My problem is when setting device to auto-negotiation and PC to auto-negotiation or 100 full duplex and plugging crossover cable, I can see twoLED indicators on both side blinking together at the same time about once a second. It does make sense because one of LEDs should be solid green for Ethernet link established. After that, PC becomes slow and "display driver stopped responding" message shows up.
But I do the same thing to connect the PC in Windows XP and device, everything is fine. PC can detect stably of the network link with device and data transmissions are stable with the following network setting: PC – 100 full duplex; device – auto-negotiation.
And I also make an experiment in Ubuntu. It turns out that under the same situation, PC still can detect the link from device. If I use straight cable with switch to connect them (all OSs), there is no problem at all.
I just can't seem to figure it out. Anyone have any suggestions? Thanks in advance.
