WEP and WPA/2 are security on the wireless routers
its to stop people using your wireless network .
i am with virgin media and on 10meg
they upgraded my speed from 4meg to 10meg for free but the set top box i had was not capable of supporting that speed so they sent me a separate modem
i then phoned there help line only to ask when the speed upgrade would be applied they told me the next day which it was but also another modem arrived in the post so i now have a spare modem
There is noway i am going to pay the price they are asking for the 50meg
for what i do 10meg is enough for me
