New install and wifi is not working

[stevef]

Hello,

My wifi password uses WPA2 and my password has 24 numbers + one upper case letter + one lower case letter.  I will try to boot up with live version to see if the wifi works.  I checked the Show Password, so I saw exactly what I entered, and it was correct.  Very strange.

Thank you!
Tom

Tom,
Thank you, your answers to whether or not the wifi connected at the various possible stages of installation suggest the problem is apparent in any LL7.6, but testing with the live boot will confirm.  Let us know please.

Having a similar issue. As of right now, this issue occurs only when I connect to my home wifi router.

I've successfully connected to my phone's hotspot for Internet so I know it's not the hardware in my PC.

I'm using wpa_supplicant and NetworkManager. I tried swapping out wpa_supplicant with iwd since I have an Intel board, but that didn't fix the issue either. The issue may rest with NetworkManager.

I'm able to connect to my home wifi router with other devices such as my phone and various other windows computers. This pushes my next point.

Either this is some crazy mass anti-Linux Mac filter from ISPs or NM had a bad update. I'm convinced it's the latter. I experimented with changing the Mac address on my Linux PC and I was able to connect to my home wifi router for a bit until I changed something else. Now, whether I change the Mac address or not, the connection will not work.

I'll post some journal bits later, but most of the entries looked like blatant refusals to connect by the access points. Failure to complete 4-way handshake.

My wifi router supports the following:
2.4G band - WPA2 and down
5G band - WPA3-Transition and down
6G band - WPA3 (Personal only)

I just downgraded NetworkManager, and that seems to have fixed the issue. I don't know what happened with that, but NetworkManager may have been the culprit. I'll look through the diffs between the last couple weeks and let you know if they did anything major.

Thank you. It is a bit confusing because your post appears as a quote from TooShyTom which may be an error.  For clarity, it may be best to keep your input separate.
