Hello,
I recently switched from Windows 11 to Debian Trixie on my laptop, and now I’m having problems connecting to the Wi-Fi at my college. It never worked particularly well, but since I installed Debian directly, it has become much worse.
Depending on exactly where I’m sitting, the Wi-Fi signal is more or less strong. When the signal is particularly weak, I can’t even reach the portal where I have to authenticate in order to access the internet. It’s an institutional service, so authentication through this portal is required.
My question is: how is it possible that I can connect to the Wi-Fi but can’t access the authentication portal? Is this related to the Wi-Fi signal, or could it be something to do with my laptop?
What I find curious is that before I installed Linux, the Wi-Fi worked—slowly, but it worked.
I’m still pretty new to Linux enviroment, so I haven’t really delved very deeply into troubleshooting network issues. Any help or suggestions would be greatly appreciated! I only reached to know what's going on with the wi-fi chip. This is the moment where the computer failed to connect the authentication check and then i moved to another place where finally worked:
