for years my neighbors have been trying to get access to my Wi-Fi in 2003 they had cracked my WEP key back then my wireless router only supported WEP. I ended up disableing the wireless mode and wired the computer that was wireless. when I did this my neighbors got mad saying that I had no right to dissconnect them when I replaced the wireless router with one that supported WPA my neighbors asked for the key several times. when i got a laptop computer I always got knocked of my Wi-fi several times a day. I did have my WPA key cracked twice one day I had the wireless card and routers Wi-Fi part stopped working i had to set up a wireless access point that I had laying around I ended up setting up a RADIUS server and set my Wi-Fi for WPA- enterprise Protected EAP (PEAP) when someone tryes to connect the RADIUS server it logged the mac address of the computer or devices that tryed to connect sill had the problem of my Wi-Fi dropping connection. In 2011 I had people that I never seen before knocked on my door asking for the security code to my access point I ended switching to 802.11A with WPA - Enterprise I swiched to the 5 Ghz band I am having less problems.

802.11g works better where I live. When I set to b/g i constantly get kicked, I even tried 802.11b only there is alot of 802.11b access points near me. My neighbors has a 802.11b access point causes me to drop. I have a wireless router on ch. 11 and a access point set to ch. 1 both are set to 802.11g only with diffrent SSID. and WPA2 keys I have 3 meg dsl works fine under heavy load. When I set to b/g and b only I find an duplicate SSIDs because someone is runing a 802.11b repeater.
