Best Wifi desktop usb to use with new Orbi

I'm in a room next to garage that has firewall (actual wall, not network), what's the best recommended way, besides running a cable to master bedroom where the IDF is, but the wife won't allow a cable going up and down the wall, anyway, do you recommend USB wifi on the PC or should I get a Powerline, if so, which one?  I have used the power ethernet before, and had lots of problems with drop offs, no connectivity, etc.  I just purchase an Orbi because I heard it could cover 3000 sq house.  Current speed is 43.55mbps down and 9.51 upload.  I was told that the linksys can do over 300 mbps with this model.  haven't seen that yet.

Please advise

Thank you
