I had clean/custom install of Windows 7 in my Dell E520 PC. My dlink G520 pci wireless adapter was working fine with win XP Pro. But with Windows 7, there is no internet connection. Unfortunately, dlink does not have driver for win 7. Although win 7 installs its own driver for the network adapter, but it does not work. What should I do? Buying a new PCI wireless card with windows 7 driver only option? or can I use my existing dlink card with some tricks? Thanks.
