Netgear USB Adapter Randomly Stops Working

So, I have a Netgear WNDA3100v2 wireless adapter that I use as the primary wireless driver for my home PC.  It's honestly been a pretty good card for the past year that I've had it.  However, lately it will randomly stop working.  It never did this in the past, but only started recently.  Firstly, it will randomly stop detecting any and all access points or wireless networks (there are a few wireless networks I can pick up other than my own, but I have my network set to a unique channel), and I'll have to unplug it, then plug it back in.  Secondly, it will work for anywhere between 1-2 weeks, and then it will just crap out, and I'll have to reinstall the driver.  I usually have to restart my PC as well before I install the driver.  I'll also have to get a fresh copy of the drivers (which I can do from my phone luckily) otherwise it won't work.  I've tried using the adapter with and without a usb extension cord, and with multiple versions of the driver, but it always craps out after a week or two.  I know this isn't a problem with the router, since my phone and macintosh have no issues with internet connectivity.  I was wondering if this was a common problem with the adapter, and if there was anyway to fix it.  Currently, I am running V2.2.0.3 of the driver for the adapter on Windows 8.1 Pro.  If any additionaly specs or info are needed, I'd be more than happy to give them.  Thanks for any help in advance :)
