problems changing from USB -> Ethernet

lf86 · 20-04-2004, 16:58

hi all,
im running windows xp and I have a terayon tj210 cable modem, I've used the USB connection since i first got bb, have been attempting in the last few days to make the switch over to ethernet, ive read so many help guides etc and it all seems so EASY (!) but mine is being an arse. Windows is reporting the connection as 'network cable unplugged'. Now I've tried two different realtek NIC's, straight-over and cross-over cable (as I wasnt sure which one it was the cm needed, both brand new cables anyway) and I've left the modem powered off for around 30 mins or so, as I had read in some places. None of this seemed to work. So finally the only thing I can think of is that maybe I need to let the IP lease expire? As in leave it for 12 hours?
all help gratefully received,
Liam

If it is reported "network cable unplugged", this is a hardware problem, and nothing to do with lease expiry or powering off the cable modem. You need a straight-through ethernet cable to make the connection between your Terajet and your ethernet card. When you have a working ethernet cable in working ethernet sockets, you should get a green LED light beside your ethernet NIC RJ45 socket, and an LED for the PC connection should light on the Terajet as well. If you don't have these LEDs lit, you don't have an ethernet connection, and no amount of twiddling with software or lease times will fix it.

The possibilities you need to consider are:
1. Terajet ethernet socket faulty;
2. Ethernet cable faulty, or not straight-through;
3. Ethernet NIC socket faulty;
4. Ethernet NIC not properly seated on motherboard socket.

If windows is showing 'network cable unplugged' and everything is actually plugged in then there is a physical problem with the wire between modem and PC.

Are you sure you have tried both x over and straight through cables?

OK thanks for the help Robin, I am thinking its probably reason 4 - my case is poorly designed and therefore I cant screw in any PCI cards properly but it seemed to me like it was in. Maybe I'll have to double check it - I had presumed that if the card wasnt inserted properly that Windows would report that the card wasnt functioning properly....nevermind.

p.s i know im probably the trillion'th person to say, but your site is a bible.

OK made sure the card is definitely inserted right, but none of its LED's are lighting up (they do work, I have used the card to network computers in the past)
I'm beginning to think that perhaps the terajet ethernet socket might be faulty after all, seeing as everything else is working or I've removed it from the equation.
there's absolutely nothing else i've missed? I dont want to resign myself to the fact that my CM is faulty.

It wouldn't be the 1st ethernet socket on a Terrjet to be faulty.

You should verify which end is faulty by borrowing a friend's PC with an ethernet socket to see if it can connect to your cable modem, and then try your PC on his cable modem.

If you find that your cable modem is faulty, you could ask NTL to supply a new one: one of the badged Ambits.
