I am with a wireless ISP (woosh) that has a little PPPoE modem and a directional antenna. I am recieving speeds nowhere near the advertised speeds although being in closish range of their tower. Is it possable to get one of them outdoor grid antennas with lots of gain to increase speed? Woosh operates on the 2100mhz frequency, would a 2400mhz grid antenna work?
