Question 1

does it work with windows 8.1 ?

Accepted Answer

I have a Mac maverick (10.9) & a CPU with Windows 8. The device works on both. I have not upgraded to windows 8.1, so I am unable to be certain about the device working on windows 8.1. To my knowledge, windows 8.1 just adds new features, so I think if it works on windows 8, it should work on windows 8.1.
Hope this helps

Question 2

I don't know enough...
I bought a yagi for concentrated signal but I need to connect it to something like a "wireless access point", I think.

I think I need to have a wireless access point to provide both wireless and LAN in the separate building that is ~150 yards from my wifi source.

Will this device or some other Hawking device do this for me?

Accepted Answer

Yeah you can use this adapter for that purpose. I recommend these 2 items be purchased with the adapter for maximum range and efficiency and fairly cheap. 
HAWKING HAI15SC Hi-Gain 15dBi Corner Antenna
HAWKING HSB2 Hi-Gain WiFi Signal Booster
If your trying to extend your WiFi you might be better off with one of the outdoor antennas though. Don't know your exact mission but if you need any further assistance feel free to ask.
