I just bought a DIR-655 to replace the unstable wireless functionality in my U-Verse 3801 RG. I have it set up in a simple AP fashion - 655 has static IP in same network as RG, DHCP is off on the 655, wireless off on the RG, 655 attached via LAN port - 655 Internet port is empty. So basically the 655 is acting as a wireless AP and switch on its 4 LAN ports.
The problem is with U-Verse TV signals going through the 655. When I change channels on a TV, the picture and sound last 10-13 seconds before locking up and the STB complains about loss of TV signal. A workaround is to route the TV signals through an old Netgear switch (actually a router being used as a switch) and simply jumper the 655 into that switch from one of its LAN ports with no other devices hooked to the 655.
I've tried enabling Multicast, disabling everything in sight (QOS, etc.) and even upgrading firmware to 2.03NA without success. Can anyone help identify the 655 setting that is shutting down the TV signal after 10-13 seconds?
Thank you,
Scott
