I have a router from my provider which is attached to the ADSL (phone) socket. The internal address of that router is

It hooks into a powerline adapter so that the rest of the house can access the internet, for example a server that I have. The server has address

Also attached to the router is another router with wifi. That router has address The wifi router has DHCP turned off.

Both routers have subnet mask

I am writing this from a laptop, which is attached to the network over the wifi router, and it has address

If I attempt to connect to the server (, from this laptop when its connected over wifi, I get no connection.

When I attach my laptop to the network using a cable and a powerline adapter, then I can connect to the server.

I can connect to the internet from both wifi connections (i.e. this laptop) and from the server (powerline network).

What could be the reason that the I can't connect to the server, when attaching to the network over wifi?

This "powerline adapter" - does it have a base-unit and several end-units, or only several identical units? Can you link to it's website? – aviv Feb 16 '13 at 18:14
They are all the same, from Zyxel. – Ant Kutschera Feb 16 '13 at 18:51

You need to make your WiFi router work as an AccessPoint. You should have this feature somewhere on your administrator page. I can't give you more details, as the settings may differ from one router to another. I think you should have the setup in the manual as well.

Now you have two different networks, with the same network addresses, one of the WiFi router, one of the main router and power-line adapter.

OK, I read the manual, and I also have to turn off upnp. RTFM :-) – Ant Kutschera Feb 16 '13 at 18:59
UPnP is not that of a deal, it might be useful one day. Anyway, the idea is that you don't want to use the second router as a router, but as an invisible extension to your existing network, and that was the AP does. – Radoo Feb 16 '13 at 19:02
I'll reboot it and see if it works... – Ant Kutschera Feb 16 '13 at 19:03
No joy. Might be that this wifi router is so old that it doesn't support being an access point... (circa 2005) – Ant Kutschera Feb 16 '13 at 19:41
Give me the name of your router. – Radoo Feb 16 '13 at 19:43
