Problem with Belkin play poweline adapters
 

I'm having some trouble with my Belkin powerline adapters. I recently upgraded to them to improve the speed over the 200mbps ones I had before whig stopped working. If I plug my computer directly into the adapter it's fine, however I have a second router in this room so I can get wireless in there and thats where the problem is. I can't get a wireless connection now.

Aside from the adapters nothing has changed from the previous setup so theoretically it should work, however I went through the whole setup process on the routers again to be sure but no luck. If I plug an ethernet cable into the second router it does connect and my computer will connect wirelessly to the router but it doesn't get an internet connection.

Is there something I need to do to the adapters to get them to work in this way? I haven't done any setup, just plugged them in.

The adapters are called belkin play gigabit powerline adapters

Thanks in advance
