Resolved Question

Problem with 5GHz network band on my pc.

So a few days ago a windows "driver" update came with like 20ish driver updates. My wifi driver was one of them. Now for the past few days i have been experiencing some problems with the 5GHz network. The problems are that out of nowhere my pc disconnects from the 5GHz network and it just disappears from the list completely until computer is restarted or the driver is reinstalled/roll-backed/updated. I know that this is not problem with the internet itself because the 5GHz network still appears on the other devices with no problems at all. Also i'm not sure if the info is actually correct but i can still see some other 5GHz networks, except for mine.

I have tried reseting router and everything, but doesn't fix the problem. I've tried to rollback and update the driver again, but it hasn't helped. I also noticed that on one of the "network" drivers was disabled (it was this one Realtek Gaming GBE Family Controller) for some reason and (i enabled it) had the tickbox "let windows disable this to save power" ticked. I unticked that and thought that it would fix the problem. Couple hours later the problem still appeared.

Sometimes instead of restarting my pc i just connect to the 2.4GHz network and after some time the 5GHz network just appears again on the network list.

I have windows 10, and a stationary pc
My Wireless network adapter is called "Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC" if it helps in any way

I'd appreciate any help.

Most folk learn to disable Windows Driver Updates.

Microsoft is not where I get my drivers from. I get them from my device maker's web site most of the time.

You had a working driver so go back to that as Microsoft will send you for a loop if you encounter this issue.

That is what i did already.

Yea that is what i did as i stated that "until computer is restarted or the driver is reinstalled/roll-backed/updated." i tried to rollback the driver and that is what i have done currently. I thought it would fix the problem but it didn't. + i don't even see where you can specifically disable driver updates from windows.

You are still relying on Microsoft.

I too have seen rollback fail to get me back to the working driver.

As to the disable, I use google with a phrase like "Disable Windows 10 Driver Updates."

As to the driver, it's horrible I know but think back to XP days where you did the manual search at the maker's site for your driver. You install that.

Thank you. I've found the driver makers site and i'll download the driver and see if the problem still persists.

Glad you worked it out.

For your PC you may want to avoid any driver updates unless you are comfortable with doing this again.
