Configure Netopia 2247 Router as Bridge

Hi,

I'm attempting to configure my Netopia router as a wireless bridge to use with my Slingbox but I cannot get it to work. (I've tested the Slingbox with a wired connection so definitely a bridge problem)

So far what I've done is as follows:
1. Selected the bridge mode option in the config page
2. Changed the IP address of the bridge to be different from main router (which is also a Netopia 2247).
3. Turned off security
Tested to see if Slingplayer can pick up Slingbox --> Didn't work
4. Changed the option from "PPP over Ethernet" to "RFC-1483 Bridged Ethernet"
5. Turned off uPNP and Firewall
Tested to see if Slingplayer can pick up Slingbox --> Still didn't work.

(I also can't ping the bridge from my laptop)

I'm out of ideas now...what am I doing wrong here? Is what I'm doing even possible?

Thanks a lot!
