I've had a similar problem before and I'm not really sure what the solution was although I think it MIGHT have something to do with ESET security software (firewall and antivirus). All my web pages are very slow to load, some sites like Yahoo mail is extremely slow. Plus any download I try from any site, will always stop at 99%. This includes trying to transfer/download files from my wireless LAN network (files from my laptop to main PC), they will also stop downloading right before they are completed.
I've tried disabling ESET, this does not help the page load time, and it SOMETIMES allows the files to be completely downloaded, but not all the time.
I've run a virus scan, malware scan, ran chkdsk, and defragged my hard drive.
Finally, the other three computers/laptops running from the same router are not experiencing any problems at all.
Thanks for any assistance!
Here are my specs:
AMD Phenom II X4 945 3.0GHz
8GB (4x2GB) PC10600 DDR3 1333 Dual Channel
ATI Radeon HD 5850
Windows 7 Professional 64-bit
Running ESET Smart Security version 4.0.467.0
