Hi, I'm trying to compile driver for RTL8189ES for the OPi R1 board. I've used patch from Hauke Mehrtens and latest git distro. All compiles well, but the wifi works only in scan mode. When tried to enable AP, the wlan0 disappears for ever. It's not available even after hard reset. All modules are persistent.
Any ideas what may be wrong?
I did, but no response. Therefor I opened topic here.
Some more details to the topic. This is the system log related to the wifi:

For those who are interrested in the topic on non working WiFi dongles, this is what I've found:
- Utility iw exclusively uses the nl80211 interface.
- some drivers, like RTL8188EU, RTL8188ETV, RTL8188FTV etc. don't implement those ioctls and therefor iw command is not working partially, or at all.
The OpenWrt uses /package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh to manipulate the WiFi and it's based on iw command.
The major issue in it is that it uses simplified way how to do so. First it removes all the interfaces and that creates them again with the new required setup. Generally it works, when the WiFi driver supports the needed commands, but when not, it fails.
I've solved it with the rewriting of iw commands with old-fasshioned ifconfig, iwconfig commands and it works now. I've modified only the AP functions which I need, but it will work for the other functions too.
I will suggest to include simple test if the WiFi driver supports the iw ioctls, or not and than use the appropriate commands in the mac80211.sh.
