text: wireless network security? i just bought the linksys wirless - g broadband router with speed boost and the the linksys wireless - g usb netwrok adaptor with speed booster. i treied to add security to the network, but it did not work, saying that the adaptor could not communicate with the router. it only worked if there was no security on either the roter or adaptor. so, i finally got it working with just wep security, yet there is a stronger security available, namely psk and wpa. so, if wep is not the strongest security available, what can i do to make the network more secure and stop people jumping on to mine?   i am using a laptop as the main comp. i am running xp service pack 2 on it. i have the ability to set mac address filtering, (but i don't not know my mac address, how can i find this out?) i can set a passphrase but trying this stopped the network from working.  any ideas? firstly the mac filter will not keep out anyone who is into spoofing.  but to learn your mac number, open a command window  and type  getmac   wep is pretty easy to break these days.  wpa is much stronger [for the moment].  george ou wrote a great article on wireless security at http://blogs.zdnet.com/ou/index.php?p=43
