So, this is for anyone who might have ANY idea on how to help me... I installed Windows 8 about 2 months ago, and except for one problem, the experience has been fantastic. The problem is that every so often (ranges from 2x a day to once or twice a week), my wifi connection stops connecting to the internet. I use a USB Netgear adapter, and I am using a beta Windows 8 driver (which nobody else seems to be having any problems with from reading support forums for the device. What happens is that I will suddenly lose active connection to the internet, though my connection icon looks identical. However, if I look at the adapter, its activity light is going crazy like I am downloading something huge. If I wait a couple minutes, the connection icon eventually pops up with the yellow warning sign that I have lost connection to the internet. At this point, I have two options. If I wait a couple minutes, the entire adapter will disappear from windows, and I have to physically unplug the usb key and then plug it back in and it reconnects and everything is fine again. Or, I unplug it and replug it in immediately. Sometimes this works fine, but other times the computer doesn't even recognize its gone and still says I have a network connection. If I then try to plug it back in, no lights turn on and I am eventually forced to completely restart the computer. Often this is accompanied by other USB devices I have starting to lose connection (like my mouse will just turn itself off, for example). At first I thought this was a bug with the USB wifi adapter itself, and figured I was stuck until Netgear released a better driver. However, the fact that my mouse was involved made me think that something else might be wrong. I went to my device manager and saw that there was a yellow warning sign next to the "Reneseas USB 3.0 eXtensible Host Controller - 0096 (Microsoft)". I uninstalled the device, restarted my computer and went back to the device manager, and Windows 8 picked up the device and it now said it was working properly. About a day later, the internet problem happened again. I went back to the device manager and once again it had the little yellow warning sign beside the USB 3.0 eXtensible host controller. I have to think whatever is going on here is related, but I cant seem to figure out what. Any ideas? If it matters, I am using an Asus M4A87TD EVO motherboard, with an AMD phenom chip and a 64 bit version of Windows 8.
