No sweat fella. It's a breeze. I'll dumb it down. Appologies if this is insulting, but you can skip the obvious bits.
As before, uninstall everything Tiscali/Speedtouch related as described earlier.
Connect the router to the filter/plug in power supply and plug an ethernet cable into any of the ports on the back of the router and the other end into the laptop.
Click on Start , Control panel and double click internet options. Click on conections tab.
There shoudl be NO connectiosn listed in the dial up box and the 'never dial a connection option should be selected and 'greyed' out.
Click on LAN settings. Make sure there is a tick in the first box only.
Close these windows.
Open internet explorer
In the address bar type the following address:
http://192.168.0.1
You will be prompted for a username and password. The username is 'admin' and the password is the word 'password'. please remove the quote '' marks . i.e. admin , password .
Click on Setup wizard
Follow the wizard through entering the tiscali username and password that Dad was given when he first signed up with Tiscali. Assuming of course he hasn't changed either of them.
This should now establish a connection, and you can shut the windows. Open Internet Explorer and you should connect.
If it does't connect, look at the router. Does it have a
green illuminated symbol that looks like a lower case letter i with a circle around it ?
Give us some feedback and we'll sort this no problem.
