Bug report - DNS server

Hello everyone.

The past week after updating, I could not get consistent wifi connectivity through the BB2.   

There is a new option to use custom DNS servers.  I clicked it on once, then off since I wanted to use the DNS servers sent from my cable modem.

When I tried to connect to the SSID on the BB2, I would get an appropriate IP address and great signal but couldn't not go to any websites.

Even though the switch for custom DNS servers is off, the DNS functionality was broken.

By adding custom DNS servers, the problem is solved but it is not receiving DNS information from the upstream router (DHCP server).
