Ntl broadband sharing via router trouble

edthegr8 · 20-09-2005, 18:49

hi guys
we live in a student house and wish to connect 4 pcs to our one ntl broadband cable modem via a router.
we have set up the router and modem in a way that follows on from the following post on this site:

http://www.cableforum.co.uk/board/showthread.php?t=8269

However, the only pc that is able to access the internet is the first one booted up after the modem and router are turned on (each being given time to settle). It does not matter which is the first pc booted, thats the one that works and the others will not.

Have tried the following from the not connected PCs

Start>Run>CMD>IPconfig/All
>ping ping 192.xxx.x.x

which gives four replies. I was told that this indicates the router is working and that there is a problem with the workstations, but given that each workstation has been connected in turn im confused????

Have we missed some part of the set-up out?

Many thanks
Ed

Have you run the NTL setup cd on all 4 pcs?

Maybe a bit obvious, but are you sure you have connected the cable modem to the WAN port on the router? The symptoms you are getting would be probably occur if you had the modem plugged into one of the LAN ports.

If you already have an ntl connection, you only need the CD if you're connecting directly to the modem with USB - since you're using a router edthegr8, you obviously aren't.

In common with most ISP supplied software, the ntl CD is best ignored unless, as I said, you need the USB modem drivers. Since you get the option of connecting to your ntl modem/settop box with ethernet, which is far better for a good, reliable connection than USB, this means you only need the CD if you don't have an available ethernet port. And even at that, you'd be better off getting an ethernet card.

This is very strange behaviour for a router, though. Would help if you posted what make & type it is.

I am told (this may seem strange, but i have not seen the router because i have not moved in yet - but my housemates are all on work placements so i have taken the job of trying to sort the net out) the router we have has no markings on it other than:

'10/100 Auto Midi/Mdix'

There are eight sockets with labels tx1 tx2.....tx8.

we have connected the cab. modem to tx1
and the pcs tx2-5.

Is it a case of a new router?

Is there nothing at all that looks like a model number etc? Are you sure it's a router or could it be a switch?

edthegr8 · 20-09-2005, 20:21

to be honest i just dont know, not having seen it but i am assured that those are the only markings. i am gonna check again now though with my housemates

From what you have described this router is only giving off 1 active ip address,what ip addresses are all the pc's getting from the router?.

Are they all the same or different.

edthegr8 · 20-09-2005, 20:31

i believe they are the same

Ok thats your problem they should be getting slightly different ip addresses.

Example pc 1 could be 192.168.2.1 then the second 192.168.2.2 and so on.

The pc's are set to obtain ip addresses automatically?

mate, this isnt a router its a switch there.....you need a router, standard routers have only 4 ethernet ports, switches vary between 4 and 24 at least the ones that are affordable. so get yourself this little thing here and you save yourself a lot of trouble.

edthegr8 · 20-09-2005, 20:34

yep to the obtaining ip addys auto set up.
def. a switch then? how clever are my housemates?

so a switch would still allow one pc to access the net in the way that has been happening - it seems as if the modem connected to switch connected to pc is doing the same as would happen if the modem was connected direct to one pc.

That would explain a lot LOL.

Nice cheap router with a print server there, maybe we should ask for a review if it works for the poster
