I want to ask if its possible router dies wiithin 3 years just because it might be running hot in a room where there is no air flow and its hot and humid?
Is there any way to check the tempratures of the router

I saw this info on SNB Forums.  I tried it on my 3 AiMesh that I manage, 2 of 3 gave meaningful results, the other one (a BE router) did not.

You may want to try Merlin firmware to see it on this model...
