Now, I don't know if this falls under hardware but since this started with installation of new hardware.
So, here's the problem:
My old wireless adapter card, which has lasted through 4 computers over 6 years finally crapped out. I went and bought a new ASUS PCE-N15 wireless-n adapter. Installed it, ran the install software. Re-entered the security key (not my personal network) and got a better connection than before. It says I am connected to the internet, but I can't download or access any webpages, except sporadically and briefly. I did a websearch on my phone here for any similar problems and their solutions. Pretty much every one I found was a virus scanner had accidentally removed neccessary files and to use a winsock fix. Since I am running Windows 7, I had to download a batch file. This didn't work, tried a couple other things, such as removing the the anti-virus, as well as the anti-spyware, et al. Finally culminating, in my frustration, in a re-install of the OS. Having finished that, and all other setup, I find myself with the problem remaining. Help?
