Hi Guys, wondered if anyone here may be able to help.

Basically all was fine with my friends setup until he upgraded the motherboard.
Now however we have a strange problem. I'll try and keep it short.

Standard blueyonder motorola modem which is connected via its ethernet port to a Belkin wireless gateway. The belkin is then connected to the PC via ethernet cable. Previously this worked fine, since the mobo swapout the pc no longer receives a valid IP address from the Belkin with the above mentioned setup.

If I eliminate the belkin and have the motorola going straight into the PC it picks up an ip and works no problem. Therefore I don't think its anything to do with the network card on the mobo or the motorola itself. I have tried connecting the Belkin directly to the PC as well (without the motorola) and it then shows an internal ip (as you'd expect) and I can access its web config. All settings within the setup appear fine.

To sum up then with the motorola connected to the belkin the PC only picks up a 169.x.x.x ip which clearly won't work. Does anyone know what may be wrong? I always thought it was simply a case of switching on the motorola, then switching on the Belkin, then disabling and re-enabling the network card on the PC and all should be well but continually getting 169 ip.

TIA
 
Hi mate,

I was thinking that but I'm pretty thorough and to be honest there isn't much to plug in wrongly. One thing I may need to check is the cable type which goes from the motorola to the belkin, this would need to be crossover I think? perhaps it's not? other than that I'm out of ideas.
 
Belkin is a 10Mb hub device and you need to set the NIC on the motherboard to 10Mb/half duplex manually perhaps? Or as you say wrong cable.
 
biffa thanks for the input, to the best of my knowledge the belkin is a wireless gateway and I think its a 125mbps one, I don't think therefore its a manual setting but I'll give it a go none the less as anything is worth a go, spent ages today without any luck.
 
You're confusing the wireless (the 125Mbps) and the wired ethernet ports. Tried the Belkin connected to another machine?
 
Could it be to do with the pc's mac address changing , as when I was on telewest a few years ago I had to clone the mac address into the router of my main pc to get the router and network running .

Telewest don't use that system any longer. Any MAC adress will do now.

Is it as simple as using the latest network card drivers ?

A mac change needs a power cycle and iirc has a max of 4 in 24 hours. Have you power cycled the modem ? Can you specify the IP of 192.168.100.2 on the PC and then log into 192.168.100.1 to view the logs ?

If its cable the belkin will have a hub or a switch on it.
 
thanks for the tips guys,

I'll try and answer:

I don't think the problem is actually with the belkin, I say this because the same equipment was working fine before the mobo change so although it could be the belkin it would be unlikely i would have thought.

Interestingly barrier0 mentioned cloning mac address, with the motorola unplugged I can access the belkins
web config using 192.168.2.1, indeed previously it had the old mac address for the old NIC, I then updated this to the new mac of the
new NIC, I actually thought that would solve it but still no luck. From what I've read and as ns400r said that telewest don't care about the mac now anyhow.

I'm going down there again today or tomorrow, possibly re-installing the network card drivers however if that was the problem I don't see why the motorola connected directly works. I'll also take with my netgear adsl router as I've read that even though it's a cable connection and the netgear 834 is adsl I can use that as a wireless gateway, that way I'll be able to eliminate the belkin. Could I be right about the cable type I need going from the motorola to the belkin? I thought the inputs were usually auto sensing however perhaps they aren't hence a crossover cable may be required.

Regarding powercycling, I did that a fair few times, thinking it would be as simple as powering everything off and then on again, starting with the modem, then the belkin, and then re-enabling the network card but no luck.

Thanks for all the input thus far guys. Will report back.
 
You don't need to clone MAC's.
Your not using the same MAC on the network card and the router are you ? ? ?
 
hmm...I do remember hitting the clone button? yesterday? Should that just be blank? I seem to remember deleting the mac in it initially but it re-populated the field automatically when I next looked. I'll double check, if thats the case I owe you one. I'll check soon enough.

You can't. You can use it as a wireless access point.
 
You'd get the same effect just connecting straight to the modem then, and you've already tried that and it worked...

As suggested, check MAC addresses - having the same MAC on the LAN and WAN sides would almost certainly screw things up.
