I'm having issues with a wm3400 controller. Yesterday and today again we received information from a customer having problems navigating through a wireless network consisting of a wm3400 controller and 6 ap's distributed in three floors.
Our customer informed me that he wasn't able to navigate the internet from any of the 6 ap's. The laptop/mobile connected succesfully to the network and the ip address given was correct, but he had no internet connectivity.
I checked the controller for logs but couldn't find any helpful ones, there was no un-adoption of AP's or disruption in the wlan's as far as I could see. Yet here's the strange thing (to me at least): reloading one of the ap's (being un-adopted and re-adopted), brought the internet connectivity back.
Our customer informed us that the procedure he followed to check that there was no internet connectivity was to connect via CLI to the controller and ping 18.104.22.168 and had no answer(packets lost).
What could be happening here? Congestion in the controller? How come rebooting 1 single ap brings the connectivity back?
Thanks in advance!
