I have a lab set up involving AP and DHCP, I am using my Macbook to connect to the AP and it requests a DHCP lease, however, when I change the network information on the router, the Macbook still keeps the obsolete information and has connectivity issues regarding the Internet.
I have been removing the network manually and this seems to clear the cache and accepts the new lease.
This is too time consuming though, is there a quicker way to clear the cache/lease so it can request a new address without having to 'forget' the network every time?
