We are running with four AP541N in a cluster (connected to a SA540), where they all broadcast on the same SSID and channel (9). If we forces one offline by unplugging the power, a client is automatically connected to another AP in the cluster. But we have a few questions:
1) For testing purpose, is it possible from Vista/Win7/XP to force connection onto a specific AP in the cluster? Only one network is shown in the list, and the AP with best signal seems to be the one automatically choosen.
2) One problem we have found is that two of the APs have a WDS connection between them (one is at a location where we could not easily cable it). This also seems to basically work fine with clustering, but if the wired part of the WDS goes offline, the clients already connected to the wireless WDS AP does not get kicked out, but do of course loose their connection to the network. Even worse, clients connected to the wired WDS AP (which "went down"), might be transferred to the wireless AP with no network connection since the signal from this might be the best...! Any way to solve this, so that APs depending on the WDS kicks out their clients if the WDS is broken....?
We do also seem to be biten by the "speed degrade" issue of the APA541N now-and-then, particulary on the AP beeing the wired part of the WDS. Using WPA-PSK, and having set the recommended "key refresh" setting to 0, without seeming to help anything at all. Running FW 1.8.0, and really hoping for a new FW fixing this issue to appear soon!
