NTL 250 modem + linksys WRT54G router

Maroon · 17-11-2007, 07:25

Had a V+ box installed yesterday and the broadband changed from using the old STB to a new NTL 250 modem.

When I tried to get connected nothing was happening through my router but I managed to get it working directly to the pc.

I been trying since to use the router again but with no joy so far.
I've tried the powering down and up again.
I'm guessing I shouldn't have to but I've also tried cloning the PC's MAC address - but to be honest I'm not sure I was doing that right.

Can soemone point we in the right direction please.

Many thanks
Martin

You needed to set up the modem connection first, before you could get the router going. Remember you must reboot the modem for it to recognise you've swapped to the router. You need a straight through ethernet patch lead between the router and modem (some STBs used a crossover)

I'd suggest you do a factory reset on the router, get it back to the default settings and go from there.

Martin,

You should clone the MAC address on the WRT54g router.

From memory, you open up a command prompt and type ipconfig/all. This provides the physical address of the network card that has been registered to the modem. This is then entered in the clone section of the WRT54g configuration.

Connect the router to the modem & everything should be OK.

Why do people insist they need to clone the mac address of a registered PC into a router to get the modem to router connection to work? It's not necessary.

This was only of benefit to the users of Set Top Box connections where the specific connected device needed to be registered with the Virgin Media servers. With a modem connection it's the modem only that is registered so it doesn't matter what device is connected to it computer(s), router or console (just one at a time though).

Well my connection would not work, with my router until I cloned the address. Saying that it was three years ago, though I have never had a set top box.

I too had problems installing a router and had to go the clone route.Again, that was several years ago. I have since installed a modem for a grandchild without having to use this route.In neither case was it a Linksys .

Thanks for the advice but I've still not got it working.

I had to replace a connector on the patch cable to make it straight through and that's working fine.

I did the factory reset on the router and tried again rebooting the modem but still nothing.

I've also tried the clone mac address part again without any luck.

Any more ideas?

Thanks

if the internet works without the router & you are trying the router with wired connection & it is set to the defaults of 'dhcp server enabled' & 'obtain an IP automatically', & it doesn't work, then it tends to suggest a faulty router, sorry.

To confirm, as Rob has said, unless you have to register your network interface card MAC address, which you do not on VM now, you do not need to clone your routers address to match that of your PC's NIC.

I set up my friends linksys last night, and his router obtained a new IP address about 5 minutes later, you just have to be patient.

If I were you I'd buy another patch cord. I've never had much luck with replacing plugs.They're not exactly expensive after all.

I received my new 255 modem today and to get my internet working through the router I had to boot the modem up first and let the SYNC and RDY lights go solid and then boot the router up.

I never messed around with cloning MACs or anything.

It is looking like the router is faulty...

All the settings are as you say and I've double checked that the cables in and out of the router are working ok. Also I connected my laptop directly to the modem and this worked fine.

When I connect the router to the modem the Internet light comes on as normal. And the pc can access the router so I can check the settings and do the factory reset.
The router was working perfectly before the new modem. Is there anything else I can do to confirm that it's the problem? Apart from just buyng a new one!

I had a similar issue with my lynksis earlier this year, hit the reset button on the back
Power off everything, Switch modem on, then router then pc. It worked for me, I also rang lynksis helpline but they just talked me through the above proceedure. Might be a issue with the DNS settings. Can you access the status page on the router, if possible post a picture.
Good Luck

Looks like internet is not getting to the router, you have nothing in the Login Type, I have the same router as yours. I am no expert on this, but it isn't right.

If you will copy your settings of the set up page here, I can compare that with mine.
