Wifi AP RTL8188CUS woes

[naesk]

Managed to get Raspberry Pi working as wifi access point using

dnsmasq, hostapd (hostapd-rtl871xdrv), iptables

(see previous post viewtopic.php?f=60&t=10428&p=52241&hilit=access+point#p52241 for my error)

All was working until I performed an update. Since then my Android phone reports Authentication problem.

I've also installed the 8192cu-dkms AUR as referenced on the main ArchLinux wiki but to no avail
https://wiki.archlinux.org/index.php/Wi ... #rtl8192cu

For completeness here are all the relevant info & configs
