This is so frustrating. ANY firmware above factory 1.78 (including Asus and Merlin's) disconnects from my modem connection EVERY DAY. A re-connect attempt through the router settings FAILS and the only thing that works is to shut off my PC; power off the RT-N66U router; disconnect the power from my modem (SB 6121) and power everything up again starting with modem, Asus router then PC. When I go back to .178, this NEVER occurs. Anyone have any recommendations? Are there any "new" SETTING FEATURES in the latest firmwares that might be causing this? And if so, what is recommended to enable/disable in the RT-N66U gui? Thanks.
