I have a mature Windows home environment with Window XP, Windows Media Center, and Windows 7. All were previously networked with share files and printers. After installing AVG 2015 Free and AVG 2015 PAID versions on all Laptops/PCs my wireless networking was lost. Not printer sharing and no shared files … meaning networking was disabled or lost.
I have restart Network Set-up on ALL but does not work. Tried disabling AVG Firewall and Protection but no good. Also tried to UNINSTALL AVG and still can't repair or re-setup my Windows Network.
Everything was fine for years before installing AVG.
Please help.
Bob
