RTL8723BE Wifi works for a few seconds then stops working [Ubuntu 24.04.1 LTS]

[allen-gxm]

First of all this : wireless info script output

When I boot into the OS, for about 10~30 seconds the WiFi shows me the available networks after that my WiFi stops working no internet. when I turn the WiFi off then on the visible networks category just spins forever without giving me any network to log into.

I am new to forums and stuff so, I don't know what all information to put in this post apart from the wireless info script output. Tell me and I will update it

Lets try disabling wifi power management and see if that fixes this

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
echo "options rtl8723be ips=N"|sudo tee /etc/modprobe.d/rtl8723be.conf

reboot

Thanks for your reply,
That seems to work, atleast for now
I will update my reply after some more time about 1~2 hour later

@jeremy31, It worked for about 3 minutes or so then suddenly disconnected and back to square one. stuck with WiFi searching for available network.

[jeremy31]

Did this happen with other kernels?

[allen-gxm]

I didn't used WiFi till now, I used to have Ethernet connection so i didn't really used WiFi.
To answer your question, I don't know.

[jeremy31]

I would like you to boot into an older kernel like 6.8.0-40 and see if the condition still exists

[allen-gxm]

Can you tell me how to do that? Is there any tutorial?
edit: nvm found it

[allen-gxm]

I tried 6.8.0 linux generic, 6.8.0-40 from ubuntu but anything below 6.8.0-41 is being wierd like half of the stuff on my menu goes even my ethernet so had to fall back to 6.8.0-41
i also tried 6.10.8 which worked just like 6.8.0-41 but no wifi still

Fix : I reseated my network adapter inside my laptop and its working, tho i completely removed ubuntu and installed arch.
