Wifi problem in ubuntu

[rushabh.runwal]

I just installed Ubuntu 20.04 onto my 10 year old laptop , so first worked perfectly fine , i was very pleased,
but then say 5 minutes after connecting my wifi (my mobile hotspot) i was getting problem with the wifi first it started showing the "?" on the wifi symbol and it when i tried reconnecting i got a error saying "Activation of network connection failed"
Rhis is happening every time i connect to wifi , i tried connecting to other hotstops,
What should i do i just cannot connect to internet in my laptop

EDIT: information about my wifi card :

$ lspci -nnk | grep -A2 0280

I had a similar issue with an earlier version of Ubuntu, I had to download the recommended drivers from the wireless card manufactures site. once they were installed I didn't have anymore issues.

I tried looking for more recent drivers but there seems to be non-available, you could either try to use a newer kernel by using the mainline tool or you could try this.

How do I get a Ralink RT3290 wireless card working?

I just installed Ubuntu 12.10 on an ASUS X401U, and after installation there is no list of wireless connections. I didn't have that problem with an installation on HP. What I can do to enable Wifi?...

Epic! We linked to the same solution

There is also this solution as discussed in the Mint forum. It involves changing a power configuration for the wifi driver. It's shown in the 10th post in the thread by a user named "antioch".

So i tried many things, got no luck then one day i turn off the "Wake by WLAN" setting in BIOS , because my ubuntu was rebooting sec after it gets shutdown, the rebooting problem remains
but my wifi is now working nicely...
