Hello,
I've a D-Link DFE-520TX PCI Fast Ethernet card, which is/was excellent until this first problem. 2 nights ago there was some good lightning/thunders activity, resulting in burning of ISP network switches. This morning they replaced the switches and brought up the network, but here's the problem:
1) Under the default card setting with Auto-negotiation, PC looks for DCHP Server address resolution and ends up with YELLOW triangle in the system tray.
2) Whereas, when I CHANGE the card setting to 10Base in FullDuplex, then PC gets connected to the ISP network.
ISP support said that either the card could be damaged due to lightning strike or it could be due to damaged cable running from port box to the PC (RJ-45). I'm wondering, could lightning strike damage a Network card in such a partial manner (just one feature, i.e., Auto-negotiation)?
But that person warned, there will be deterioration in ISP speeds when I use 10Base in Full Duplex (for now) compared to Auto-negotiation speeds. Speeds really came down badly, that's understood.
Main question is, Auto-negotiation card mystery? I'm not sure if the problem in the card or in the Internet cable.
Please suggest,
Thanks a lot.
