T500 gives only 100 Mb wired connection; not 1 Gb

[DavidS]

I can only get a 100 Mbps wired connection (not 1 Gbps) on my T500.  I am connecting to a Netgear GS605 switch.  I have tried using exactly the same port and cable that gives 1 Gbps on another computer (a Dell XPS 420) but the T500 will still only connect at 100 Mbps.  Both computers are running Vista Ultimate.  I have tried changing the Advanced/Link Speed & Duplex setting (in the Intel 82567LM device driver) from Auto Negotiatitation to  1.0 Gbps Full Duplex but this does not help.  Any suggestions?

have you tested transfer speeds to see if it's simply misreporting your connection protocol?   i've found more than one system reporting 100 Mbps yet transferring anywhere from 75 MBps to 105 MBps (.6 Gbps to .84 Gbps).

also, have you turned off wireless on each system?   i've seen vista transfer over wireless even though a wired connection was present.   unfortunately it doesn't automatically choose the faster connection.

for me its the reverse -- everything including the router reports 1gb and i only hav cat-6a cables (10gb) but still never get more than 35 MBps (vista to windows 2003 server)

The wireless connection was off.  But you're right about the misreporting.  The transfer speed is about 0.3 Gbps.  Not great but obviously better than the reported 100 Mbps.    Thanks for the tip!
