I have been using an IP3M-941W for a couple years now, it was outdoors.
One day it started doing a constant clicking noise. Long story short, I tried everything and its behaviour is now that it boots up fine, then reboots after 30m/1h. It works ok for that little time. I guess I will toss it in the garbage.
By the way, the forum has become utterly unusable: I get the cloudflare prompt every single page and half of the times it kicks me out.
