Apologies in advance for the duplicated thread, but I didnt realise it said there was a poll in the main screen, so I figured a lot might not read it because of that so here is the nekkid version
If you have a router and are having problems connecting to NTL/Telewest then heres why and how to get around it
The problem is that they have an invalid subnet which is being offered with an incorrect gateway
Routers are layer 3 devices so they wont route ANY packets to an incorrect gateway
What you have to do is manually enter your IP information but calculate the gateway address to the correct one
I was getting the following offered by DHCP
IP 082.037.160.118
SN 255.255.248.000
GW 082.047.072.001
Which wouldnt work because the gateway is on a totally different subnet, change the gateway to
082.037.160.001
and it works perfectly
Warning however, when your lease on the IP runs out if telewest still havent fixed it then if you get a different IP it will stop working and you will have to reacquire a DHCP allocated IP then do the same again. But until then the router will work
Also, if you dont know how to calculate the subnet via the IP and subnet mask its not quite as obvious as it seems as although the 160 in the third byte is copied "as is" were it to have been 163 as I had on another allocation then you would still copy 160 into that part of the gateway address. So if you dont know how to do that and just copying as is doesnt work you will need to find a util for working it out or ask someone who knows how to do binary masking as I am REALLY not going to explain it here
Hopefully this will help quite a few people to get back online through their router tho until Telewest redefine the faulty subnet scope or scopes
