Now that you say it... I'm having problems with wireless networking (wpi(4)) on my laptop, using WPA2. wpa_supplicant(9) frequently complains about disconnections/ reconnections, and TCP connections stall sometimes. I was suspecting aging hardware, but now I've checked "vmstat -m" and found a significant number of "calls to protocol drain routines". The kernel is from mid-december, but the problem has started to manifest at least some weeks before. With a wired (bge(4)) connection I don't see anything suspicious. best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
