LAN Displayed Connection Speed

I had a friend who called about his network. He has a 10/100/1000 Mb network adapter on auto negotiate. I asked him what his connection speed was by double clicking the LAN icon in network connections. Win XP. He reckoned it showed him connected at 2Gb. I haven't seen it yet as he stays a bit away from me, but is it possible for a network adapter rated at 1000 Mb max to display itself connected at 2000Mb. My understanding had been that if it is a 1000Mb ethernet adapter, then the maximum it could ever display itself connected at would be 1000Mb

“Is it possible for a network adapter rated at 1000 Mb max to display itself connected at 2000Mb”

NO

All 10/100/1000Mbps, Lan Card Network Adapter will only connect to a broadband modem or router

at the default speed of 100Mbps

At present there is no broadband Cable/ ASDL Modem /Router that will allow you to

connect to the Internet at 1000Mbps the standard connect speed is 100Mbps

If your local network is via a 10/100/1000Mbps switch than the connect speed of the computer to

the switch would be 1000Mbps, but will still only connect to the Internet modem / router at 100Mbps

Thanks for the reply. I felt the same, but you just never know, and it's nice to have it confirmed. It didn't make logical sense to me either

Thanks

Possible, but only with CAT6 cable

As gigabit ethernet must use full duplex, the max theoretical throughput is 2000Mb/sec. 1000Mb/sec each way giving you a total of 2000Mb.

I do have to point out this is theoretical output!!
