T46G WiFi cannot access web gui

[SimpleCom]

Okay. I got rid of the stock firmware on my router and flashed it to something (hopefully) more stable. Only one wireless network, no guests or anything. The phone comes up just fine on DHCP via Wifi. Calls work, display works. Cool. Still can't get to the web gui via the wifi dongle. The phone's address shows up in the dhcp clients table. I'm at a loss here. I tried giving it a static address. No joy. Something strange here. I wonder if it's something to do with the .53 firmware I put on the phone. That release allows better control over the power LED. I have clients that want their phones to go 100% dark at night, and Yealink sent me this firmware. They say it's tested and stable. I'll try going back to .50 and see what happens. It's the only thing I can think of.

Anyone else got any thoughts on this?
