I'm giving my son an Acer Travelmate C300 to use with an NTL/Virgin cable system. The cable will connect to a Netgear WGR614 Wireless cable Router/Firewall. Although the Netgear can handle wpa-psk the Acer can not. The choice seems to be between using WEP and using a netgear adapter to allow wpa-psk. As no high security activity (banking) will take place on this laptop - mainly e-mail and general sports surfing is wpa-psk really necessary. I know that WEP is weaker but wouldn't using a128-bit key length be sufficient ?
