I'd like to extend my home wifi to my detached garage. I have decent signal outside the building, about 100' & 2 walls from the home wireless transmitter. But now that I've put the steel siding up, I get nothing inside. I'm thinking of mounting a high gain antenna like this: HAWKING HAO14SDP Hi-Gain 14dBi Outdoor Directional Antenna Kit on the outside of the building.
And then running the cable through the wall to some sort of repeater/extender/wireless access point. But I'm not sure exactly what I need for the inside. Maybe something like this: HAWKING HWREN2 Hi-Gain Wireless-300N Range Extender Pro, but take off one of the antennas and connect it to the external directional antenna?
It would be nice to have something wall or ceiling mounted, but I haven't found something like that with an external antenna connection. Shop area totals about 1000ft^2.
edit: This looks like exactly what I need, but pricey, especially till I by the $70 outdoor antenna. Hawking Technology HAW2R1 Hi-Gain Wireless-300N Smart Repeater Pro
What about Powerline Networking? Bear in mind, this would have to go through 1 or 2 subpanels, and some stuff I'll be using in the garage tends to be pretty electrically noisy.
