What sort of house is it Weaver & has it been extended? If so then when.
By that I mean wall construction etc.
The mandatory insulation stuff like celotex is sandwiched between two layers of metal which isn't great.
However if you're in Skye then the inevitable issues that more & more & more
5GHz wireless has won't affect you. The wails in urban areas in future years... meh
The Ubiquiti stuff I linked to works very well but after a couple of years you can hear noise from the unit - a bit like a hard drive sounds. That (IMHO) is due to the coolant they use in the passive heatsink - some chemical has reacted etc. They work fine but burble when traffic happens. Odd
Edit - if you do choose Ubiquiti stuff then IME they never have antenna on the network port side of the AP. The 3x3 array will be on the other sides.
