Question/Answer from earlier this year on getting ASUS USB-AC53 network adapter running in Ubuntu
Where I am stalling out is that after using ButtersB's instructions Ubuntu is recognizing the driver and seeing my wireless network, but cannot seem to authenticate the WPA2-PSK [AES] security passcode. I believe I have the network connection settings set properly, and I definitely have the password and security type set properly, but it keeps asking me to re-enter the password rather than completing the connection. I tried to participate in that original thread, but I'm new here so of course I screwed that up (apologies for that).
That thread here is really the most useful thing I was able to find via Google on the topic so far. There is another top Google result for a link at this site here but those instructions for installing based on the chipset look like they're for PCI network adapters rather than USB, not the least of which as the ID's don't seem to match up from what I can see although if there's something I'm missing about that link I'd be happy to try things people thought might work.
If you check the top user reviews on the Amazon page for this product you'll see an Asus rep state that they are not planning on releasing a native Linux driver (assuming that information is still accurate, and in spite of the fact that they announced support for Linux right on the box) and they're blaming Broadcom.
So I come hat in hand to see if there is any hope. Thanks much for any information/advice.
