Let's try a few things here.

1. Read our forum sticky about what does work.
2. Read about POST 17 in our forum sticky about how to configure a router as a WAP.
3. Think about the firewall in the router and try setting it to only allow PORT 80 traffic. That locks these connections to WEB content only. It also cures an issue with freeloaders using it for TORRENT connections.

And please consider that the forum sticky is the top post in this forum. We put it there so you can find out the most asked questions without having to ask.
