Hi All, As of about this week, my main pc started having some strange wifi issues. basically it would randomly disconnect, sometimes it would let me reconnect, othertimes it wouldnt let me reconnect till i rebooted the machines. when connecting it gets stuck for ages on configuring internet then just say connection disconnected. I have tried other wifi sources and experienced the same and have also tried configuring manual ip’s etc. to no success.
I switched to ethernet thinking it would at least resolve my issues, but etherent seems to be getting capped at 100mb, even though its operating on a 2.5gb nic, and a cable that works on other devices for 2.5gb. auto negotiation sets the speed to 100mb, if i manually set the speed to anything more then 100mb the connection works for about 30 seconds then drops and wont work till i drop it back to auto.
i dont recall updating or anything before the issue started happening but im guessing i must have and something bugged it is my only guess. i am using an amd 9800x3d on an msi b650m gaming plus mother board using the inbuilt wifi card and ethernet. i did also notice that my wireless keyboard and mouse would take about 30 seconds to start working once booted around the same time however this appears to have fixed it self after installing updates. any advice/things to test? my network gear is a unifi express 7 and unifi switch, they were working fine up till now and work fine on all other devices. Any advice would be appreciated.
Thanks for the reply Marel, Sadly the Wifi issue is still there, if anything its gotten worse as i cant even connect to my home wifi from my computer at the moment. wifi works fine on everything else.
Altough you are right, 100mb would be more then enough to saturate my home internet (gotta love australian NBN…) i operate a home truenas server and regularly do larger file transfers off and on it, so the 100mb connection over eth is quite frustrating when i my nas supports 10gb. as mentioned, the cable works fine when operating on other 2.5gbe devices operating on the same port on the switch. you raise a fair point on the bluetooth, ill try disabling it and see if it has any input. below is the output from the command you mentioned (i changed the SSID to be MyNetwork instead of the real one)

On your Ethernet: Did it work before on a higher speed? If not, still the most likely explanation cabling or the other side. Try connecting the cable to anything else then the unifi switch, does it then go to 1000 Mbps or 2500Mbps?
Can you tell how you did set the speed to anything more then 100mb. Likely you can also disable auto-negotiation that way.
You Wifi looks reasonably clean, let see what disabling Bluetooth gives. You could also consider moving Wifi completely to 5G, that is, to get rid of any channels in the range 1-14.
