We setup an AP with RB333 having 3 wireless card on it. Each of the card is connected to sector each, b/4 this time the link was very fast when it was not been used by much people. I noticed the slowness of the link now as so many people are now connected to it.
I need a help on how i can secure the link from unauthorise users.
NOTE:We are transmitting on 2.4GHZ.
You need to read up on basic wireless concepts then read the manual to learn how to implement those basic concepts.
