I am running a dlink 2100ap with a (30dBm) 1W signal amp to a 10 dbi antenna. I am having issues picking up the signal on my laptop, could it be possible that the amp is making the antenna broadcast at a higher frequency? (it operates in the 2.4 Ghz spectrum up to 2.5). How far should my antenna reach?
The amplifier doesn't change the frequency, just the power.
1 W + 10 dBi means in the directions the antenna transmits best, a receiver will see the same power as a 10 W ideal transmitter broadcasting omnidirectionally.
