Well I've set it up and it works fine apart from one thing.  After connecting the 'Windows Security' box shown below appeared, I typed 'admin' and 'password' as in the instructions and it directed to 'www.mywifiext.net' where I was told the installation was successful and I clicked the 'finish' button'.  Now, however every time I click on the IE icon in my taskbar to access the internet, I'm directed to 
www.mywifiext.net instead of my normal homepage bbc.co.uk/news.  I've checked internet options and it's still set as my home page but I can't seem to get rid of 
www.mywifiext.net.  Any thoughts?
TIA as always.
