Thank you.

Hello,
I purchased AVG Ultimate to ensure that my virus software was up to date on all the PCs in the family. Since installing my wireless settings have stopped working and so unable to access wifi on all laptops. I have had to use an Ethernet cable and now spent an age trying to fix. I have updated drivers on Dell website, uninstalled AVG and also uninstalled wireless software completely to no avail. Can someone please help as I am desperately trying to find a solution that will work, thanks 
Scott, Also in future, to keep everything together, please try to keep the whole conversation in one question/thread to speed up any resolution.
