Access points lose ip's & network connections.

[TrvTch]

Access points (msm 320 series) lose ip's & network connections when i unplug power cable or unplug lan cable of Access point controller MSM760.

I knew that access points have to work till their power or cable is unplagged. 

Can someone help me i can't solve this problem

It depends on how you've configured it. If the MSM760 is the DHCP server and default gateway for the AP320s then of course they'll loose connection if you disconnect the MSM760. 

There is also an option on whether to disable a VSC if the connection to the controller are lost or not.

Gateway is not controller and i don't use msm760s dhcp. 

The last thing is to check vsc option ?
