older AE acting as slaves to the base ac station to expand the network throughout the House. All base stations are running the latest firmware from Apple (7.7.3 & 7.6.4 on two more former slaves). The light remained green for disconnects. We have previously disabled IPv6 in Airport utility on the base station to avoid potential conflicts with the Cox' months before the start of this issue of network.

  Cable modem: Motorola MB 7420 - Cox says he could be the modem, so I bought a new modem cable Motorola MB7420 to replace the former Motorola cable modem - always have the same reduced connection problems. The cable modem shows any change in status or lights during connections has dropped, but only reset the cable modem seems to fix the problem. The two modems are not any lights/status change, but there is no internet connection, even if a computer is connected directly to the cable modem once the connection is released. I kept it connected and had it remove the connection to the internet again after resetting the modem (hours between the drops).

  I tried to connect a computer directly to the modem cable with a network cable and had the same problem, so I thought that I had deviated from the Airport Extreme base station as the problem. Now Cox claims that something came out last week, discussing the problems with Apple routers and cable modems or their network. I can't find anything, but they are supposed to send me information later.

  Coaxial connection: Cox is not finding any disconnection or time in their voting for our modem registers. We had three times to check the lines as he first seemed extremely windy Cox and had a problem before with problems connecting to the pole. Who was waived. They tested the connection between the pole and the cable modem, and we get a signal strong; some problems on the survey for our modem logs (every two hours). There is no water in the connections between the pole and the House. We have checked all the connections of the coaxial cable between the outer box and the cable modem. Cox is to revisit all connections around our House to see if they can find no evidence of a problem upstream or downstream from our part.

  Network cables: I replaced network between the cable modem and AE cables as well as AE to a computer next to him - no change.

  1 does anyone know conflicts between modems Motorola and Apple Airport Extreme networks?

  There are at least two known issues with Cox here on Apple's Support communities:

  1. Cox started the IPv6 role. The current workaround is to configure your AirPort base stations to use IPv6: link-local only.
  2. The series of Arris/Motorola SB61XX modem is incompatible with 802.11ac AirPort base stations (potentially, 802.11n models as well.) This is not bad in themselves, they just don't "play well" together. I have not heard of all reports on the series of MB74XX... so maybe it's not the question on this point.

  To test the incompatibility, check the ARP cache. It must contain only around a dozen entries. Considerably more could possibly indicate a problem.

  Run the network utility > Netstat tab > select the option "Display routing table information" > click Netstat

  Note: For OS X El Capitan, network utility can is located in Macintosh HD > system > library > Basic Services > Applications, OR via the Apple Menu > about this Mac... > system report > Tools menu of System Information > window > network utility

  To change the IPv6 configures your airport most convenient base stations you use AirPort Utility, as follows:

  From a Mac:

  • Run the AirPort Utility.
  • Select the base and then station, select change.
  • Select the Internet tab and then, select Internet Options...
  • Change the IPv6 configuration to: link-local only
  • Click on save and then click Update.
  • Allow the base station restart.
  • Do this for each of your base stations.

  Starting from an iOS device:

  • Tap the AirPort Utility to run it.
  • Select the base station.
  • Press Edit.
  • Tap advanced.
  • Tap on IPv6.
  • Change the IPv6 configuration to: link-local only
  • Type actually.

• Satellite C850 - no internet connection

  My C850 has decided this morning he went offline.
  It was fine last night, but now no internet!

  Checked the modem and internet connection is fine but keeps saying 'page unavailable' on Google Chrome.
  I tried Internet Explorer and nothing.

  Can get on the internet on anything else (phones, etc.)
  Don't have any idea why it suddenly did and indices?

  Probably I'm missing something really obvious!

  I guess that you are not able to connect to the internet via a LAN or WLan connection.
  Right?

  Check the settings of your anti-virus software or firewall security.
  This could be the reason of this problem in internet offline mode.

• L755 satellite internet connection drops but stilll connected to the network

  Hello

  I hope one of you can help me. I have a laptop 13 q Satellite L755 nice for a year and a half.

  My problem is that I surf the net and suddenly my internet connection drops down. On Firefox or IE, I have a message with a triangular signal yellow saying: "your connection has be revived."
  I'm still waiting on my network but I can't access the internet.

  The strangness, is that my family other PC or laptop have no problem on the connection.
  This happens on the wifi and cable. At home or other places of connection.
  In France and the United States. So my conclusion is that there is a problem with my laptop.

  I looked around some forums. It seems that some have a problem with IPv6.
  I have disabled the option to use IPv6 on my laptop, but I still have the problem.

  Another comment: I play the Kingdom of the fortress online.
  Sometimes I disconnect from this game but I can still surf the internet for a few minutes before undergoing a total disconnection.

  Looking forward for your help.

  As this happens using WLan and LAN its really hard to say why your connection is interrupted.
  Have you tested the internet connection with fresh preinstalled system?
  I mean it is possible that some software / updates received or installed in the past it would affect.

• Update Vista caused internet connection problems

  I have tried repairing computer of my sister, who says simply ceased to connect to the internet all of a sudden.  She said that began February 1... After looking through the system restore, I noticed there was an update installed on 31 January, so I restored the computer to the day prior to that, and now the internet works again.  Since then, I have disabled the automatic updates.  My question is: How can I solve this problem?  I can't leave just for always updates disabled...

  Hello
   
  Please can you us on the update that is causing this issue?
   
  This problem occurs especially if there is a conflict between the update and the application program on your computer, mainly the antivirus program.
   
  That's why I suggest to disable and re-enable the antivirus program or the security on your computer and try to update the verification of updates if the problem is resolved.
  Ensure that you re - activate the security on your computer program after a repair.
