Hi All, 3 years ago I set up WRT310N as my primary router and WRT160N as Wireless Ethernet Bridge, both running the latest standard TomatoUSB from polarcloud (tomato-K26-1.28.9054MIPSR2-beta-Std.trx). This setup was running perfectly so far, but was getting old and I want to add additional features, so I decided to upgrade both routers to Asus RT-N66U. Both routers are revision B1 with 32MB flash (as reported by Tomato). I installed Shibby's Tomato build 119 (tomato-K26USB-1.28.RT-N5x-MIPSR2-119-AIO-64K.trx) on both and I set them up as follows: * Primary router: - 192.168.1.1 static IP - DHCP enabled: 192.168.1.100-192.168.1.149 - 2.4GHz enabled as AP, N only, 40Mhz, WEP2 Personal+AES - 5GHz enabled as AP (different SSID), N only, 40Mhz, WEP2 Personal+AES; - 1 static DHCP on 192.168.1.100 * Secondary router: - DHCP disabled - 2.4Ghz disabled - 5GHz set to Wireless Ethernet Bridge, Auto, WEP2 Personal+AES (same SSID and password as the primary router) - DNS: 192.168.1.1 (primary router's IP) - DHCP: 192.168.1.1 (primary router's IP) - Gateway: 192.168.1.1 (primary router's IP) - No static DHCPs I.e. the idea is to have the bridge over 5GHz and use the 2.4GHz for the wireless devices since most of them do not support 5Ghz. The setup is the same as I had before, except that the bridge is over 5Ghz. After I resolved some issues with my Windows network card (unrelated to the routers' setup), everything was running as expected and I was about to call it done, when, to my surprise, the connection to the secondary router disappeared! After some experimenting, it got even strange - it looks like the 5GHz radio on one or on both routers goes to sleep! I know that it sounds weird, but after some period of inactivity (looks like random period between 3 and 12 hours) the two routers disconnect, but after being pinged through the bridge for ~5 min., the connection is re-established and everything looks and works OK again. If I leave a client to ping a router through the bridge everything is running for more than 24 hours, i.e. it really looks that the bridge goes to sleep! BTW, I turned on my old secondary router (WRT 160N, moved to 192.168.1.4) and it connected and established a bridge over 2.4GHz without issues. The 2.4Ghz bridge disappeared once, but I wasn't able to reproduce it, so I guess that I was trying to ping it though the 5GHz bridge which was already asleep at that time. So, I'm at a total loss right now how to resolve this issue! I guess that I'm missing something and I would appreciate your help! Thank you!
