I was running version 4.2.130 on 3 wism blades. Actually one of the controllers in one wism is running a mesh code, so i did not upgrade it. Upgraded all except one (cause it won't upgrade, thats another battle) to 220.127.116.11. And now the controllers randomly go offline for just a few seconds, just long enough for the waps to disassociate. This probably happens twice a day, but it does not happen on the one that is still running 18.104.22.168 and the one that is running the mesh code. I'm not sure whats going on, I looked through the release notes to see if there was anything that may cause this, but I didn't see any red flags. Anyone have a clue as to what may be going on here? Any help would be appreciated.
