Classification: openSUSE

driver / firmware for Intel Centrino Wireless-N 2200 is basically useless. I
have to be extra careful "not to stress" the wireless network card too much,
otherwise it retaliates right away with "ieee80211 phy0: Hardware restart was
requested". I know it's also been declared by our colleagues from Fedora since
last year, but no real solution so far.

Reproducible: Always

Steps to Reproduce:
1. just establish any network connection that requires a constant stream of
data (tabs in browser with youtube films, torrent client, samba copy, on-line
radio in player etc.)
Actual Results:
no more network connectivity, although in KNetworkManager all looked fine. Plus
the dmesg result

Expected Results:
Wireless network connectivity should have stayed stable.
