Android Device - No Internet Connection

All,

I have tracked down a problem with my wireless that is blocking my android devices from getting internet access.

I have the WD My Net N900 as a central router. Connected over cabled Ethernet is a repeater.

The Android devices can connect to the router. When they connect, the WIFI icon will be grey indicating no internet connection.

When the same devices connect to the repeater, they get internet access.

On the N900, if I set the DNS Proxy to on, then the devices will get internet access. If the DNS Proxy is off, they do not.

Here is my problem.

I want to keep the DNS Proxy off, so that OpenDNS works to provide content protection for my home internet.

Can someone recommend a work around or fix to get the Android devices connecting again to the internet through the N900?

Thanks in advance!
