Problem started a few weeks ago. Not sure exactly if anything changed on my PC in terms of software. I know there have been no hardware changes. I am having horrible WiFi capabilities on my PC. Every other device in my household works perfectly fine. My PC is custom-built, running Windows 7 64-bit Home Premium. The BIOS and drivers are all updated. I was using a TP-Link USB WiFi adapter, which seemingly out of nowhere started running slowly. Then, the Internet would disconnect randomly and intermittently, or slow to almost a crawl. Since then, I ordered 2 more WiFi adapters (Panda and Linksys). All 3 adapters seem to work just fine on my laptop. All of them do the same thing on my PC. Oddly, the Linksys adapter worked beautifully for a couple minutes right after the installation. However, it eventually went back to horribly slow download speeds and/or intermittent connection. Nevertheless, I know the problem is not with the adapters, since they work fine on other machines. I have tried swapping out my keyboard, mouse, etc. with all of the available USB ports to no avail. The keyboard and mouse work fine in all of the USB ports, but the adapters don't work no matter what ports I use. Recently, I ran CCleaner, cleaned up the system and registry, did a fresh install of the WiFi adapter, and still it sucks (again, though, the adapter worked GREAT for a minute or two, then the connection pooped out). HELP??? Never seen this problem in all my years of building PC's.
