AT&T 640XL drops Wi-Fi on W10 builds

I am on insider production preview. My Wi-Fi randomly drops connection resulting in excessive cellular data usage. It's done this since the W10 update and on all builds even after WPRT back to 8.1. Is this firmware related?

Yes, it drops at home and work. Sometimes it drops quickly...other times it may stay connected for hours.

it could be the signal strength isn't strong enough - for peace of mind you could send it for checking but do you have warranty?
