I miss a littel bit the Raspberry Pi 3 Support,
for WLAN USB Sticks and drivers.....
Config Examples for Dual band and so on....
Most Realtek Drivers i tryed to get working dosnt
anyone who works with OpenWRT on Raspberry Pi 3?
Some of the Ralink Drivers work in my case the 5370
others seem to have problems
Not wanting to contradict @slh, just adding:
There is also an active project to get a generic driver programmed for Realtek USB devices: https://github.com/torvalds/linux/tree/master/drivers/net/wireless/realtek/rtl8xxxu . Most recent changes were 2 months ago.
There seems to be code in there for RTL8192c, RTL8192e, RTL8173a, and RTL8173b for now.
This page on Wikidev with more info seems hopeful, but outdated: https://wikidevi.com/wiki/Rtl8xxxu, It also only list STA mode as "supported", the rest as "unknown".
rtl8xxxu exists, but doesn't cover all relevant chipset variants, as realtek is adding a handful new ones each year.
 although development focus is not on AP mode, nor can it quite compete in terms of performance. While development started strong, its pace seems to have stalled over the last 12-18 months.
