Running a Dell Thin Client that has the Intel chipset so using iwlwifi. I am also running kernel 6,6 as this is the latest kernel that lets you set the eeid for the monitors at boot as one of my monitors doesn’t get detected properly. Anyhow, I am using NM under KDE and all of a sudden I lost my internet speed as it went down to 200 KBps. I then used my phone as wifi hotspot and I went back to 200MBps. My computer is in the room about 7 feet from my router with nothing in between. I was surprised that 2G Hz would go to 200KBps making unusable. After a good half day messing with it. I figured 2G was the problem and hard set the channel to 5G Hz. Has anyone else seen this? Just happened out of the blue today while I was a on Zoom call which naturally ruined it.
You’re likely to run into trouble 
if you follow advice based on 
assumptions
because you haven’t provided enough 
information upfront 
.
Usually we do not discuss problems here, but solve them.
That’s why we always recommend deploying inxi -czv8 early on.
You also significantly improve your chances of getting a response
if you format your text neatly and
don’t present it as a “wall of text”
