Hi, upgrade your Netgear DG834G v3 router to the latest Version 4.01.28 for UK only. Don�t know if it will give you WPA2 though, I could not see any reference to it.

I use, wireless security WPA-PSK TKIP with the 63-character password that I cannot remember, and the wireless broadcast SSID Mickey Mouse, and have changed the third and fourth octets, from the router default IP address.

Static IP address setup converting from a DHCP based LAN configuration.

How do I change my router's IP address?
