Network connection keeps dying (about 1~2 times a day) and would require rebooting to reconnect?

Lunatique · Dec 12, 2016

My desktop computer's (Windows 10) developed this annoying problem in the last month or so. The network connection would just die, even though the taskbar icon shows it's still connected, and I would not be able to access any websites (except google websites like gmail, google search, youtube, etc., which is really strange), other computers on my home network, or even my router. To get reconnected, I would need to reboot the computer. This would happen on average once to twice a day, and it seems random and not at a set time.

I've searched the web for solutions and tried many of the common fixes found in forums and articles, but none of them worked. I even bought a USB 3.0 wireless adapter to see if using that would bypass the problem (I usually use wired ethernet connection), but it didn't matter if I was using a wired or wireless connection--it still happens.

This does not happen to any of the other computers in the house, so I know it's not the router.

While having to reboot the computer once or twice a day isn't a total nightmare or anything, it's just really annoying. I've tried all the fixes I could find the web, and nothing's worked (and I don't want to reinstall Windows or roll back to some previous state if I could help it).

Does anyone know what is happening and how I can fix it?

Well if you have not already done so.
For your Wired Lan port on the system, have a check via networking and sharing center of windows what speed and duplex setting the adapter is currently set to in speed value. 10Mbps, 100Mbps or 1Gbps.

If set to 1Gbps try setting the speed of the adapter to 100Mbps with a full duplex setting, manually selected.
And apply the new settings in windows 10.

For the wireless connection also check the properties in speed the adapter is capable of sending and receiving.
Then log into the router setup menu via your web browser you use.

If you find the router is broadcasting the wi-fi signal at a higher speed also lower it`s current set value.
Once again save the new changes made then exit the setup and configuration menus of the router.

Restart your system with windows 10 running on it.

In order to run a network speed via a wired cable of 10Mbps up to 100Mbps you should be using a Cat 5e rated cable from your system to the router to avoid any disconnection from the router or internet service it provides, as well as the home network setup.

For 1Gbps network speeds you must also use a network cable rated at Cat 6, 6e.

What router you using and how old ?

Shaun o :

The duplex setting was set to "auto negotiate." I've set it to 100Mbps as you suggested and will observer to see if that fixes the problem. I'll focus on that first and deal with the wireless next, since if the wired is fixed, I can return the USB wireless adapter (I just bought it very recently).

What I don't understand is why it only started to happen very recently, when it's never happened before in the last few years I've been using this exact same setup. I haven't changed anything to the system that might cause this.

I have a Netgear R7000 Nighthawk, so it's pretty new and a pretty good router.
