I have a new client who is running three (3) BUFFALO AirStation HighPower N450 Gigabit Wireless Router - WZR-HP-G450H; one is configured as the router/firewall/AP and the other two are just configured as APs. All three of the APs are hard wired into the network via CAT5, thus, using a wired backhaul. The APs are not part of the WDS system. Rather, all three APs are setup independently with the same SSID and pass phrase, but all three have different channels - 4, 6, and 11. My clients uses a remote EHR system that they access via Citrix. Numerous times a day the Citrix session freezes and forces the users log out of and back into Citrix. Needless to say, this is both time consuming and frustrating for the client. Any ideas on how to remedy this situation?
