We had a bad batch of them right at the end of their availability but they failed very early and completely. We have had a few hAP ac lite’s (RB952Ui-5ac2nD-TC) loose their wlan2 interfaces over the years. Sometimes they would come back after a reboot or a power outage sometimes it was permanent. I never thought to replace the power supplies but then again where we took them out of service I don’t recall any of them ever getting "better”. I do have a couple that have required a Netinstall because they ended up with completely corrupted RouterOS and they were getting PoE from Mikrotik CRS3xx switches so power shouldn’t be an issue. Both of those are now in the “untrusted” drawer. At 4 1/2 years old it sounds a lot like a electrolytic capacitor on the power supply circuit… Good luck.

HI all,
Kinda pulling my hair out with this one.. Hoping someone has a suggestion. I have a RBwAPG-5HacT2HnD, love this thing. But yesterday morning we started getting weird outage alerts from monitoring at home, with some devices being offline. (The main kicker was the cubby lol) When I got home from work I went looking, and finally tracked it down to wlan2 being missing.. A reboot brought it back.. But 10 mins later it was gone again. Rebooted it a few more times, then added remote syslog, and went to bed. Got up this morning, and remote syslog really wasn't any use at all (I assume there's some specific prefix I should have been punting to remote syslog to catch the device going away), and now reboots aren't helping, it has to be a physical power removal and re-application..
Thankfully I have a spare (Got one on ebay at the start of the year, and had meant to set it up at the back of the house), so have just finished copying the config to it, but would love to get this one working properly again.. Was hoping it was just mini-PCIe cards or something, but alas no.
Has anyone had the 5GHz radio go away on these? And fixed it? It's 4 1/2 years old, so I'm pretty sure it's out of warranty period 🤣
Thanks,
DG
