well the dwa-192 has great reviews, most test it out performs the competition but i don't know how accurate and real these tests are. also it's not too late for me to cancel this d-link adapter order, which usb based wireless adapter could meet my needs??Depends on your wireless client. As long as they have 3 channel ac than you have many choices.
I wouldnt recommend dlink, there are many better brands out there. Dlink adapters as i have seen are not reliable.
