When wifi turns on/connects to a network, monitor black screens for 3 seconds

I’ve noticed that on my desktop when the wireless card I have tries to connect to my wifi network, my monitor will black screen for a few seconds. This doesn’t happen when I’m connected via Ethernet.

Here are my comp specs with lspci:

00:00.0 Host bridge: Intel Corporation 8th Gen Core Processor Host Bridge/DRAM Registers (rev 0a)

This hasn’t started happening until the last six months and I should have reported it then, but I guess it wore me down. Anything I can do? Maybe try to uninstall/reinstall my wifi drivers? I’m not sure which ones to remove :frowning:

wpa_supplicant                          - WiFi authentication client and server
wireless-regdb                          - This package contains the wireless regulatory database used by all cfg80211 based Linux wireless drivers.
wireless-tools                          - Tools to configure wireless lan cards

I’m also seeing that my card keeps trying to connect over and over again to the same network. When it is connected, the speeds are about 0.16 Mbps, but all other machines on my network are getting 15-20 MBps. I’m connecting on 2.4GHz network for this tower.

Any help or insight would be appreciated!

To keep the original format of lspci you can put it in a code block. Example:

```

Has this always been happening or did it just start?

It could be faulty hardware. When the wifi card leaves it’s lower power state to do something it might be gobbling more amps than it’s supposed to or your motherboard/PSU may not be able to supply it properly which could volt drop whatever rail is also running your screen. Try another slot with it.

Some users have also had mixed results with the RTL8192EE

If you don’t mind me asking, which distro are you running? You may need to install some proprietary drivers.

Thanks! I edited the above so that it’s easier to read.

This started about 6 months ago, AFAIK. It’s not a USB, but actually plugged into the motherboard and it’s worked before :frowning: .

I’m running Solus and it’s worked under this distro before, as well as many other distros which I keep on this system like KDENeon and Fedora (Manjaro and Ubuntu previously).

I’m tempted to just start reinstalling drivers to see if anything helps, but I feel like I could be tempting fate.

I’d try a live USB of Ubuntu first, could give you some tip offs on how to proceed.
