You are not tied to a particular router that is nonsense. there are loads of people on here using wireless routers of various makes with ntl. A wireless router will cost you less than 100 euros - and its not especially difficult to set up.

Friend of mine who has NTL is currently using this for example:http://netgear.co.uk/extra/h_wirelessrouter_wgt624.php

NTL supply some customers with a netgear router. Prob the one Dub45 linked to. But any wireless router will work. I personally recommend the Linksys WRT54G. Widely available and top quality.

Another example of NTL tech support talking shite. Last week someone was on here saying that they had been told by NTL that using a router was not possible! Morans!

Yep loads of people use the Linksys one especially but the reason I did not mention it was that the current version (version 5 I think) has lots of problems.

irlrobins

I think most of the "problems" relate to the fact that you can no longer install third party firmware on it like you could on previous versions. But since most people stick to the official firmware it's not an issue.

Edit: remembered that Linksys released the WRT54GL, which allows you to install third party firmware as before.

The older linksys wrt54g is probably the best wireless router I have ever used.

Its being going nearly a year now uptime wise and Ive never had to power cycle it.

Assuming you can get a strong wireless signal, for the most part you won't experience any loss of performance.

802.11g supports a 54Mbps signal. Your NTL service is officially a max of 6Mbps. So under optimal conditions, you woun't see any degradation of service. Having said that, wireless is subject to various sources of interference, and the actual throughput that you receive depends very much on local circumstances.

Also my dad has an Eircom wireless router in work, he said that a mate said it should work fine for us, I wasn't too sure. Does anyone know it if would?

It can probably be made to work.

Assuming it's a DSL modem/router, rather than just a plain router, just follow the suggestions in this thread.

post output of ipconfig /all while connected using wireless here.

1) Connect PC/Laptop to wireless router (if you can get this far).
2) Start->run->cmd
3) In the command prompt that opens, type ipconfig /all
4) Copy and paste output here

So the wireless network is using the 192.168.1.x subnet. What IP address did you have when you used the wired connection, and could reach the internet?

Ok that's if you plug cable modem directly to the PC it seems.

Your ip settings when you connect using wireless seem correct. Can you give more details about how you connect cable modem to the wireless router?

Ah there's your problem. Yellow was big among routers last year but this year they refuse to work with any thing but dual colour cables. Try painting a red stripe down it....

Ok I'm kidding. CAn you descibe in detail your setup. Obviously you have the NTL cable modem. But what model is the eircom router? Which port on the eircom router do you plug the cable from the NTL modem in? What port do you plug your PC into on the router? etc.

Actually the yellow cable could well be the problem as yellow ethernet cables are crossover cables. This is fine for connecting the cable-modem directly to the PC, but when connecting it to a router you should use a straight through cable. If you haven't got one already then get one, they're pretty cheap.

irlrobins

Not strictly true, I have crossover cables that are grey and red.
And I think many routers autodetect if you're using a crossover cable or not and adjust accordingly.

Anyway see what OP comes back with and take it from there.

irlrobins

Yep, spot on.

Ok keep that setup, and connect ur PC to the router using the wireless.

Then do this:

1) open command prompt (Start->run->cmd)
2) Type ping 192.168.1.254
3) Type ping 82.195.136.250
4) Type ping www.boards.ie

Disconnect wireless. Connect PC to router using ethernet (plug it into one of the 3 remaining LAN ports)

Repeats steps 1-4.

Let us know, which if any of those ping tests fail.

No, it is true that all yellow cables are cross-over, not all cross-over cables are yellow though. If either the Eircom router or the cable modem doesn't support automatic detection of cable type then it's not going to work and would result in what Solitaryman666 is seeing.

The pings should reveal a bit more but from what has been said already it seems to be a problem between the router and modem.

Agreed. I have a feeling it's a DNS issue. But pings will tell more.

That's your problem. The yellow ethernet cable coming from the NTL box has an IP address of 81.103.240.243. But you plugged it into a LAN port on the Netopia, which expects a 192.168.1.x address. You need a router to get from 192.168.1.x to 81.103.240.243 but you're bypassing the router functionality of the Netopia, by plugging into the LAN side. (I know you don't have the option of plugging into the WAN side, because it's a DSL router). Unfortunately, if the NTL "modem" is giving you a "raw" connection, without any NAT protection from worms and other nasties, then there isn't really any reliable way to use the netopia 3347WG with it.

irlrobins

ah bugger, think you're right. I just assumed it would work, even with a public IP.

No, sorry. My original suggestion was based on using the Netopia as a switch, because I assumed that, in this day and age, no ISP was so irresponsible as to give non-technical customers a "raw" connection, and that the NTL "modem" would provide a NATted address.

Yea that's what I was going for. Well you learn something new everyday.

jor el

Ah, the cable-modem is similar to the IBB breeze box then. A friend had that and we needed to connect the Breeze box to the WAN connector on his wireless router. I had forgotton about that and was wondering why he needed to to that.


Does that router have a WAN port on in Solitaryman?

irlrobins

yea it does but it's RJ-11 and not RJ-45

The netopia 3347WG is a DSL "gateway" - it's WAN port is actually a DSL "modem", not an ethernet port.

Except irish broadband who dump half a city on a subnet with you just to fill your firewall logs with crap.

I think you'll need a new wireless router, one with an RJ45 WAN port on it. Your current router just isn't gong to work unfortunately. I think the one my friend had on IBB was a USR 5462. I'm sure there are others but I don't know of any off hand that have the required WAN port. Perhaps some one else with a wireless router could recommend one. This one might do the trick, but I'm not 100% sure.

irlrobins

Yea second link will work fine. Prob the most popular wireless router out there. I have one and it's easy to use and I haven't had to reset it once.

The vast majority of avalable routers fall into this category. They are usually referred to as "broadband routers" because they can work with different types of broadband (DSL, cable, wireless), whereas "DSL gateways" can only be used with DSL.

The "Big 3" brands in the consumer space, Linksys, NetGear and DLink all have multiple models of "broadband router" available, and usually only one or two "DSL gateways".

With the recent news that Netgear are to locate their International Headquarters in Cork, maybe you should look at a Netgear router.

Explain this bit of logic?

racer25

Maybe you will get support....

Sending your broken Netgear to USA might take while. Not that they should break but......

Maybe support/repair service.....

Sending a product back to the UK is slow......

irlrobins

Yea but most times when a product fails you return it to place of purchase and not manufacture. So lil difference if Netgear are here or not.

Course if you have to ring support, maybe you'll get a nice Irish accent at the the end of the line.

Probably forwarded to a call centre in India
