Hello,

For some reason my computer seems to periodically disconnect from the internet. I've tried a few things and cant figure out for the life of me what's going on.

To be clear, it's a full on disconnection. Streaming like Netflix, Hulu, and CrunchyRoll get interrupted. I get disconnected from Discord and any online game I might be playing.

I live with one other person who is connected to the same router/modem I am and they do not have the problem.

Here's what I've tried:
Purchased new ethernet cable
Purchased new NIC card
Changed ports on the router
Changed ports on the router to my roommates connection
Virus scan using Avast
Malwarebytes scan
CC cleaner scan and clean
Reset router/ modem combo
Rebooted router/modem combo

I am totally out of ideas for what else I could be looking for or trying to do to resolve this issue that seems to only happen to my computer.

Thanks for any assistance.

Does it automatically reconnect some time afterwards or do you have to restart Windows ? If it reconnects by itself, how long does an outage last ?

Easy thing to try - go to Control Panel > Device Manager and find the network adapter, right click and choose Update.

If Windows is extremely busy, networking can suffer. Go start your game and start Task Manager > Processes tab. Click on the CPU column header to sort the highest cpu program to the top. Maybe that program is hogging the cpu and causing problems. Either don't use it when running games or uninstall it.

Check your C drive to ensure that it has plenty of free space. Windows need empty space to create temp files and cache memory. Running low on drive C can cause very strange problems.

Go do a System Restore back to a date before this started happening. You might need to reinstall programs that were installed after this date.

It does auto reconnect, every time very quick, less than a minute or so.

In regards to the network adapter, This should be updated as I installed the latest drivers for my new NIC card. I'll definitely monitor the CPU usage and see how that goes. The C:\ drive is at roughly 59 gigs used 59 free, out of 120GB total on an SSD.

Worst comes to worst i'll try a total reformat as I don't have any system restore points that I know for sure actually worked. The issue has been going on for awhile, it's just become more annoying, now.


**EDIT**

Looks like CPU usage is around 15-20% when the internet disconnects.

When it disconnects, does the network icon change on the bottom right?

My inet provider 'Cox' (Socal, they have a monopoly & do not care) does this to me almost daily, my cox phone also. TV works most of thr time, it does not go through the modem.

So a problem with the ISP can be ruled out.
