Sorry, FJJP - I'm not techie enough to be of much help. I don't use WEP with my set up due to my location. Instead I rely upon MAC address restriction in my wireless modem. Thus it will only 'talk' to computers it's been told to accept. If some spotty geek really wants to suck the noughts and ones out of the weak W-LAN signal from my PC to read my PPRuNing......get yourself a better life!
