A customer of mine have previously had 2 AP1242 set up as root-AP and then an additional AP1252 set up as WGB onboard a (very slow) moving vehicle. This has worked very good.
On the vehicle there is 1 "real" PC and 3-4 additional PLCs or such "dumb" equipments with an static IP-address each. All equipment on the vehicle is connected to an unmanaged Layer2-switch.
Now they have extended the WLAN-installation, and replacing the 2 old and added 5 new APs (all lightweight) and a WLC. The vehicle-WGB is also replaced. All new APs and the new WGB is AP2602 and the WLC is a 2504.
After installing the new CAP2602, the WLC2504 ande the new WGB AP2602 on the vehicle they report that the roaming is too slow for the application that controls the vehicle..... TYhis results in a "Full Stop". Which is rather undesirable!!
I have looked at the configuration of the WGB-AP which is (in principle) unchanged from the AP1252 and also the WLC, But do not see any peculiarities. We also tried to set the channel on all tyhe APs to the same (Meru-style...) but that did not help. The environment of the APs and the vehicle is absolutely guaranteed free from any other interfering WLANs/networks.
Any iseas? I attach the config of the WLC and the WGB.
Yes..... That one (WPA/AES) I overlooked when browsing the config file, I was convinced that I had set that up during install but obviously it was changed during customers own first "look-see".... :-(
I was on site yesterday afternoon and we changed that to the recommended setting (WPA/TKIP & WPA2/AES). I also ticked "Fast transistion". After a quick post-survey of the RF (which was not done "due to cost") I also killed all 11b-speeds and set lowest data-rate to 12Mbps.......
After this a test of the vehicle was performed and the WGB-client roamed without issues! Hurray... :-)
