I just released a refresher for OpenWrt WebUI alpha package. It fixes a bug, which was reported by several people.
Some users had problems with Net configurator applet, if
wl0_country_code was unset in NVRAM. While it is extremely easy to set, I suggest reinstalling webui. Please read the original post on how to do it.
Thank you guys for your great feedback! Working together we will make webui even better.
