Ntl broadband sharing via router trouble
 

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?

Re: Ntl broadband sharing via router trouble
 

:welcome: 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.

Re: Ntl broadband sharing via router trouble
 

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.

Re: Ntl broadband sharing via router trouble
 

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?

Re: Ntl broadband sharing via router trouble
 

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?

Re: Ntl broadband sharing via router trouble
 

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

Re: Ntl broadband sharing via router trouble
 

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.

Re: Ntl broadband sharing via router trouble
 

i believe they are the same

Re: Ntl broadband sharing via router trouble
 

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?

Re: Ntl broadband sharing via router trouble
 

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.

Re: Ntl broadband sharing via router trouble
 

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.

Re: Ntl broadband sharing via router trouble
 

That would explain a lot LOL. :Yikes:

Re: Ntl broadband sharing via router trouble
 

Post 6 lol ;) Nice cheap router with a print server there, maybe we should ask for a review if it works for the poster :)

Re: Ntl broadband sharing via router trouble
 

Ed, yeah I would give your housemates a 3 outta 10 for knowing what they should get. A switch allows 1 computer to go on the net at anytime...never more then that unfortunatly or you have to have a really advanced switch from say Cisco and those come with a nice £ÃÆ ’‚£Ãà¢Ã¢â€šÂ¬Ã…¡Ãƒâ€šÃ‚£ tag on them. so my best bet is get a proper router and you'll be up and running within 5 mins if you dont get yourself strangled in the wires ;)

Re: Ntl broadband sharing via router trouble
 

right, firstly thanks guys for help diagnose a classic case of computer illiteracy,i didnt mention it earlier to avoid complication, but there is talk of a fifth laptop. we either need a router with 8 ports and use 5, or can we get a 4 port with wireless access too, and have the 4 pcs wired along with the laptop wireless.

any suggestions on routers?

thanks for all this help guys, its much appreciated.

Re: Ntl broadband sharing via router trouble
 

Ed, okay you can get the router and still use the switch :) just plug the switch on 1 of the 4 lanports or if you really want wireless try this 1 okay I dont know how good it is but looking at the reviews it must be okay.

advice okay Belkin is "okay" (guys please dont castrate me for this) and it comes with a nice lifetime garantee so if its fooked then you can just have it replaced.

Re: Ntl broadband sharing via router trouble
 

so if i connect two computers to the switch one of the two can use the internet at any given time, alongside the other three computers that are plugged into their own sockets?

or if i get the suggested router i can have all four wired pcs, and a finite number of wireless machines connected to the net at once?

i take it because we have 2mb bb access, the 22mbps of the router is insignificant?

Re: Ntl broadband sharing via router trouble
 

errr Ed, I edited the link to a better router....the 22mbps is a 801.11B protocol and which is C R A P.

on the wireless router you can have up2 normally 64 pcs but at work we recommend to stop at 32 but even then thats not something that your average home user will have.

the speed of the Wlan is significant in someways say you play games and stuff on the laptop then you need faster.

with regards to the switch your correct in that....only 1 pc can get on the internet at any given time. but then if you connect the switch to the router you can have an infinite number :)

Re: Ntl broadband sharing via router trouble
 

so a 8 port switch connected to a 4 port router in effect creates a 11 port router?

how do the router and switch connect, do we take a cable from the router socket to any of the switches sockets?

Re: Ntl broadband sharing via router trouble
 

Is this thread and this thread related???http://www.cableforum.co.uk/board/sh...358#post582358

The poster here says its a Safecom SBRU-10100 which a quick google tells me its a router???

Might not be related as I spose theres a lot of students moving in this week ;)

Re: Ntl broadband sharing via router trouble
 

no not related m8.

Re: Ntl broadband sharing via router trouble
 

lololol :P


not related.. but related.. i guess :D i dunno if its only with me.. but that router suggested up there.. is CRAP!!! i definetly wouldn't get that if I had the option. I guess you get what you pay..

my setup is quite similar to yours except we have 5 laptops already which creates the problem that most routers (wireless) only have 4 ports..

anyway, if I can't sort out my problem with the Safecom router, I'll be buying a Linksys WRT54G. Use this router back home and works like a gem! :P

Re: Ntl broadband sharing via router trouble
 

Maybe the forum should have a students section for a week or so ;)

Re: Ntl broadband sharing via router trouble
 

Yes
Pretty much. The switch should be intelligent enough to know which IP addresses are on which ports, however it is not capable of giving out IP addresses as it does not have a DHCP server built into it.
The Linksys WRT54G would be the router I would recommend, that will sort out the DHCP issue and also be wireless should you want to switch that on (and you can leave the wireless disabled until you have something that needs to wirelessly connect to it.

Router and switch
 

I am still slightly confused. If we connect 3 computers direct to a four port router, with a 8 port switch connected to the routers fourth socket, can we have 5 pcs on the shared internet at once. - 3 directly connected to the router, and 2 connected to the switch.

Or, can only 1/2 pcs connected the switch access the net at once? hence only 4/5 pcs can be on the net at one time?

Sorry if im being stupid.

Ed

this link will explain the difference between routers, hubs, & switches

Re: Router and switch
 

No you're right, you could connect an 8 port swich to each of the 4 ports on the router and have 4*7 28 PCs / devices connected to the router. Most routers can handle at least 50 devices. Just without something routing the traffic and handing out specific addresses for each device you are stuck.
A switch can learn where an IP address is in relation to the switch, but cannot create an IP address for a location.

Re: Router and switch
 

You can get routers with different numbers of ports - for instance, the Linksys BEFSR81, which is an 8 port router.

Re: Router and switch
 

I have one of those connected to http://www1.linksys.com/internationa...oid=6&ipid=604 and it gives a great ADSL link (connected to Demon).

Re: Ntl broadband sharing via router trouble
 

I recommend getting a Belkin router, runs like a bloody dream! :)

btw, dont forget to go to portforward.com to open the right ports etc for apps :)
