[SOLVED] linux >3.5.4 breaking wifi using rt2800usb

After upgrading to linux-3.5.4-1, I could no longer bring up the wlan0 interface. I returned to linux-3.5.3-1 and the problem was resolved. After installing 3.5.5-1, the problem has returned.

The wifi model is Buffalo WLI-UC-G300HP and it uses the rt2800usb module.

I'm going to reinstall 3.5.5-1 right now and save the error output so that I post it.

Re: [SOLVED] linux >3.5.4 breaking wifi using rt2800usb

This is the error I receive after trying to connect using wpa_supplicant.

rfkill: Cannot open RFKILL control device
Could not read interface wlan0 flags: No such device
WEXT: Could not set interface 'wlan0' UP
wlan0: Failed to initialize driver interface

This is the output of lsusb, showing the device itself is identified:

Bus 004 Device 002: ID 0411:0148 BUFFALO INC. (formerly MelCo., Inc.) WLI-UC-G300HP Wireless LAN Adapter

This is the output of lsmod, showing the the rt2800usb module is not loaded, nor does it load after running modprobe -v rt2800usb (even with verbose there is no output).

Well, now that I'm back to 3.5.3-1, I realize it may have been useful to run ifconfig wlan0 up, not just wpa_supplicant, but I'll wait for replies or other suggestions before I dive back in.

Thanks in advance.

Re: [SOLVED] linux >3.5.4 breaking wifi using rt2800usb

I figured it out. It was an error on my part, my fstab was out of date and mounting the wrong boot partition, so the updated kernel was saving to a location other than where I boot from. <speculation---> So I was booting the old kernel, but the new modules were in place and couldn't load because of version mismatch, hence no wifi.
