If I had a Dlink DIR-615 wifi router

http://www.dse.co.nz/dse.shop/4da01708010b12302741c0a87f3b0624/Product/View/XH0578

And I wanted to connect it to my dsl modem(which has 4 ethernet ports) which I already have, how easy would it be to do? Would I just run a patch cable from the DIR-615 wifi router internet port to my dsl modem's ethernet port and then whenever I connect via wifi to the dir-615 will I be able to access the internet?

A) Purchasing the Dlink DIR-615 router isnt the easiest way to go. Just go and properly get an all-in-one dsl wireless router, rather than just a wireless router.

B) If you must use the DIR-615 the follow these steps.

1) Reset both your ethernet dsl router, and the new dlink
2) Plug your computer into the home router and set it up to use the internet. Write down the LAN ip address and subnet mask of the ethernet router. Then on the DHCP settings page, set it to issue ip addresses ending in x.x.x.3 to x.x.x.99

3) Plug your computer into the dlink. It will get an ip address of something like 10.1.1.2. write down the gateway address that it gets and open it in your web browser. eg. http://10.1.1.1
When in the dlink programming web interface, you need to do two things.
- Program the wireless settings. Use WPA2-PSK and TKIP with a passphrase of your choosing.
- Set its LAN IP address to be x.x.x.2 (the x.x.x.? come from the gateway address you wrote down from the first router) So your main router might be 192.168.1.1 or 10.1.1.1 or 10.1.1.254, this one will be 10.1.1.2 or 192.168.1.2
- Disable the DHCP

When that is all done, join the two routers by connecting port 1 of the ethernet router to port 1 of the wireless router. Dont use the WAN plug on the new dlink.

By following the above steps, you have made the existing router the main unit that issues ip addresses. And the Dlink has become a dumb network switch or plain access point. At the same time you have avoided double natting by not using the WAN port on the new DLINK and it should now be working both wired and wirelessly.

Alternatively, setup the ADSL modem for half-bridge mode and use your new router as the NAT router that creates your LAN. Half-bridge often goes by other names and may not have instructions for this feature. Then you can use the firewall features of your ethernet router and avoid double NAT or problems caused by the insufficient memory of some DLink ADSL modems handling torrents etc. If you can find out how to do the setup, it will basically do the PPP login for you and pass all incoming traffic to your router by allocating the external IP address directly to the router.

Do I use a crossover cable to connect the dlink router to my dsl modem or a patch cable?

These days, all network devices have crossover detection.
So it shoudnt matter if you use a crossover or straight thru cable.

I found some easier instructions here:

All current D-Link ADSL modems have PPPoE capabilities. That means that the modem carries out the authentication with your ISP. Hence there is no need to enable PPPoE on your router when using such modem.

Connect the modem to the WAN port of your router.

Connect your computer(s) to the router's LAN port

Open your Internet Explorer and log into your router by typing in its IP address

Under 'My Internet Connection is:' select the 'Dynamic IP (DHCP)' option. Leave the other options on this page as they are.

Would this work?

Hi, no that will not work as all Telecom connections use PPPoA not E. The instructions given by Ray are what you need, and to layer2 bridge your wireless router is by far the cleanest way to connect the two.

Will this work with a D-Link storage router DIR-685 (which is similar to the DIR-615 - but it has a built in storage drive that all the computers in the network can share).

The question is - How do I get my ADSL modem (standard Telecom one Thomson TG585 V8?) set up in half bridge mode?

You should start a new thread for that as its a different issue.

I dont think the thomson are customisable enough for you to setup things like half bridge mode etc

If I got a wireless linksys access point and plugged it into the ethernet port of my dsl modem, would I just need to connect to the linksys access point and then the internet will work?, so I won't need to worry about bridge mode or anything else?. The access point I am thinking of getting can be viewed at http://www.dse.co.nz/dse.shop/4da9623c0240a46c273fc0a87f3b06cd/Product/View/XH9930

Yes indeed it will
However, spending more on getting an 'N' access point wont make your internet faster.
A 802.11g access point is still faster than the DSL broadband to your house.

Search DSE for WAG120N
Its still an N router, but has the DSL part built in, and is much cheaper at only $119 so you will only need the one device.

Even better would probably be the D-Link XH6497
If you dont know how to program a modem from the web interface then the Dlink would probably be better. As the setup software with the linksys is crap - bloatware.
The linksys will still work fine if you set it up through the web interface and dont use the CDrom but if you must use the CDrom then the dlink will be better.

Dick smith have a crap website where you cannot copy and paste the URL of a product page. Try clicking your link above and it wont work. You have to search for the product by its cat number - the code on the end of the URL.
