I am going to post my setup first:
OS: Windows 7 Ultimate x64 (Completely Updated)
ISP: Comcast Cable
Modem: Motorola SURFboard 5101
Router: Linksys WRT300N (Latest Firmware)
Range Extender: Linksys WRE54G (Latest Firmware)
Question: I can browse the internet and do everything I need to do online, ONLY in Internet Explorer 64-bit. NO 32-bit apps will successfully use the net at all.
*I can ping any and everything under the sun.
*Absolutely nothing wrong with DNS.
*I've tried resetting the WinSock (netsh winsock reset), as well as all the other logical WinSock resets in Command Prompt.
*I've browsed multiple forums, to no avail.
*I've ran complete system scans with Avira and AVG, both Premium versions.
I have ran out of options. I've been working on PC's now for over 11 years, and I am stumped. It's not the first time, but I'm just clueless. Please help.
Some additional info:
1st) Google Chrome, IE 32-bit, Bittorrent, Firefox... ALL 32-bit internet-using-at-all apps can't access internet.
2nd) I've been running this same exact setup for a long time, and this problem arose last night. Out of nowhere.
3rd) Yes I have a software firewall, ZoneAlarm. Disabling or shutting it down doesn't make a difference.
4th) Anti-virus apps can't update.
5th) I don't even use IE at all, I was just trying to see if I could narrow it down to x86 or x64. It seems to be x86.
BTW, I keep a **constant** watchful eye on my posts, so I'm more than likely to answer fairly quickly until I get this problem straightened out.
