Problem

OpenWrt wireless connections will not open the access point network if the client network is defined but the client network is unable to connect.
The below process indicates a solution to this problem.

fix

Flip all non connecting clients to disabled

service network restart

Make run on system after initialization

save somewere and add below line in /etc/rc.local

python /path/to/wififix
