User posts about low-quality Realtek device delivering low-quality performance. LE staff feign surprise and advise user that the $2 USB wireless thing they purchased is garbage. User asks for officially supported and recomended alternative cheap USB wireless devices. LE staff refuse to recommend anything because all the cheap USB wireless stuff you can find is similar garbage. LE staff recommend a wireless bridge that presents Ethernet to the RPi2. User protests that $20 (for a used Apple A1rport express on eBay) is an outrageous idea and makes pithy comments about our decision to not add more low-quality realtek drivers to our distro (so they can purchase the latest expensive USB Realtek wireless garbage instead of older cheap garbage). Eventually user gives up and gets a wireless bridge that just works and the pithy comments stop.
