Well, I've done it, Brian, I got the Netgear AC1200 WiFi USB Adapter and then I had every possible thing go wrong during the attempt at installation, so much so that for a while Netgear Tech Support was even stymied!
I'll give you a very brief synopsis of what happened-- just because it may amuse you to see the number and variety of things that can go awry during what should be a simple and straightforward installation process! And then, if you don't mind, I have several very important questions for you that Randy, the Netgear tech support fellow (new to his job, I gather), was clearly unsure of the answers to. But you, as an experienced user of wireless adapters may well be able to handle them much more readily.
So, no sooner did I insert the Netgear Resource CD into my optical drive (which I very rarely have used on this computer) than things went off the prescribed path!, My optical drive didn't automatically start when I closed the drawer- only several minutes later, when I opened the Charms Bar, did I hear the optical drive suddenly whir into action. But even then, the Display Page of the Resource CD didn't open, so I had to click on Autorun.exe. Then, at the very earliest stage of the Setup--where I clicked on check for Updates, and they said it would take up to 30 seconds-- the entire installation process came to a complete halt. Instead of completing the Update process, and then going on to the next step, nothing further happened whatsoever. I could hear the optical drive stop whirring-- which I took as an ominous sign. Eventually-- after waiting through about 10 minutes of absolute deadness-- not knowing what else to do, I clicked 'Quit' on the Setup page. So, that phase of the installation process not only resulted in no installation of the Netgear adapter, but the bonus of having the Netgear Resource CD get stuck in my optical drive, where it remains at this moment!!!!! Not surprisingly, given all these untoward events, I see no icon anywhere on my computer indicating that my computer recognizes that there's a CD in the optical drive!!
Reaching that dead end, I felt compelled to go through the elaborate process Netgear requires to make sure they only give telephone Tech support to customers who deserve to have it.
Finally getting to Tech Support, I spent at least an hour on the phone with the newly-on-the-job tech support fellow, Randy, who took me on many wrong turns that forced him to retrace his steps (in fact, he was so discombobulated at one point that he had me abandon the Chrome browser and start all over again, right from the beginning, in Firefox!), but eventually we successfully installed the Windows Standalone Driver, and got the Adapter accepted into my wireless network via the WPS button.
But, here are my questions, britechguy: At first, Randy, the Netgear Tech Support fellow, said that if I ever removed the Netgear adapter from my computer I would have to repeat the WPS procedure to get it accepted on my wireless network again. When I pointed out that I turned off my computer at the end of every day, and turned it on the next, and if I removed the adapter while it was off and re-inserted it before I turned the computer on again, the computer wouldn't know that I'd ever removed the adapter. When I pointed that out, Randy amended his statement about not removing the adapter to say that I couldn't remove it while the computer was on without having to go through the WPS process again, and if I turned on the computer without the adapter already inserted, I would also have to go through the WPS process. But I questioned even that, because my computer's internal wireless system (when it was still working!) just had to be connected once, and thereafter it connected automatically. And I could turn the WiFi on an off without having to use WPS to reconnect with the system. But I'm really unsure about all this, there could be differences between the way my computer handles its own internal wifi system and how it deals with the Netgear adapter-- so I ask you britechguy, am I free to plug and unplug the Netgear adapter in the USB port as I please, whether the computer is on or off, and have it be automatically recognized and connected to the Wifi, or will I, under certain circumstances, have to use the WPS buttons on both the Netgear adapter and my router in order to reconnect?
Of course, I still have to deal with the CD stuck in my optical drive, but that's for another day!
