wireless station; dhcp-client

If a mikrotik wireless station is using dhcp-client when it’s connected to an AP, and it disconnects and reconnects to another SSID, should DHCP release and renew automatically ? I’m finding that once a dhcp-client receives an address it doesn’t bother to invalidate it when the ssid changes, unlike an ethernet interface that loses link state. Is this normal?

:if ( ([/int wireless monitor wlan-2400mhz as-value]->“status”) != “connected-to-ess” ) do={ /ip dhcp-client renew wlan-2400mhz }

I’m having to use this script to make sure when I roam from home to the office I get the dhcp-client to release and renew the addy. Should dhcp-client see this interface down (!=connected-to-ess) and release it automatically ?

I’ve had that issue for a while now and not just with the betas. I wrote a script to renew when the interface is “connected-to-ess”.

Edit → I see you also use the same script! On a side note, release does the same as renew. Why?
