So you need to install the middleton bios, one of the things that (usually) does is to remove the wifi whitelist. It depends on the thinkpad model what the modded bios actually buys you, there is a table here.The thing that pisses me off about Thinkpads is that sometimes-often the Wifi chips are BIOS locked and can't be exchanged with an Intel M.2 card you get on Amazon.
Or just accept the slower wifi speed and plug in an ethernet cable, or get the docking station. I usually use my machines on cable network anyway.
Hmm, well you'd have to search around to see if anyone has written a custom bios for it. There's a pretty good hacking (in the good sense) community on thinkpads so there's probably a reasonable chance one has been made or will become available.Thanks for those links.
My T14s AMD has a wifi chip that even Windows 11 doesn't have a built-in driver forIt's not a speed issue.
