Hello, I have a mikrotik cAP ac, for a long time it worked without problems, however a couple of days ago I got a problem. The access point works from 10 minutes to half an hour, then it just gets stuck (can’t access by ip or MAC). But the eth1 LED blinks (connected through it) and the power LED is on all the time. To successfully boot the access point I have to switch it off for a while. Then it works for a while and then gets stuck again. I have already tried to install empty routeros via netinstall. I installed 7.15.3 Stable and 6.49.13 Long-term, but the result is same. However, I think that even though the AP is not detected through winbox, technically it works because the power LED is lit, the network interface LED is blinking, and the log after another boot has only logs about power failure (instead of kernel errors). Can anyone help me to fix this, or should I buy a new access point? Thanks to everyone.
How long in weeks/months is “long time”? The way you describe it it looks like an overheating problem, but in general, the first thing to degrade always used to be the electrolytic capacitors in the power adaptors (nothing specific to Mikrotik), so if you can try a newer one which matches the cAP ac requirements, or a PoE injector with an embedded power adaptor, I would start from there. The higher temperature may still have an impact in combination with the degraded supply voltage filtering capability of the adaptor. But if that does not help, I’m afraid there is nothing more you could fix.
For a long time this is about the last six months of running without rebooting at all. Before that (about 4 years) the work was also stable
As for the power supply I thought so too, for the last 2-3 years ap has been running from a poe switch and I have tried changing ports and using with the adapter and power supply from the kit and the behaviour persists. I have also tried changing the ethernet cable. After the problem occurred I also replaced the thermal paste and tried using the ap without the top part of case, all without results. Well, it seems it’s time to switch to ax
Given the above, I agree with the below.
My 0.02€ …
cAP AC is still being sold (just bought 8 for a new setup with a customer) and you can load wave2 drivers on them. I prefer the square package they come with over the round one. Fabulous decision from Mikrotik to have both in the box.
cAP AX is more performant, absolutely no doubt there, but it’s … HUGE for low ceiling setups.
I mean, I installed 15 of them in a warehouse setup, no problem there when they are 5m high.
But when you go to normal height environments, they really stand out.
That same environment also has 2 cAP AX in separate meeting rooms and they are pretty visible when you enter.
So you may also consider a simple swap with a new device, same model.
