Mornng all!
Now that the model of the modem is now known we can progress further.
Helina's provider (Orange) have provided a complete set up guide on their website.
http://help.orange.co.uk/orangeuk/support/personal/461589After reading the instructions I would print out for future, bearing in mind the setting up consists of 2 parts.
1) Checking that wired connection works and settings correct.
2) Wireless set up (at the bottom of wired set up page, click on wireless settings)
So with your 'yellow' wire connecting modem to laptop follow instuctions to the letter.
(Diagrams are provided to confirm boxes to be ticked/information to be entered)
Suggest you take a break after doing wired connection confirmation.
I will check back later this evening, some of us work odd hours inc Sunday.
