RPi3's onboard WLAN interface requires crda package to work properly with channel 13 (usually I do not use the onboard WLAN)

Please install crda package (it is currently not installed per default) and after that run commands as follows:

Terminal

root@kmxbilr2 / # iwlist wlan0 scanning | grep Channel


Channel:1
Frequency:2.412 GHz (Channel 1)
Channel:1
Frequency:2.412 GHz (Channel 1)
Channel:1
Frequency:2.412 GHz (Channel 1)
Channel:11
Frequency:2.462 GHz (Channel 11)
Channel:11
Frequency:2.462 GHz (Channel 11)
Channel:4
Frequency:2.427 GHz (Channel 4)

root@kmxbilr2 / # iw reg set DE
root@kmxbilr2 / # iwlist wlan0 scanning | grep Channel


Channel:1
Frequency:2.412 GHz (Channel 1)
Channel:1
Frequency:2.412 GHz (Channel 1)
Channel:11
Frequency:2.462 GHz (Channel 11)
Channel:11
Frequency:2.462 GHz (Channel 11)
Channel:4
Frequency:2.427 GHz (Channel 4)
Channel:13
Frequency:2.472 GHz (Channel 13)

You see after setting REGDOMAIN to DE channel 13 is there

To make setting permanent please set variable REGDOMAIN to DE in file /etc/default/crda:

Terminal

root@kmxbilr2 ~ # cat /etc/default/crda
# Set REGDOMAIN to a ISO/IEC 3166-1 alpha2 country code so that iw(8) may set
# the initial regulatory domain setting for IEEE 802.11 devices which operate
# on this system.
#
# Governments assert the right to regulate usage of radio spectrum within
# their respective territories so make sure you select a ISO/IEC 3166-1 alpha2
# country code suitable for your location or you may infringe on local
# legislature. See `/usr/share/zoneinfo/zone.tab' for a table of timezone
# descriptions containing ISO/IEC 3166-1 alpha2 country codes.

REGDOMAIN=DE

Thanks a lot. Will try. I normally do that using country=de in the wpa_supplicant.conf.

Maybe changing this can be integrated with the wifi setup GUI.
