NIC will not conect at full speed.

Guest

I am runing Windows XP Pro SP2. I have a NIC that if set to automatically
detect network speed or to run at 100 Mbps constantly tells me that I have a
network cable unplugged. If I set it to run at 10 Mbps half or full duplex
it works fine. I have tried replacing the UTP cable and the port on the
router to no avail. I have also replaced the NIC with a new one and still
have the same problem. All of the other computers on the network have no
problem with connecting at full speed. I have had this problem before with
this same computer and set it to run at 10 Mbps and left it alone but I have
since done a full reinstall of Windows and the problem resurfaced. Any help
would be greatly appreciated.

This is not likely to be a Windows issue. What sort of switch / hub do you
connect to? Have you tried another cable? another switch port?

YEs I have tried replacing the cable and also changing the ports that it conects to my router on. I am using a linksys befsx41 router. I had a linksys lne 100tx NIC and replaced it with a DLink DFE-5300tx+. Seeing as how all of the other computers hooked to the router connect fine and that I have switched ports on the router and cables to known good ones and installed a new network card a software problem was the only thing that I could figure out might be the cause. Thanks

That is indeed odd. I really can't see how this would be OS related, esp as
you've tried a new NIC - I'm not sure what I'd try, honestly....sorry I
couldn't help more. You might check out

http://www.experts-exchange.com/Networking/Broadband/DSL_Cable/Q_20418688.html#7552492
.....someone said they had this problem & it turned out to be a flaky power
supply....or a video card that was acting wonky.

Googling for
"windows xp" "network cable is unplugged" autosense NIC

got a bunch of hits, and you might try looking there.
