Hub 3 hot weather no Internet

Hi, during hot weather(25°+) my hub 3.0 led shows a steady red and the internet goes. It only comes back on when the weather/temp cools down.

This consistently happened every hot weather day the last few weeks. I've had my hub 3.0 about a decade now but this is my first time with this issue. 

Service status for my area always shows as good. I check all connections and reset everytime but it only works for a min then it goes again. The only thing that solves it is waiting for the weather to cool🙁. 

It's been in the same spot with lots of space around it for years without issue until now.
