At my marina, I have a routerboard 433 with 2 r52h PCI cards on a 10.0.0.0 subnet. running duel SSID, 1 secure with wpa 2 and one open. its set to 2ghzb/g/n 802.11 ap-bridge, with 2 ohmi antennas. Up close i get great signal with a 14mps down and 6mps up. 900 feet away i get 3 bars of signal with 2.3mps down and .56mps up. The 6 wireless ip cameras i have on the network have such slow speed. I'm concerned when more customers connect to the wireless the speeds will just be really bad. I'm pretty new to all this and im not sure what to do to increase the range, the penetration power and the speeds. At the marina every thing is pretty open with only a few 1 amd a half thin metal buildings. any help would be greatly appreciated.
