Extend tether distance of phone(m7) to computer (approx 100')

I place my phone in a window at work for 4g reception. I used to use Foxfi to wirelessly connect to computer at my desk, latest lollipop update killed that option. Wondered about using usb to Ethernet adapter for an extended tether. Is there a way to tether my usb phone connection to my computer wirelessly??? Anybody can go out and buy a $750 signal repeater booster..........trying to do it as cheaply as possible..... Anybody have personal experiences or suggestions
thanks in advance
