New FW: wireless have add a new section
I want to upgrade to new FW and backup wireless config, but after upgraded, then old wireelss config file have covered new wireless config file that with a new section. So I must do factory reset 
There are any better way to backup wireless config and save new section after upgrade?

From LuCI: System -> Backup/Flash Firmware -> Backup old configuration
This will give you a TAR archive containing all your configuration files. Then upgrade to a newer FW and clear the existing config. Now manually paste over those bits from the old config that you need.
Usually the config files are compatible between versions, but sometimes new things have been added and old things refactored so that the config files simply aren't compatible.
The discussion might have continued from here.
