I am using linksys befsr41 router as a switch.
My pc using onboard Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC, winxp sp3.
When i connect my pc to the “switch”, the nic will prompt “cable unplug”, but on my router the “link led” will keep “blinking”.
But when i connect the pc to directly to my gateway router or another pc, everything is working.
My other pc work just fine with the “switch”.
My opinion is that the “switch” detect that the nic is up, but the nic detect that the “switch” is down, judging by the “link led”. BTW the leds(green and orange) at the nic did not light up.
I read on the cisco site that this problem may occur when one of the device may not have ‘autonegotiate’ enabled. If A enabled, B disabled, then A will show that the link is down where as B will show that the link is up.
In my case, i think the “switch” is B and pc is A. But i doubt this is the reason because all my other pc is using ‘autonegotiate’ and they work just fine.
Anyone have any solution to this problem?
P.S. can you tell me the real problem too if you happen to know.
Edit: I found a thread in another forum that is asking the same question as mine. same router, same nic and same problem. but there was no reply. It was posted on dec 2007. And no, it was not me.
