I found I had to download using a working PC then install the drivers from some CD/DVD/USB stick that I copied them to.
As to Wireless, get wired to see if that's the problem.
I have an older Dell Inspiron E1405 which required a clean install of XP & Svc Pack 3. I don't plan on using this on the internet very much (if at all) but IE 6 was included in the XP re-install, and I want to update drivers for the computer. My wireless board is working fine but I cannot reach any sites to download updates and drivers and such. When I type an address that has "https" address I always get "The Page Cannot be Displayed" pop-up and refers me to the security settings. I have tried changing them but always get the same result. I think this is caused by some settings but I cannot figure it out. Any help appreciated.
