but give us a make/model
the thing to remember is that wire is faster and more secure.
wireless is meant to be accessed .... so it's always open to grabs...
it realy depends on the circumstances ... in an area like mine ... no one owns a computer ... no need to get silly.
at work ... we tie down the open links ... with mac filtering
wep wap wpa psk .... it sounds secure - but none of it is realy ... 20 mins and i can open any router (I'm not good - it's just laughably easy if you have the right tools.)
wep is good enough under most circumstances ...
mac filtering makes it a little better ...
but the more you do - the more time your router spends decoding and encoding ... so in a busy resedential area ... your "up to" 8meg is almost impossible.
don't be paranoid ... stop the opportunist with wep .... and mac filtering
unless you are a bank ... why would anyone seriously try to access you??
