Hi I hope someone can help us. I've only just joined Plusnet and have set up the router and connected to bb but when I open Internet Explorer PN doesn't come up, it opens AOL ( who I left 3 years ago ) and Yahoo windows...how do I get rid of them and just open PN?
I hope this makes sense as I'm not the best at explaining things in an understandable way

When you refer to Yahoo do you mean the Yahoo toolbar
If so this tells you how to remove it http://help.yahoo.com/l/us/yahoo/toolbar/toolbar8/general/general-07.html
With respect to AOL if you mean the AOL toolbar this explains how to remove it http://www.instant-registry-fixes.org/aol-uninstall-for-internet-explorer-and-firefox/
If you mean Internet Explorer first page is AOL then click on Tools, Internet Options and General gives you the option to change it to whatever you like - see picture
