Hi I have a ax3000 it seems to over heat and after it does that it keeps locking up and I have to wait a day for it to work , I leave it unplugged , I've updated to new firmware 1.07 I had a ac1900 that did the same thing while my old tplink n300 has no issues 

I've turned off 2.4ghz for now to see how that goes and also put it up on a stand for ventilation 

Any suggestions
