EOC-3220 Radios keep dropping connection…

OK, here’s the deal, I have 4 wireless radios working together, kinda… First, I have 2 Zyxel G-5100 as my main two AP’s/Repeaters. On is called RV1 and the other is RV2. RV1 is hard wired to my Smoothwall router/firewall. The Zyxel G-5100’s have two radios in them. So, one radio is an AP, and the other is a Wireless Bridge to the other G-5100 radio. Then the two EOC-3220s are setup as Client-Bridges with Universal Wireless Repeater enabled. The two EOC’s are RV3 and RV4. They both connect wirelessly to RV2 (G-5100) and repeat that radio’s signal using the Universal Wireless Repeater option.

The problem is, for the longest time I had this connection working without any issues. Then all of the sudden earlier this summer RV3 and RV4 started to not communicate with RV2. But, now about a month ago, RV3 and RV4 started randomly dropping the connection to RV2. I mean, they’ll be connected for 40 minutes, or even an hour and 15 minutes, but hardly ever does the connection last longer. I was connected to the RV4 the other day, and about 46 minutes, it lost the connection to RV2. It just dropped. However, RV3 had been on for an hour and 17 minutes, and that connection dropped to RV2 also. But, if I logged into either radio, the status page showed that it was connected to RV2. And if I logged into RV2, it would show the MAC address of RV3 & RV4 in it’s association table. However, no communications between the radios. Unable to ping the radio from being connected to RV2, of if I was connected to RV4, I was unable to ping RV2 or the gateway, or anything.

If this was happening when the radio’s hit 45 minutes each time, this would be a little easier to figure out, but it happens at random times. I currently have one of my linux telneting into RV3 and RV4 to reboot the radios every half hour. It’s only a band aid right now until I can get an idea as to what’s causing this. I have also redone the firmware with older firmware’s and newer firmware. I have also brought the two eoc-3220 radios home and have had them connect to my d-link wireless ap and stay connected all day long without any drops. So, I know the issue has got to be somewhere in the park.
