The jetson keeps losing connectivity(ssh tunnel broken, docker push failure, loading a website takes ages). The wifi connection to the device(wifi symbol on the device) doesn’t seem to be disconnected during these periods. The signal strength is not an issue as my laptop is facing no such issues while being in the same area. But the jetson is showing extremely slow wifi speeds when it works (compared to my laptop on the same network)
The Jetpack version is 4.5.1
The Network Controller is Realtek Device c822
Please advise on how to debug this issue and what other information is needed to understand what is going wrong.
Successfully initialized wpa_supplicant
ctrl_iface exists and seems to be in use - cannot override it
Delete ‘/var/run/wpa_supplicant/wlan0’ manually if it is not used anymore
Failed to initialize control interface ‘/var/run/wpa_supplicant’.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

I followed this thread on fixing wifi issues for jetson nano but was not able to solve my issue.
I am facing issues in line with what this comment describes. But my speed drop is down to 100Kb/s or even lesser.
The issue had initially come up around a month ago. After that, I had reflashed the Jetson and everything was working fine for a week. But in recent weeks, it’s come up again.
Let me know if more information is needed, any help would be appreciated.
