Do you do this at a later stage? 3) From the NetworkSetup_AP: <snip> ifconfig_wlan0="channel 6 ssid MakerSpaceLeiden_gasten up" ifconfig_wlan1="channel 6 ssid MakerSpaceLeiden_deelnemers up" ifconfig_wlan2="channel 48 ssid MakerSpaceLeiden_5G_gasten up" ifconfig_wlan3="channel 48 ssid MakerSpaceLeiden_5G_deelnemers up" ifconfig_wlan4="channel 6 ssid MakerSpaceLeiden_IoT up" </snip> The channels will be the same in all access points. Will this lead to instabilities when the access points are in close proximity? Thank you for your explanations. -- Met vriendelijke groeten, With kind regards, Mit freundlichen Gruessen, Will ************************************* W.K. Offermans Powered by ....
