Hi All ,
I have been asked to help a friend set up a wireless network at home that her sons/Duaghter can access the internet etc from there laptops .... I have a unused Belkin F5D7633-4A ADSL router with built in wireless access point .will this unit connect to the telstra router ? we dont need to the ADSL part of this unit only the bit that will give us wireless .If it will connect can I please ask how one might go ahead and set it all up ? I have read a few postings on here and people seems to suggest to stay away from ADSL Routers is this true ?

The friends computer doesnt have a network card so Im pretty sure they are connected to the TC router via USB .

Thanks all for your time .
Cheers
V-S { Aka Andrew }

I don't think it will work, no - the ADSL is built in to that device, and I don't think there would be any way to connect any other internet connection (such as cable).

No, that modem will not work with TCL as it's an ADSL one and has no WAN port for connecting to the cable modem.

The second problem you face is that if the PC is infact connected to the cable modem via USB rather than ethernet that you are going to need to buy a network card for the PC as well as a new wireless router. Connection via USB port is certainly not recommended and the cable modem doesn't support connecting to USB and ethernet at the same time.

That Belkin does several things:

It's an ADSL modem

It's a router with NAT functionality

It's a firewall

It's an Ethernet 4-port hub

It does WiFi.

In order to have more than one PC attached to the cable modem (which is not a router by the way), you need function 2. Alas, 1 & 2 are tied together, in that (almost certainly---I don't know the precise details of the model) you can't do NAT through anything but the WAN port.

If you already had a router to give you multiple PC support but it didn't have WiFi and that was all you lacked, you could probably just connect a LAN port of the Belkin to your router and you would be in business. However, if you want the Belkin to provide the NAT/router then it is unsuitable for use on the cable network or any other Ethernet network.

If, on the router config page of the belkin, it has an option to use as access point, then it will work

What you would need to get it going is 2 Ethernet cables and a network card for your friends desktop.

To start off, get into the wireless router and turn off DHCP if it is running.

You would then plug the Telstra modem into one of the 4 ports on the back of the wireless router (NOT the WAN port) and run a cable from one of the 3 remaining ports in that section to the back of the PC.

Then you should be done.

Despite what is said above you should NOT need a new wireless router as the WAN port is only needed for routing (which the modem will do).

The only reason you may have a problem is if the Telstra modem does not have NAT (which should be checked before you do any of this).

You can check nat by plugging the network port directly (via cable) into a device with the USB unplugged and see if you get a local or international ip address. If you post here i can tell you which of the two it is.

hmmm.

I thought for TC cable DHCP had to be turned off in your local lan settings(on your pc) but turned on in the wireless router settings.

Its been ages since I set mine up lol.

Even if it wont work as above, you could just pick up a cheap belkin G wireless router on trademe or something for pretty much next to nothing Id imagine?

The force is strong with this one!

ArcticSilver The Telstra modem does not do nat. It can only connect to one device using a IP address provided by TC. So what people have said above is in fact correct.

Yep, the cable modem is merely a bridge, if I recall correctly.

"I have a unused Belkin F5D7633-4A ADSL router with built in wireless access point .will this unit connect to the telstra router ? we dont need to the ADSL part of this unit only the bit that will give us wireless"

I tried exactly the same thing as you with exactly the same equipment! I actually managed to get it working for a short time but each time I turned on the device that was connected by wireless (my PS3) it caused connection problems back at the PC.

So basically you can't do it. You need gear that specifically allows for cable internet connections (that Belkin model doesn't). I bought a cable-capable Netgear Wireless-G Router for $100 and connected that to the Telstra-supplied cable modem. Works perfectly now and very easy to set up.

If it does not support NAT a option would be to get a 2 port router (1 WAN 1 Local) and then plug it into your wireless access point or you could just buy a all in one wireless router.

I think he would prefer to use his existing equipment if he can - which won't be possible, by the sounds of it :(

Nope, it's not possible to re-use your existing equipment, sadly..

As a suggestion, I used a Linksys WRT54G to wirelessly network a cable connection when I was in America, no complain of product :)
