Hello,

my wireless connection stalls after like 5 seconds once the downloading
performance passes around 600 KiB/sec. I noticed in dmesg the following:
| ipw2200: Firmware error detected.  Restarting.
I can't tell if this is a regression because my wireless was never that
fast. It still works perfectly with my other link that is capable of
about 230 KiB/sec.

In [1] you can see debug output generated by the ipw2200 module which
was loaded with debug=0x3fff on v2.6.24 mainline kernel and firmware
3.0. Both wireless links are WPA encrypted. iwconfig reports for that
interface:

| Mode:Managed  Frequency:2.422 GHz  Access Point:    
| Bit Rate:48 Mb/s   Tx-Power=20 dBm   Sensitivity=8/0  
| Retry limit:7   RTS thr:off   Fragment thr:off
| Encryption key: Security mode:open
| Power Management:off
| Link Quality=83/100  Signal level=-47 dBm  Noise level=-89 dBm
| Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
| Tx excessive retries:0  Invalid misc:0   Missed beacon:10

Regards,
Sebastian
