I am trying to setup a large area wifi system using the EnGenius ENH202v2. I am using WDS AP mode. One of the devices is connected to a modem to the internet. All of the devices are configured identically with the only difference being the WDS target list excluding the devices own MAC. The "Base" device remains connected to the Internet at all times, however each of the other three "Satelite devices lose their links and break their internet connectivity. Recycling the "Base" unit's power restores the entire system's connectivity until one or more of the "Satelite" units disconnect randomly at some later time. Any idea what is going on?
