'cp' over NFS bails with a 'protocol not supported' error almost every time. 'scp' occasionaly fails with a 'MAC address corrupted'. This doesn't happen nearly as much as with NFS, but I presume there's some error-detection/correction in the SSH protocol. There are also random timeouts on a remote SSH-login and regular browsing/e-mailing also suffers from this. The above only happens when I have WEP (104bit) enabled. I have net/iwi-firmware-2.3_1 (the latest port) installed. >How-To-Repeat: Transfer a large file over NFS, using if_iwi and WEP enabled. >Fix: Disable WEP and the problems are gone. >Release-Note: >Audit-Trail: >Unformatted:
