IP address change without control

Hi,

I use Router Mikrotik RB750GL.
I have many Ubiquiti antenna setted with static IP address.
98% of those work very good but I see strange behavior from couple of week.

into the picture I join, you can see the yellow line with field
address : 192.168.4.145 and ‘To Address’ : 192.168.1.147
the good ip address must be 192.168.1.147
and this antenna (is a router) has network address 192.168.4.0
http://forum.mikrotik.com/download/file.php?mode=view&id=8456

If you see same kind of antenna (line green) just 1 line up (192.168.1.146) the
field address and ‘to address’ is same.
(these 2 antenna has same config and are same kind of antenna NanoBridge25)

by the way, the only antenna is have problem to login is it (192.168.1.147).

Other point, some time, the ip address return correct like the green line.
Do you have idea why this happen?

thanks

do you have universal client enabled?

I use routeos-mipsbe v5.6 on RB750GL.

I try to found the universal client but nothing.
do you know where I can find information about that?

I do command ‘export file=fg’ and try to found some info on universal client into this backup. but nothing.

So, I don’t know if it is enable or not.

Make sure “address pool” is set to “none” in hotspot server

good, I do that and this help to make more stable IP, and I found into UBIQUITY antenna the option ‘Enable Mcast Routing:’ and when I put it disable. this help to keep same IP (Address and To Address fields).

but the last 3 AP (home router) as again the same problem. the Address field is good but the ‘To Address’ is different.
and the status into tabs ‘Hosts’ is ‘A’.
into DHCP sercer tabs leases, I see these 3 IP are ‘bound’ (status).

Why I don’t see status ‘AH’ into tabs Hotspot->‘Hosts’ for these IP
and why the ‘To Address’ is not same.

Note: when I put the home router (client) not static IP but Dynamic IP, the bug with address ip change by 209.85.145.188, seem to be resolve. I don’t understand why?

thanks.
