As Michael said, I was the one that reported the behavior. My card was a BCM4318
in a Cardbus format running V5.2 of the openfwwf. The AP is a Linksys WRT54G V5
running standard firmware v1.02.6. A list of nearby AP's with channels and
strengths are as follows:

          Cell 01 - Address: 00:14:BF:85:49:FA
                    Channel:1
                    Frequency:2.412 GHz (Channel 1)
                    Quality=70/70  Signal level=-6 dBm
                    Encryption key:on  (WPA2)
                    ESSID:"lwfdjf_rad"
          Cell 02 - Address: 00:1B:11:5C:B0:83
                    Channel:1
                    Frequency:2.412 GHz (Channel 1)
                    Quality=25/70  Signal level=-85 dBm
                    Encryption key:on   (WEP)
                    ESSID:"Browns"
          Cell 03 - Address: 00:1A:70:46:BA:B1
                    Channel:11
                    Frequency:2.462 GHz (Channel 11)
                    Quality=42/70  Signal level=-68 dBm
                    Encryption key:on    (WEP)
                    ESSID:"Larry with space"
          Cell 04 - Address: 00:23:69:81:B7:D9
                    Channel:6
                    Frequency:2.437 GHz (Channel 6)
                    Quality=34/70  Signal level=-76 dBm
                    Encryption key:on    (WEP)
                    ESSID:"Hoover"
          Cell 05 - Address: 00:14:BF:0C:7E:14
                    Channel:6
                    Frequency:2.437 GHz (Channel 6)
                    Quality=28/70  Signal level=-82 dBm
                    Encryption key:on     (WPA)
                    ESSID:"linksys"
          Cell 06 - Address: 00:22:6B:78:18:7D
                    Channel:11
                    Frequency:2.462 GHz (Channel 11)
                    Quality=26/70  Signal level=-84 dBm
                    Encryption key:on     (WPA)
                    ESSID:"Go Away"

I was connected to the AP in Cell 01. The test was my usual with a repeating
tcpperf run in one terminal and a flood ping to the same server in a second.
Please let me know if I missed any useful information.

This condition may take a long time to show up. For instance, my latest test ran
for 25 hours before failure. All other tests have failed much more quickly, but
one never knows. I have not seen this failure with standard firmware.
