mu-comment man unta ko ani sa-una..., but since you seem needing replies..., I'll give my share..., but you may not like it
having one big powerful (range) wifi might be the solution!?..., pero..., ma-o ni ako tan-aw
'd powerful wifi' ========================
'your wifi devices' ========
as far as I can see with these equipment..., 'might' need equal terms?..., like..., for sure..., it can see wifi signal from a great distance..., but your device might not be able to send out your signal aswel!?, kung baga, the powerful wifi will have great send/receive signal and so should the endpoints.
and..., these so called long ranged (higher grade than residential) will have 3x, 4x, 5x or even a higher price tag
ang ako lang kay basin magmahay unya kag palit then ma-o ra gihapon outcome
better buy the regular wifi devices and 'place' them at "strategic" locations...
if you are not still convinced..., and if you still need that kind of device..., contact 'crx' here and/or call wiredsystems for your wifi needs...
