If the card is an media/speed "auto-sensing" card, try disabling that feature and hard coding the settings in the card's flash memory (i.e. settings for 10BaseT vs. 10Base2, 10Mb vs. 100Mb, Half vs. Full duplex)...you may have to boot to dos and use the card manufacturer's setup disk. A shot in the dark, but I've seen similar problems with different operating systems... --Lee -----Original Message----- From: Panos GEVROS [mailto:P.Gevros@cs.ucl.ac.uk] Sent: Tuesday, September 22, 1998 11:03 AM To: Luigi Rizzo Cc: P.Gevros@cs.ucl.ac.uk; net@FreeBSD.ORG Subject: Re: network problem? Luigi, it is not a laptop, it is a PC, can this still be the case ? on what grounds it affects one machine and not another when it is on the same port -i tried moving it to another port and the behavior was the same, however the other machine (freebsd with same NIC) works fine in either port my latest finding : telnet/pings to it still freeze even when i kept a ping running from its console, stopping it and restarting and everything resumed..
