iMac, loss of internet connection on sleep

I have remote on my iMac all the time. I have problems with it the loss of connection to the internet since the upgrade to Sierra. I connected to the internet via an Ethernet cable. I'll lose connection 10-15 minutes after leaving my computer and access it remotely. I "Wake for network WiFi access" checked and enable the display of SETTING for 10 minutes. " I just had this problem in the past few days since the upgrade. Any help would be greatly appreciated, I also use it for the presentation of work very frequently and lose the connection during their. Thank you

Not quite the same thing as I'm not trying to access remotely, but since the upgrade to Sierra, my iMac mid-2010 do not reconnect to the wifi in the morning.  It is not slow, it will not reconnect all until I explicitly select the network.  I don't have this problem before the Sierra, and it doesn't seem to affect my Air mid-2012 (also on the Sierra).

  • Windows Update 12/15/2010 causes a loss of internet connectivity

    After you perform the update 12-15 and rebooted the computer creates a loss of internet connectivity on our HP Pavilion (Windows 7). I confirmed this because I deleted updates and connectivity returns.

    While this loss of connection the network and sharing Center shows that it is connected to the network and to the internet.

    There were 10 updates total, for most updates of security, IE 8 1 update and an update of the malicious attack tool.

    I disabled updates automatic for the moment, however really puzzled by this and don't find any problems in the database about it.

    Ideas? Thank you!!

    Hi BillHarsh,

    You can manually download and install the updates one by one from the Microsoft Download Center & check if the problem persists.

    Hello

    Updates KB2478658 and KB2518864 cannot be installed in my SBS 2003 and caused a loss of internet connectivity.

    A while ago, I had a similar problem, i.e. do not install and loss of internet connectivity after you apply Windows Server 2003 SP2 on SBS. In this case, we have solved the problem with the support of a Customer Support person Microsoft, a service through which we paid.

    According to the suggestions that I found in the Microsoft Web sites, I managed to remove everything that was installed by the KB2478658 and KB2518864 updates and the reinstalled successfully. I did these manually because I don't have an internet connection.

    After you have reinstalled the above mentioned security updates, I repeated all the steps that led to the problem of the previous time. Among the steps taken, have been indicated in:

    Unfortunately, I was unable to restore connectivity to the internet this time.

    There is connection between the NETWORK card and router. I could ping the NIC IP address, but not that of the router (I get an "unreachable" message).

    I have a very serious problem, started only last Monday, I was using my laptop to last more than three years and having a problem just last week about the loss of internet connection after an hour or two after restarting the laptop.

I have a very important session the game and on Fri and it will be very costly if I can't then I would like to be back to normal as soon as POSSIBLE.

    I have a desktop running Windows 7 PC.  I recently had problems with loss of internet connection.  When I have trouble Shooting, told me that impossible to find a driver.  The adapter does not appear in Device Manager.  Help!

    Hello

    Definitely looks like a problem with the network device. Check with sound
    Support, their books online, the drivers and ask in their forums (if any)
    on known problems. If there is a control of the device shipped with the system
    Manufacturer (manufacturer of motherboard for customized systems). If a device check separated
    with the support of its creator and other resources.

    You could also remove or disable the device and try a new add-on as one
    new card or device USD. None of those who are dear.

    I hope this helps.

  • Anyone else experiencing the random loss of internet connection while using character animator?

    I seem to have a random loss of internet connection when performing character animator.

    Look into this further. It seems not related to the animation of character since today, it seems to happen randomly when running a simple browser. I think that maybe it's just my old router is about to die. I deleted my DNS cache and renewed my IP address and reset my router, so I hope that's all it took. Otherwise, it may be time for a new router.

  • Connect a HP OfficeJet Pro 8500 to router Netgear N600 loss of internet connection.

    Whenever the OfficeJet printer is connected to one of the ethernet to a Netgear N600 router ports, the internet connection is lost. Internet works without any complications, if the printer is not connected to the network. As soon as the ethernet cable from the printer is connected to the router (or a network switch) the internet connection is lost. If I look at the devices using the Netgear browser interface, everything seems appropriate. The printer uses DHCP and you will receive various IP addresses according to what remains is connected (e.g. 192.168.1.3). I've narrowed the problem to the printer, causing the loss of connectivity internet thie. Attach only my computer to the router (may be an iMac or a Windows XP system), internet works fine, plug the printer results in a loss of interest. Printer works fine and the documents can be printed after you connect to one of the ethernet ports.

    I tried to set a static IP address on the printer (e.g. 192.168.1.100) so that the attribution of a static address with the interface of Netgear using the MAC address of the printer - no approach fixes the problem. Netgear support is perplexed (they have even sent a replacement router, thinking it was defectiive, the two routers show the same problem). I have reset the printer to its default settings in order to eliminate potential conflicts with modified parameters. I also tried to change the speed of the link to something else than "Automatic", nothing seems to work.

    We will define an external static IP and DNS address for the printer.  I think that the external DNS will do the trick.

