Hey modders, a few months ago I DIYed my own Windsurfer (Free Wifi Antenna Booster) google it if u dont know what's a windsurfer antenna made it from plastic sheet and some 1cm copper tape instead of pure paper.. I have 2x asus n12 with DD-WRT firmware and ONLY the router inside my room has the Windsurfer on it. The two routers are 15-20m apart, in between the two routers 3 wooden door, 1 concrete wall, 2 glass windows. I'm currently getting a signal quality of 40%, signal -62, noise -82, SNR 20 and the two routers are connecting at 104-117mbps constantly. Windsurfer works great. Since the router upstair is the main broadcaster for all wifi connections around the house (my room's one is a repeater bridge for myself only), I am not planning to put another windsurfer on it because it will make the data directional and not omni directional. I'm planning to get some higher quality sma antenna to replace the 2dbi default ones on asus n-12 router. Anyone has experience which antenna to get?
