It's been a long time since I setup an old fashioned network at home....

I have just moved into a new house and signed up to TelstraClear broadband....
It's all installed and works like a charm with the ethernet cable connected to a PC....but I want to setup wifi in my house....how do I configure that?

I currently own a D-Link DSL-G604T wireless ADSL Router....how can I use this to setup a wirless network?

I have tried pluggin the ethernet cable coming from the TelstraClear cable modem, directly into one of the LAN ports of the Router, and have inputted everything such as the static IP address, gateway, DNS...etc etc....but still have no internet connection?

My computer can connect to the wifi/wireless network just fine...but no internet connection.

I am assuming I do not have to plug the cable modem into the ADSL port on the Router as that is for an ADSL modem.

Any help much appreciated

I don't thonk you have any luck with the adsl modem. You need to buy a router with no modem built in

Yep, you need a non-dsl router to work with telstra clear cable modems.

The cheapest way would be to connect the cable modem to a basic wired-only router, the connect that to your d-link to use the wireless function of it.

The simplest way is to get something like this http://www.ascent.co.nz/productspecification.aspx?ItemID=364367, which plugs directly to your cable modem, and you can throw the d-link in the bin (figuratively at least)

Sharing a cable modem on your lan is not quite as easy as sharing dsl, unfortunately

This, or the Linksys WRT54GL (http://dicksmith.co.nz/product/XH9447/linksys-wireless-g-broadband-opensource-all-in-one-wrt54gl), or the Cisco SRP 521W (for a very high end model)...

I use a WRT54gs myself, with DDWRT firmware loaded.

Hi Euan, most more modern routers well out perform the WRT54GL with stock or 3rd party firmware loaded, whilst firmware such as DD-WRT offers truck loads of options and features, the requirements of most home users (even advanced ones) is catered for by the stock firmware on your average router these days. This may not have been true 5yrs ago, but in that time since most vendors have well advanced the power and capability of their modems (just like phone cpus and desktop cpus the mip rating of all devices has climbed exponentially).

I recommend you get a N router, stick with brands such as Lynksys, Dlink and TP-Link and get one of the models in a $100-$150 range with N and your good to go.

I have linked a online site that has a good selection, remember you need a router (with integral Wireless AP) rather than just a Wireless AP, its the NAT router that lets more than one PC use the connection.

You can use the DSL-G604T as just an access point, as I used one in this configuration for several months a while back (a rev. B model). The only difference was I had a seperate ADSL modem for the connection to the outside world, where you have the cable modem.

You will need to turn DHCP off (so that the cable box allocates IPs), give the DLink a static IP in the right subnet for your cable modem, and plug the ethernet cable in to one of the LAN ports on the DSL-G604T.

From memory, they are only 802.11b/g and WPA is the highest security supported, but it should get you going...

Yep you can do that, but with no NAT router, only one PC.

The cable box doesn't allocate IPs and has no IP address itself, it's a dumb box. Your PC or router has/sets the IP address, and must also do DHCP if you want to run a local network.

It might be possible to make it work, but the easiest plan is to buy a cheap WAP.

I stand corrected

I (wrongly) thought the cable modem boxes were capable of performing NAT functions as well.

I second Mauricio - I used the WRT54GL and its fine. In fact I still have it, having moved to the provinces and no longer being able to get TCL cable (damnit). I should get around to selling it I guess but maybe one day it will be useful again...

TCL Cable modems are simply bridges, no NAT, no DHCP (that is of any use) no layer3 functions at all.

Of course. You need to turn off the DHCP on your modem, but first set the modems LAN address to something that will allow you to access it from the LAN address range on your cable modem's network. For example, if the cable modem's LAN address is 192.168.1.1 then adjust it to reserve an address such as 192.168.1.254 for your adsl/wifi router. After that, turn of the router's DHCP and plug a LAN port into the cable modem. All addresses will then be supplied by the cable modem.

If it still doesn't work, you might need a crossover ethernet cable to connect the 2 modems/routers.

EDIT: Cable modem doesn't have NAT? hmmmm, you must have a router there already to be using more than one PC on the LAN, otherwise you might need an ethernet/wireless router or residential gateway?

Time to find a new industry!