    -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
    -Enter the IP address in a browser to reveal the internal settings of the printer.
    -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
    -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') 250
    -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
    -Enter the IP of your router (on the Page of the Network Config) for the gateway.
    -Enter for the first DNS 8.8.8.8 and 8.8.4.4 for second DNS. It's Google DNS. You can choose a different external DNS if you wish.
    -Click 'apply '.

    Now, stop the router and printer, start the router, wait, and then start printing.

  • iMac loses the internet connection when I turn off wifi

    Any help appreciated! I'm not very computer savy! Can my grandson tell me (how) on some things.

    I lose the internet connection when wifi is disabled. It will happen when using any browser, Firefox-Safari-Google Chrome.

    Desktop computer is connected to the modem.

    Model name: iMac

    Processor name: Intel Core i7

    Processor speed: 3.4 GHz

    Number of processors: 1

    Total number of Cores: 4

    (By heart) L2 Cache: 256 KB

    L3 Cache: 8 MB

    Memory: 4 GB

    Any ideas? Thank you

    You can use an ethernet cable between the modem (= the internet connector) and the iMac.

    WiFi is like an invisible computer thread worms (among others) the modem. When you switch WiFi off, your computer cannot reach the modem and so there is no internet on your computer.

  • Lose internet connect during sleep

    Each computer or laptop I've owned kept his internet connection when it is entered in the mode 'sleep'.  When I woke up the computers I always had the internet always there.

    When I bought my new Acer Veriton X4620G a year or two ago the first thing I noticed was that whenever I wake the computer from sleep mode after that I left it for a while, his internet connection would be gone.  This would force me to click on the internet icon in the taskbar to log in again.  This issue has continued to this day.

    Can someone tell me how I can get my Acer Veriton to keep its connection to the internet when it starts in mode 'sleep'?  It's Aussie a nuisance having to click on the network icon and wait that he reconnect every time.  No cell phones my wife or my own laptop or any othe computer I've had that.

    Why is - what happens with my Veriton?

    Thank you.

    The only thing that works for me leaving my e-mail client and my browser open.  When I wake the computer from sleep mode after an absence of the connection is still there.

  • Loss of internet connection

    I use a wireless adapter wg111t. Intermittently, my connection completely disappears and I have to turn off and restart. The loss of connection is accompanied by the mouse cursor (mouse Microsoft Wireless) gel, generally with the pointer to highlight text, then after about 30 seconds, that it thaws, but not internet connection and the adapter could also well be installed because it does not appear in Control Panel. I have the adapter plugged into USB port high speed, the adapter flashes but the light on the USB port for the USb port relevsant is released when the connection is lost. I checked if there are IRS conflicted and can't find anything, I will also be changed to a different mouse and still have the same problem.

    Hello

    ·         The question is limited to Internet Explorer?

    Try the methods provided below and see if they help to resolve the issue.

    Method 1:

    Step 1:

    I suggest boot mode safe mode with network and check if the problem persists.

    Networking in safe mode starts Windows in safe mode and includes the network drivers and services needed to access the Internet or other computers on your network.

    The Advanced Boot Options screen lets you start Windows in advanced troubleshooting mode. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

    See the link below for more details:

    Startup options (including safe mode)

    http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

    Step 2:

    If the problem persists in Mode safe mode with networking, you can perform the clean boot on the system and solve the problem.

    Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

    See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

  • Loss of Internet connection and Windows 7

    In our headquarters, we have a desktop system running Windows 7, but also an iMac.  The two are connected to Apple's Time Capsule, which serves as a router and a backup for the iMac hard drive. (our Internet connection is cable Internet, by the way.)

    Since upgrading from Windows Vista to Windows 7, the Windows 7 Desktop faces of frequent Internet connection errors.  Generally, it loses the connection to the Internet several times per day.

    Today, it's the worst event we've seen so far (since the upgrade to Windows 7 last week).  We usually only an Internet connection for about 2-3 minutes, then it is lost and needs to be repaired.

    We enter the control panel > network and sharing Center > issues > Internet connections

    Let us Windows 7 automatically diagnose and repair the problem.

    Whenever he goes through the stages of diagnosis and repair, it ends by "reset the connection area card."

    At the end of the process - after everything has been repaired - we get the following report:

    "Default gateway is not available - fixed.

    Should what measures we take to permanently solve this problem?

    Moreover, the iMac does NOT have Internet connection issues whatsoever.

    Thanks in advance!

    I don't know what you use to assign addresses, so I guess it's a router of some sort. You will need to go to the website of manufacturers, look at the manual and know how to limit the DHCP address field. I changed mine to limit the address 192.168.1.200 thanks 192.168.1.250 DHCP assignment. Your router can use the 10. subnet, so your address may be different, depends on the manufacturer of the router, or if you use a DHCP, the scope with the DHCP server. Gives me 50 IP addresses for all the guests who may want to use wired or wireless connections and should be more than enough. This allows me to attributed to the 192.168.1.1 through 192.168.1.199 a device and not having to worry about the DHCP server, you try to use one that is applied continuously to a device (printer, switch, PC, server, virtual server, etc.).

