We went to 25.14 when it was an SRC and the performance issues started happening. Support suggested we rollback to the previous firmware, however the performance issues persisted after rolling back to 25.13. When 25.14 became an official release we went back to it again hoping the issues that came when we went to it would clear up, but unfortunately they did not. This time the disappearing SSID issue has come up as well, but we only stayed on 25.14 when it was an SRC for less than a day, so it never had the chance to pop up if it was an issue in the SRC as well. So even if we roll back the performance issues persist, but the SSID issue will likely clear up. At this point it can't get much worse if we go with the 26.6 SRC, so I'm probably just going to give that a try.
