Issues with Wi-Fi

My ThinBook with Debian is installed with latest updates given by you.

But it still faces issues with Wi-Fi.

Major issue being, laptop fails to show (and connect) any wi-fi networks available, after rebooting laptop from hibernation. I am forced to shut down and reboot again, after which all the wi-fi networks become suddenly visible (!) and then can connect over wi-fi.

What can be the problem and solution to it?

Thank you

This seems to be a bug, and I too have noticed a similar issue with Wifi.

Sorry, there is no immediate solution for this. I suggest you try using 'sleep' instead of hibernating, if that helps.

I will try to narrow down the issue and will look for a fix.

Will try sleep over hibernate.

But in sme random instances i now am facing issue when laptop is ON as well. Wi-Fi signals disappear at random and though other devices can see those connections, my ThinBook fails to even find these networks. The icon for wi-fi goes red with LAN symbol on it. What this might be due to? Any patch you have for that?

This could be a hardware issue, maybe with the power supply to radio(wifi) module, I request you to please raise a ticket with the RDP.

After long follow-ups finally a Hardware enginner of RDP visited today for addressing the issue. He tried replacing the motherboard and the Wi-Fi cable (Antenna i guess) as a solution to this. But the problem remained the same with newer hardware too. After waking up from hibernation, system failed to catch any WiFi signals. Thus concluding that there is not issue with hardware (hence the older/original motherboard was reinstalled).

Please look into addressing the WiFi issue. Is there any software solution on the way? May be there's some issue with power management modules of OS?

We are not facing this issue with sleep, the wifi resumes well after sleep.
The wifi, however, disappears sometimes after reboot(rarely though), for which, we don't have any fix.
