Unable to connect to Specific wifi connection

General system Newbie
1

Recently I set up Endeavour OS. everything was working as expected after setup for sometime.

But now I am not able to connect to my home wifi setup (which was getting connected properly earlier). There are no changes in wifi / router setup. I tried reinstalling complete OS again but even after fresh install, it is not able to connect. even from live USB, I am not able to connect to network.

Though, I AM ABLE TO CONNECT TO MOBILE HOTSPOT. I am also able to connect using USB tethering..

I tried following https://wiki.archlinux.org/title/Wpa_supplicant document and I got:

Could not connect to wpa_supplicant: (nil) - re-trying

so I tried to follow https://wiki.archlinux.org/title/Network_configuration/Wireless#Wireless_management document. below is the result of ip link.

but my dmesg | grep firmware failed with below output. and dmesg | grep iwlwifi result is empty.

The way i understand it with mobile connections your wifi chip is not used, but everything is done by your mobile internet connection setup. The way you describe it, and taking into consideration this is really old hardware (from what I could tell) it looks like a failing wifi chip, but maybe someone chimes in and will have a solution for your problem .

6

This is my home wifi setup which is not getting connected correctly. IF you notice, wlan0 keeps on repeating these states :

If it is wifi chip problem, ideally I should not be able to connect with any other wifi network as well but that not the case. I am able to connect with other networks.

I was able to connect with this network as well initially after OS setup but after some time it just does not connect at all.

7

As a side thought, does it work if you restart the router?

8

tried it. no change. same result.

9

You say that the connection refusal occurs with your system, and a live media.

This should exclude the possibility of a borked config on your system if it happens with a live flash drive as well.

What system did you test? Could you download the latest ubuntu and try again (or if you can double-boot windows) and report back if Wifi connection is possible with a different system?

What is on the other end, the router or AP which you try to connect to? What settings does it have? Are certain old protocols like 802.11a/b rejected or allowed?

Also, the Arch wiki is aware of similar issues with your h/w: https://wiki.archlinux.org/title/Broadcom_wireless#Connection_is_unstable_with_some_routers
