Slow сlient roaming when HREAP used (local swithing)
We have standart wireless deployment with 24 APs (1240G model) and wireless controller 4402-25 placed on same site.
Most of clients (WMS RF terminals ) works with one WLAN (WPA2-PSK) and constantly roam over warehouse , and that works great.
But for better survivability(when controller dies) we are trying to configure HREAP on our APs with local swicthed local auth WLAN. And that also work , but client roaming occur much more slowly and RDP connection to WMS APP server sometimes stuck for 2-5 sec.
Disabling "local switching" checkbox for WLAN make roaming almost momental.
Is that normal behavior ? And slow roaming are price for controllerless HREAP design ? And for fast roaming and survivability we must use N+1 wlc?
Re: Slow сlient roaming when HREAP used (local swithing)
Local switching should be okay since the AP will be doing the encryp/decrypt when using PSK. How does the traffic flow? Does everything come back to where the wlc sits or not? What I would try to determine is if it's a certain application having issues, a certain device or just overall all devices roam slow.
