Wireless driver for Lenovo laptops broken now?

I have a Lenovo Thinkpad x220 laptop with a "03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34)". In Fedora 16 it was partially working with my universities network: I had to set "options iwlwifi 11n_disable=1 ack_check=1" in the modprobe file and it would only connect sometimes (before this it didn't connect at all)

Did a complete fresh install of Fedora 17 Beta today with the same exact authentication settings and now I can't connect at all. Toying with the modprobe values doesn't do anything.

Is there anything I can do to get wireless at least somewhat working?

That part should use the iwlagn driver with no options.
Post the relevant lines from

lspici -nnk

Try going into BIOS, and disable the onboard LAN, and boot up again. I had to do this on my wife's Toshiba Satellite.
If I try to boot without the ETH line plugged in, the machine will not boot into a log in, at all.

Re: Wireless driver for Lenovo laptops broken now?

What authentication method does your university use? If it's EAP, and you're using a non-updated Beta install, you're probably hitting https://bugzilla.redhat.com/show_bug.cgi?id=802552 .

Try updating (over an ethernet connection, obviously...), or just install RC2/3 instead of Beta - http://dl.fedoraproject.org/pub/alt/stage/ .

Re: Wireless driver for Lenovo laptops broken now?

I'm sorry, I have forgotten about this topic

I've been running updates and I know a little while ago it just started working. No idea how or why, but I suspect it was related to that bug. Its working now, arguably better than it did in F16.

Thanks for the help!

Re: Wireless driver for Lenovo laptops broken now?

if the auth method is EAP, then yeah, that would make sense. We fixed it with an update.
