# WLAN configuration¶

Gluon allows to configure 2.4GHz and 5GHz radios independently. The configuration may include any or all of the three networks “client” (AP mode), “mesh” (802.11s mode) and “ibss” (adhoc mode), which can be used simultaneously (using “mesh” and “ibss” at same time should be avoided though as weaker hardware usually can’t handle the additional load). See Site configuration for details on the configuration.

During upgrades the wifi channel of the 2.4GHz and 5GHz radio will be restored to the channel configured in the site.conf. If you need to preserve a user defined wifi channel during upgrades you can configure this via the uci section gluon-core.wireless:
uci set gluon-core.@wireless[0].preserve_channels='1'
