Ethernet connection, Telewest

PaulSawers · 05-06-2006, 18:06

Hi, hopefully someone here will be able to help me. I'm normally pretty good with IT, techy stuff, so am stumped here.

I have just moved into a new flat, with Telewest Cable/Telephone Broadband. My room has a Motorola Surfboard 5105e (I think) modem. It seems to be working fine, all the lights are on (up until the 'PC ACtivity' light). I get cable fine, and the phone works fine. When I hook my laptop (Packard Bell, Easynote) up to the Modem via an ethernet RJ45 Patch cable, the modem doesn't detect the laptop and vice versa. I have tried the whole, turning the laptop and modem off and then on again, there is just no connection there. The modem says 'online', so it seems like it's getting a signal, it just doesn't like my laptop. Any ideas on how to overcome this? I've been into Network connections, checked everywhere to see if I can get the connection but no joy.

Thanks.

Do you have to have a cross over adaptor when using a modem?

I always thought you had to use crossover cable ? Could be wrong thou. Im assuming both your lappy and desktop are on the same Workgroup ?

You may be getting confused with set top boxes - some of which do need a crossover, but normal pc to cable modem should be patch (straight through).

But have you tried a crossover cable yet. You never know this might be the one occasion when you do need one.

A crossover is for when you need to connect two computers together to form a network, cutting out a router / hub.

A patch cable is used to connect pc to device, such as a cable modem.

Can your computer see the modem? Try typing http://192.168.100.1/ or http://192.168.100.2/ into your browser address bar.

Thanks for the replies. I haven't tried using a crossover cable (whatever that is) as everywhere I've read, it says I must use a straight-through, or 'patch' cable. My computer can't see the modem either, it's almost as though it's not connected. I have checked all the connections and it is plugged in. There is only one computer involved here, I don't have a desktop, just a laptop plugged into the modem via ethernet cable. It seems like using a crossover cable might be worth a try then...or is this definitely a non-starter?

Could it be an issue with your laptop? Sounds stupid I know, but is your network adapter installed (and yes, I have come across this!)?

No, you do not. A Cat5 UTP cable will work fine. By the way, you do have the USB cable unplugged when you have the Ethernet cable in, right? As far as I know, if the surfboard sees both USB and Ethernet plugged in, the USB will take precedence and the Ethernet will not work.

If your using ethernet on the 5101e or any of the cable modems
A: its a standart patch NOT at cross over, cross over on the old STB's
B: Do not have the ethernet cable pluged in.

Ok check you network conections screen see if theres a local area connection and do a ipconfig from dos post the results

Right, thanks all for your efforts. After spending almost an hour on the phone to Telewest Support, a solution has been found. I had to reset my IP page or address or something like that, through some DOS operating command. I am now connected via USB (as this didn't work before along with the Ethernet). So anybody else having similar problems to me, this may be worth a try if you know what you're doing. Last time I tried, the ethernet connection still didn't work, but I'm just happy to be hooked up and online.

what you would have done is a winsock fix. in dos "netsh winsock reset"

as for usb and ethernet they dont work together its either one or the other

glad to hear you got it sorted
