very important tip that boost my signal from 66 to 92 % instantly
place router with lights facing down and looking the router from left to right ,the first 2 antennas on the left straight up and the last one on the right,bend it one click to the right

either way you place the router or antennas you wont have any problems it just give you a very big boost on signal ..
now i dont have disconnects fully stable and during day time i get 28000 speeds wireless and @ night i get 30000 downloads and wired always 32000 here is the site i use »speedtest.cfl.rr.com/
