I didn't get much response in my other thread so I'll try to reprhase

How much distance are you supposed to get in reallife on a 7.4dbi omni with the RB/019 integrated AP/backhaul unit (atheros AR5213 card). And using 19dbi flatpanels as the CPE, with direct line-of-sight?
I currently get less than 500m. Noise floor in the omni is -79dbm. Signal in the CPE at 500m is -65dbm but it still does not want to associate......
is this normal? There are only 2 or 3 other APs in the area.
Thanks!