    Once this configuration of your router, you will now need to assign a static ip address to your PC. All this is done for the network card.

    On the start menu:
    Control Panel
    Network and Internet
    Network and sharing Center
    In the right pane of network and sharing Center
    Change the settings of the card
    Double-click your network adapter
    Check the box «Détails»
    Note the following lines:
    Connection specific DNS (may or may not exist, depends on the provider)
    IPv4 subnet
    IPv4 default gateway
    IPv4 DNS servers

    Once you have written those down, you can close this box.
    You should be back at the "Local Area Connection Status" box.
    Select the option "Properties".
    Select 'Internet Protocol version 4 (TCP/IPv4)', which will be in a blue when selected.
    Now, select the option "Properties".
    "IP version 4 (TCP/IPv4) properties" box should have popped up. If so:
    Select the following text:
    "Use following IP address".
    In the IP address box, enter an IP address. Example: 192.168.1.20
    Press the tab, the subnet must fill automatically, otherwise, enter the "Subnet IPv4" value you noted in the above step. Examp, e: 255.255.255.0
    The bridge of dafult, enter the value of the above procedure. Example: 192.168.1.254

    Now switch to the next 2 boxes, DNS servers. You can have only 1 entry in DNS server of the DNS entry you noted from above.
    Enter the DNS servers that you noted above.

    If there is "Connection specific DNS" writing or entries, follow these steps (otherwise, skip the sections "Connection DNS"):
    Select the option "Advanced".
    The "Additional TCP/IP parameters" window should open
    Select the "DNS" tab

    If it has more than 1 input "Connection specific DNS", follow these steps:
    Select it "add DNS suffixes (in order):
    Select "Add..." »
    In the "suffix domain', enter the first connection specific DNS entry.
    Select the option 'Add '.
    Add all the specific DNS suffixes that you noted. You can enter one at a time.
    When the radio button finished choose "OK".

    If you have only 1 entry in "Connection specific DNS":
    Entitled "DNS suffix for this connection", enter the entry you noted above for the "specific" connection DNS
    When the radio button finished choose "OK".

    Check the "validate their output parameters.

    Select the radio button 'OK '.

    Select the radio button "close".

    You should see the "Windows Network Diagnostics' open and check for any problems. I hope that everything is fine and he says 'Troubleshooting couldn't identify the problem' and choose 'Close the Troubleshooter'.
    Close additional boxes or pop-ups that are open and check and make the connection sure allis. If not, go back and check all the steps. the most common are the IP addresses and gateways.

    Good luck. After back if it solves the problem.

  • Time Capsule or airport repeatedly loss of internet connection

    Greetings,

    Last month, I had a problem with my Apple Time Capsule and my cable company router intermittently lose Internet several times a day between.  This has happened several times a day.  My Time Capsule, Airport utility would show a 'green' status, but the status of 'Internet' is yellow.  It would resolve itself after several minutes, or if I rebooted the time Capsule.

    I did some troubleshooting and here's what I've been able to determine:

    • My internet business is the spectre of the Charter, and I use a Modem Arris.  The lights on the modem showed upstream internet connection was good, and technical support of the Charter stated that it was not a problem between the servers and the modem.  So, this seems to be a problem with the connection between the modem and the time Capsule.
    • Digging in the settings of the time Capsule, I noted that at one point defaults under the utility Airport-> Internet-> Internet Options-> "Configure IPv6" on the Time Capsule has changed its 'Link-Local only' to 'automatically '.  I am not sure when this change happened, but maybe with Time Capsule 7.7.3, firmware which I installed it right around the time the problems started.
    • I changed the IPv6 of Time Capsule settings go back to the "link-Local only" and since then have not lost to the Internet once

    So it seems to be an incompatibility between the IPv6 to my ISP configuration and configure IPv6 'automatically' on the Apple Time Capsule.  At this point the IPv4 and IPv6 protocols are still supported in the internet, but once IPv4 disappears at some point in the future I'll have to change the settings.  I hope that by then an update of the firmware from Apple or the modem from my ISP will fix this incompatibility.

    Hope this is useful to someone else!

    There is a document with settings for routers airport Apple on IPv6 with Comcast... I know that it works with TWC and it will probably also work with the Charter.

    http://mydeviceinfo.Xfinity.com/download.php?file_id=35

    There will be problems with dentition with IPv6 for awhile... Cox is the principal who is problematic at the moment and there are a number of positions that have also recommended parameters.

    IPv6 can also work if you use IPv4 dns servers of google... So the same instructions as the above document, but just simply replace the ISP DNS with values of google.

    Your Arris modem can also be a problem... We have noted problems with the model AC AE and TC WAN port with a number of modems... It's completely outside the issue of IPv6.
