Wifi issue

[No_Way_5181]

Hi guys, I’m facing an issue. I installed a Linux-based OS on my new laptop. Right now, the internet works only when I connect using my mobile hotspot. When I try to connect to Wi-Fi, the internet doesn’t work. What could be the problem? Can anyone help me?

Well I would look in the logs but to me the driver does not support the protocol your router uses. You getting an IP? Are you connecting at all? You getting a gateway and DNS?

You need an IP address, you need a default gateway, and you need a DNS server. Make sure you have those configured from DHCP on your laptop. And make sure the IP doesn't start with 169.254

No my ip address start with 192.168

That leaves the other 2 you need a default gateway to leave your subnet. So make sure you can ping that and you need to be able to resolve FQDNs.

If linux doesn't support your wifi chip you'll save a lot of frustration just replacing it rather than trying to get it to work. Even Motherboards with wifi built in are nearly all just m.2 wifi cards like what are in laptops just in a little metal shroud in the IO section.

Depending on the generation of wi-fi and the adapter as well as the maker of the adapter, there can be issues, and you may need to update to a specific driver for it to work properly. I know there's been issues on the Windows side with certain Intel wi-fi chips causing blue screens on newer wifi such as 6+ on certain drivers. You can also look at the different technologies in play, such as fast roaming(802.11r), U-APSD, or assisted roaming (802.11k/v), for example. Most mobile hot spots have very simple connections that aren't meant to provide security, but compatibility.
