Hi All,

I've borrowed a wireless router (NetGear DG834G) off a guy in the office. I've got it plugged into my NTL connection via CAT5. The plan was to use the router as an access point (eg. Not use the ADSL modem it has).

I have plugged both my laptop and PC in via CAT5 and they can ping each other and the router. I have also tried using the wireless card in the laptop and it can still ping everything.

However I can't access the internet!

The IP addresses are as follows:

Router: 192.168.0.1 (Port 1 on the hub connecting to the NTL modem)
PC: 192.168.0.2 - (Port 2 on the hub)
Laptop (via CAT5): 192.168.03 (Port 3 on the hub)
Laptop (via Wireless) : 192.168.04

However the IP address the NTL modem had before I did an ipconfig /renew was 80.3.25.42. If I have the PC's connected via the router I can't ping this.

Both the PC and the laptop have ZoneAlarm but I turned that off before attempting to do anything.

Any ideas?????


Thanks,

Phill

Try plugging the wireless router into your original NTL modem.

Wall socket <-> NTL Modem <-> Wireless Router <-> PC's

Thats how it is.

Cable from wall <-> NTL Modem <CAT5> Wireless Router <CAT5> PC's

Yes (When connected via the Router)

If I just plug the PC into the back of the modem I get the following:

IP Address: 80.3.25.42
Subnet Mask: 255.255.255.0
Default Gateway: 80.3.25.254

What you are seeing here is the IP address allocated to the internet facing side of your NTL modem by NTL and the address of the computer your modem is talking to at NTL - the gateway.

When you plug the PC's in via the DG834G, it allocates IP addresses to the computers on your network (in the range 192.168.000.002 to 192.168.000.254 and tells them that it (192.168.000.001) is the gateway to the internet. So your PC's ask the router for a website and the router then tries to find that website down it's WAN input - the ADSL telephone line which you don't have. It won't by default look down any other ports (i.e switch ports 1,2 3 and 4) for an internet connection. That's why you can't connect. Some routers like the FWG114P have a Cat5 WAN input port for your kind of situation but the DG834G does not.

If you can work out the local network address of the NTL modem (an address similar to 192.168.000.xxx NOT 80.3.25.42) then you can manually set that as the gatway in your PC's and it might just work, but don't hold your breath.

if you have a link on your desktop to connect to the internet it will most likely be a webpage if you look in the address bar it should have an ip something like 192.168.1.2 if you try putting that as your gateway into the router it should work

I have the same router but connected to to a Mac, nevertheless I've just checked the instructions for getting connected via a PC. Hope this helps.

Firstly, I don't know anything about PCs but somewhere you'll need to tell the network you are connecting via DHCP, then

Launch your browser and type http://192.168.0.1 in the address bar, when prompted enter 'admin' for the password and 'password' for the password (both without the quote marks), this'll then take you to the Netgear Setup Wizard and it 'should' be plain sailing from there.
Good Luck, Paul

When I run the setup wizard I get the following message:

"The Setup Wizard was unable to detect the internet connection" - I'm guessing this is because I haven't got anything actually connected to the ADSL port on the Router.

I guess so - I've got a manual in PDF form that might help you. Email me through my profile if you'd like it.

PC's are set to pick up IP and gateway addresses from a DHCP server (in this case the DG834G) by default if one is available (unless this setting has been user modified). The only change needed is in the internet connection properties which should be set to 'Never Dial a Connection' but I don't believe that's the issue here.

No it wont be!! As I suggested earlier this router is not equipped to take a broadband connection in over Cat5 through one of the ethernet switch ports and then 'route' it. It has to come down the phone line as an ADSL signal. Your only hope is that the NTL modem has some routing capability and set that as the gateway, but I am not familiar with NTL's modems.

If you want to do what you are describing you need a different model of router, such as the FWG114P which has a special port to plug into a modem such as the NTL one you describe.

You've got it! Sorry to be the bringer of bad news.

Oh Well it was worth a try.

Can I not just use a wireless Access Point or will I need a router?

As arcturus says, DG834G's can't be used in the way you want as they only support NAT on the ADSL WAN.

Proper access point is the way to go.

As a temporary solution, could you connect one pc to the modem, then connect this to the hub on the router and use internet connection sharing? (Though the internet PC would always have to be on of course)
I'd get a combined ADSL modem/firewall/wireless router and bin the NTL modem

i think this could be the problem. on the wireless router you should have 5 cat 5 ports. (1-4 are for pcs) 5 is for modem be it adsl or cable.

plug your ntl modem into the modem port of the router (the one next to the antenna and away from the 4 ports)

you should then be able to run the wizard again.

when i setup a belkin wireless router on my brother's pc who also has ntl (this was after a fresh xp reinstall) i had to uninstall all the ntl internet stuff.
then just use the belkin (or netgear in your case) internet connect wizard and all works fine.

wireless is definately the way forward, once converted you will never go back

I've done wireless before at uni so I know its uses. I'm going to go and buy a CableDSL Wireless Router as it should have a CAT5 Port on it to plug in my NTL Modem.

Shouldn't be too expensive.

generally wireless routers work with both adsl and cable so shouldn't be an issue. the router you borrowed does have a cat5 port on the back for the modem.

just be aware of the problem i had when installing with NTL. i had to uninstall the NTL internet software, otherwise i couldn't get the router to access the internet. once removed, internet was accessible.

i have a buffalo router and its excellent. belkin good too.
