At home, I use 2 Mikrotik cAP lite devices to distribute wifi in my house with an ethernet network source (poe). I control them through CAPSMAN from a central Mikrotik router rb750gr3. Unfortunately, when I set up a second SSID as a virtual SSID, it becomes unstable. It can work well for days and suddenly problems arise, and devices cannot connect to them or cannot assign IP addresses to the devices. That is, the SSIDs appear and disappear from the air. I have tried all possible solutions I have seen on the internet, but none have worked yet.

Purchased in January 2022, its main use is as an AP for smart switches, which it manages relatively well since it only requires a few kbps. It was not extensively used with portable devices (laptop, mobile phones) as it is not its main purpose, but in the little usage it had, it never caused any problems.
In terms of range, I would only recommend it for relatively small spaces (20-40 square meters). Outside the house, when there is an obstacle like a second wall, it has issues, so I would only recommend it for 1-2 rooms with installation in the middle wall.
One problem it presented to me, which was difficult to identify since all the LED indicators seemed normal, is the Ethernet port, which after 5-6 months decided it didn't like the RJ-45 connectors, and I had to put a "spacer" under the plug to establish a good connection.
Apart from this issue, it has been working flawlessly 24/7 for a year and a half (except for power outages) without any disconnections from the network and the smart switches.
As for the setup, it is not terribly difficult despite having RouterOS, as the guide for default settings is more than sufficient for everyday use and can be done with basic networking knowledge. Even for someone who may struggle, there are plenty of guides on YouTube for setting up an AP with RouterOS for home use.

P.S. One great advantage I found in this AP and why I chose it for the smart switches is its size, which is slightly larger than a matchbox (approximately twice the size), so it can easily be concealed.

A reliable access point, but only for use by a few people. It was used in hotel rooms, due to its small size and the nature of the space, which did not allow for anything else to be installed (stone walls). It provided 100% access to all rooms. Unfortunately, it does not work well for use in a space with more than 10 people. It freezes due to its small processor. There was no need to restart the access points in the rooms, which means that its passive PoE injector is functioning correctly.
