Internet Connection Drops After A Few Hours Until Reboot (SOLVED)

(1/7) > >>

DanTheTechMan:
Hello,

My Internet connection drops after a few hours and I have to restart to regain internet access. I am running Windows 7 SP1 64-Bit. I can access my router and local network fine but not the internet. I have my FIOS ONT box connected to my DD-WRT router, which is connected to a ethernet hub which connects all my devices to the internet (I strongly prefer to use wired connections wherever possible). As far as I can tell, it's just my desktop computer that disconnects. I have tried everything I can think of to resolve the issue, such as running various commands like ipconfig /release and ipconfig /renew, changing various settings on my router, running the NetAdapterRepair tool, and I even changed my security software from Bitdefender to Kaspersky, thinking that would solve it. Nothing I have tried works so far. The built in Windows troubleshooter doesn't help because Windows thinks I'm still connected. Does anyone have any ideas on how I can solve this dilemma? I have literally been losing sleep over this.

You could try going into Device Manager - click on View/Show hidden devices and expand Network adapters.

Right click on the Ethernet one and select Properties.

Under Power Management uncheck the box for Allow the computer to turn off this device to save power - OK

Under Advanced scroll down the dropdown and click on Wake on magic packet then change the value to Disabled - OK and close Device Manager.

If Internet works okay otherwise then I think the winsock and TCP/IP stack should be okay, but as a belt and braces, run a Command Prompt as an administrator and enter these cmds -

netsh reset winsock catalog

netsh int ip reset resetlog.txt

ipconfig /release

ipconfig /renew

ipconfig /flushdns

ipconfig /registerdns

shutdown /r /t 00

The last one will effect an immediate reboot to effect the cmds.

DanTheTechMan:
I've already tried all the above, and I still have the issue. 2-3 hours after booting my computer, without fail, my internet will cut out, and I will have to reboot to restore full connectivity. I'll try the commands again, however, I'm not too hopeful.

DanTheTechMan:
I tried running the above commands again, and I'm still having the same issue. I even uninstalled some software that I thought might be causing the issue. That didn't help. I'm typing this on my phone as my computer currently does not have internet. I'm at a loss as to what to do now. I don't want to have to restart my computer every 2-3 hours.

Boggin:
There's a couple of other things you could try.

In Device Manager scroll down that pane again until you see Receive side scaling.

Click on that and change the value to Disabled - OK

Right click on your WiFi icon or go into Control Panel and select Network and Sharing Centre - right click on the Ethernet adapter and select Properties and uncheck the box for TCP/IPv6 - OK and then see how the machine performs.
