WiFi problem after installing

So I just installed bazzite again. I was installing it before , and know that there were no issues, coz it was same WiFi, same legion go device. But today, I installed it from zero, did all the same steps. And I have some weird connection problems. Internet works, but not with everything. Cannot connect to the GitHub or Reddit for example, as well as Steam, which is weird and coz of that I cannot install os normally at all. Failed connection errors to anything when setting up Bazzite in Bazzite Portal. If I try to reboot the system, it just will stuck on the black screen or on the “Verifying installation” screen. Because it cannot connect to anything related and important. Other sites works, like YouTube or Facebook, Google as well. This is super weird and I have no idea what to do. I just installed Bazzite, second time, same .iso file, same everything. And whoops, could not be that easy, something wrong.
