I'm truly baffled. Here's the deal...
Gaming PC is in the basement, plugged into this extender. I've got the Nighthawk router upstairs. It's worked fine for about a year. Neighbor cut our Comcast internet wire in the backyard when he was digging a trench. Comcast came and fixed it. All internet in the house was working fine afterward, except my PC in the basement. I tried EVERYTHING. Every forum post online, I tried it. Nothing. I installed Windows 10 on it, still nothing.
Then, I brought it upstairs, plugged it in directly to the router. Boom. Internet. I update the Adapter drivers. Seems good. But, the big test... I brought the extender upstairs, plugged it in and hooked the PC up to it. It works!!!! Yes! I was pumped. Finally, maybe it was driver issue or a Windows 7 issue... who cares, it's working.
That was until I took it back downstairs and plugged it in where it was. Back to nothing. WTF!!! It's all the same, just a different plug in the house. The plug works fine. It's the same plug that's powering my PC and a lamp. I'm seriously lost...
WTF could it be?
