Upgrade went smoothly last night, looking good so far. Had a strange problem with one of my clients that had some network issues over the day. Currently even that one is running flawlessly. 😎
Been running 27.2 in a environment with mixed MR55 and MR56 over the last week.
Seems to be working fine, had a few issues where users seems to be still connected but unable to process traffic.
Sent pcap to Meraki, no answer yet.
Other than that is seems to be stable.
I still have the issue I had with 27.1 on an MR55 where Intel 802.11ac wireless adapters have appalling latency and drop packets when the laptop is on battery and the wireless adapter engages power saving mode. It does look connected so that may be what you are seeing?
