Hi all!

I've got an Acer Aspire S3-391-53314G52add ultrabook here, booting in 13 seconds to kubuntu from its 20GB onboard SSD. Sweet linux machine for those interested!

Trouble is, the Atheros AR5B22 WLAN (b/g/n) keeps crashing my Belkin F6D6230-4 v1000 router (firmware v. 1.00.15). Admittedly, it's a pretty flaky router, but this problem seems to be unique to this combination of computer and router - and indeed to Ubuntu on this computer, as Windows works fine, and some other distros (e.g. OpenSuSE 12.2) don't support the wireless at all.

The trouble occurs with both radios, in the 2.4 GHz and 5.2 GHz bands. After a slow connecting process (1-2 minutes) the connection works for 5-30 minutes, and then the router crashes and restarts, taking every connected user's internet with it.

All Belkin offers for this router is an unsupported beta firmware v. 1.00.19 that they tell people not to use. There isn't even a download of the original firmware, so if it is bad I won't have a way back. dd-wrt does not support this router.

Anyone familiar with this problem? Should I fix the wireless drivers or the router firmware?
