I have a Linksys b wireless router and two Dlink cards. One is a b and the other is g. I just bought the g and saw that it was backwards compatible. I wanted to eventually updated to g for the obvious reason of network speed.
I've set up 128 bit encryption with a key. Not sure if this is WEP or WPA? I suspect WEP. Do I need a firewall or is this enough security to prevent someone from accessing the network? I have just set up file sharing so the two systems are accessible to anyone on the network.
