How warm is it at your place? I've been quite successful avoiding router lock ups by adding some active cooling: take an old PC fan, solder it to the power wires of an old USB cable, connect that cable to the router (assuming your router has an active USB port).

Taiwan: so hot right now. 32ºC in the day, 26ºC at night.

I've often speculated that the temperature is causing problems, which would also explain why it's hard to reproduce the issue when a telecom service tech comes over. I'll have a look around for a suitable fan, and see if that helps.

I did this on one of my APs that fails frequently (locks up and the front lights go off, signal strength randomly goes down to about 8 feet with no obstructions, etc) and it helped immensely. unfortunately, it didn't /solve/ the problem for me, just made it better. I've ordered some unifi stuff on recommendation from friends. hopefully that'll live up to the hype and do the job.
