@kenwsf Have you thought you might be better served using an Ethernet cable, or a pair of Powerline units to provide internet access to your hack?
Maybe running an ethernet cable isn't feasible where you live. However, the alternative Powerline units are much better than WiFi, if the router is some distance from the Hack.
My son used numerous Powerline kits when he was at University, as he had the same issue, weak WiFi in his bedroom(s) where his MBP and Hack were located. He used a number of kits as he kept giving the kits to his girl friends each time he moved house, didn't matter to him as I was paying for them!
Something like the TP-Link TL-PA717 Kit might solve your issues. These starter kits cost round £30 in the UK.

You can also get PowerLine kits that include WiFi capabilities, but they tend to cost more than the Wired only kits. Also the current units have limited WiFi capabilities (n).

TP-Link have a couple of newer kits 'coming soon' that are supposed to provide much faster WiFi speeds.

The Pass-through kits/units cost more again, as they allow you to pass the electrical current through the unit to serve another device from the same electrical socket.
