Hi there! I have just migrated my wireless network to controller-based. Coverage was not an issue when everything was in autonomous. Now that my access points are lightweight, I'm starting to see problems with regards to coverage. Two of my access points (on different locations) do not seem to propagate signal. Associating users are just probing and never get to connect. I'm still new to controller-based setup and I'm wondering if somebody could help me troubleshoot this problem. On one location, I had to install a standalone access point just to give wireless service back to the users.
