    How do I keep neighbors from using my wireless internet. I have viewed
    wireless networks available and there are many with excellant signal. should I be concerned that others can access my wireless router

    Please give me some advice on how to take care of this

    yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    be very concerned becuase my neighbor has a open wireless network maybe its you :lol: but anyway i can do anything. i can hack into a website and they would trace it back to my neighbors ip and they would get a nice call from the fbi asking what is going on. use mac filter and wpa or wep but highly not recommened

    i think all you can do with that model is turn off SSID broadcast, turn on WEP, and turn on MAC address filtering to only allow your wireless card(s) access to the router. these are not perfect, but they will keep out most general "neighbors."

    The befw11s4 v4 supports WPA security with TKIP encryption, which is far better than WEP. If your adapter(s) support it, use it, if they don't, get a better adapter(s). Not broadcasting SSID offers zero additional security, and MAC address filtering isn't much better. You should also change your SSID to something other than the default.

    WPA will keep your wireless closed to most (if not all) of your neighbors, unless your LAN has already been comprimised and they're sniffing your packets already. ;)

    i think that is were you are wrong earthsound mac adress filter is pretty affective. yo can only spoof mac adress when you break the encyption

    MAC address filtering alone is worthless. MAC filtering + WEP is a tiny step above worthless. Breaking WEP encryption is a trivial matter these days. WPA + MAC filtering + non-default SSID is a much better route to wireless security.

    Since the original post was concerning the BEFW11S4, which supports WPA, assuming the poster has network card(s) that support WPA, that would be the best option to use.

    yes i agree with you all the way.
    but
    disabling the ssid does not do much it hurts you more than it helps you becuase since the clients can not see the ssid unless told so they have to recheck that the ap is still there. and this affects speed and link quality.

    of course WPA is best, but not everything supports it. if his does, great. if it doesn't, like my befw11s4, then wep and mac filtering and not broadcasting SSID are all we have to work with.

    I never said to disable the SSID, I said rename it something other than the default.

    joel1456 & curtmcgirt, what BEFW11S4 version do you have? Also, what firmware version? My BEFW11S4 v4, w/ firmware 1.50.14, supports WPA. OTOH, it appears versions 2/2.1/3/3.2 don't support WPA, although I'm not 100% sure about that.

    old. i think it's version 2; i'm not sure what firmware. the latest available for that version. i don't even use it for wireless anymore; i have a WRT54G and i use the befw11s4 just as a router. coincidentally, i can't use WPA on the WRT54G either since my girlfriend's version of mac OS X doesn't support it.
