Put a password on my 3Com router

Hi, start internet explorer (blue e) in the address bar type 192.168.1.1 and press enter
in the new screen, type in the password to enter the set jup (as it says, admin is the default)
click wireless settings on the left hand side of the screen, click encryption, select wpa-psk from the drop down boxwhere it says pre-shared key, type in a MEMORABLE password and then click apply. Now you will lose your wireless signal. Panic ye not! Click on the smatt TV in the lower right hand side of the screen (this is called the sys-tray) you will now see that the wireless icon which looks a bit like a telly eith 3 yellow arcs coming out of it's right hand side has a red cross on it. Click it once, click view wireless networks and then on the new screen click refresh network list. You will after a few seconds see your network -click on it and then on connect. A new box will come up asking you for the networe key aka password. Enter the memorable password you have just forgotten in the upper and lower boxes and press enter. Et voila! you now have an encrypted wireless network and you can only get onto it if you know the memorable password! Have fun
