Hi All
My office have bought 3 AP AIR-AP1852E-S-K9.
I did configure AP1 to mode: AP & Controller with ME controller IP 10.155.241.5 - AP1 10.155.241.6
AP2 and AP3 to mode : AP only with AP2: 10.155.241.7, AP3: 10.51.241.8
In LAN, we only use static IP without any DHCP server.
After I finish, all are OK.
But whenever if any users accidentally plug new wireless router/modem (as TP-Link) or any equipment has DHCP-server function to LAN, AP2 and AP3 immediately change to DHCP (192.168.1.x/24), and so lost connection ME.
I have to found and unplug the DHCP-server quipment out of LAN, and reboot AP2 and AP3, after rebooting AP2 and AP3 back to static IPs (10.155.241.7-8).
But if any one connect DHCP-server again to LAN, the issue occurs again.
I did try Mobility Express OS 8.2.130 and 8.3.102 on all 3 APs but cannot resolve issue.
Please advise us if this is bug of ME OS or the configuration? Thank you very much.
