To extend the wireless range I bought a pair of powerlines. So one of them is connected to the main wireless router which is provided by ISP company. And the other side of the powerline is connected to a D-Link (DIR-615) wireless router.

The second router does not provide internet. Not even by Ethernet. I was told that I have to disable the DHCP on the second one. and enter the first's routers IP as the getway. I tried to do it but I requires the IP address and Subnet mask that the ISP provided. But I never had that.

So anyway can you just tell me how I can connect these two routers. Thanks.

I can't think of any valid reason to implement powerline IP in a professional environment. If you have encountered such an environment please update your question to explain why you need to implement this solution, and how it fits into a professional production environment. – voretaq7 Jul 2 '13 at 2:29

Since the second is simply relaying off of the first one, the IP/Subnet/Default Gateway would be stuff supplied by the first router. Give it an address outside of the scope DHCP can give, subnet should be the same that DHCP supplies, and Default Gateway would be the address of the first router.

Thanks for your post. What about primary DSN address? Screenshot – Kamran Jafari Jul 1 '13 at 21:01
You can use the same as your default gateway, as everything would be pushed through that router. You could also see what the primary router is being configured to use, and then copy that information, but then you would have to update it if your ISP ever changed their DNS servers. – Rhyss Jul 1 '13 at 21:05
Thanks. I connected to the primary router and changed the DHCP to so is its own ip and is for the new router. Is that correct? but in the new router I tired to setup internet connection. (see the attached screenshot is last comment please). So I put in the first box, in second and for the geteway and and the same for DNS. But it gives error and says invalid ip address, pointing to the first box. any idea? – Kamran Jafari Jul 1 '13 at 21:22
The primary should be left at It is the default gateway. The second should be setup with an IP of, subnet of (to match the primary), default gateway of, and a default DNS of Nothing should have to be changed on the primary in regards to DHCP/internal network settings. – Rhyss Jul 1 '13 at 22:33

I'm not quite sure how "a pair of powerlines" will "exted the wireless range" but I'm going on the assumption that you mean Ethernet cables, If this is incorrect please comment below.

If you are wanting to bridge the wireless signals (i.e. make two wireless access points appear as one) DDWRT may be a good solution to make your life easier. And there are several posts on how to use a router flashed with DDWRT to extend the wireless range of another.
