Hi!
I have a strange problem here. My 2.4Ghz wifi radio on the Linksys WRT1900acs does not work. I can configure and enable it without problems, but the ssid on multiple client devices is not shown. Therefore i can't connect to the network using this radio.
I just noted the problem recently after running my configuration for some years. I have an additional router/ap with 2.4Ghz wifi which acted unbeknownst to me as fallback (same ssids are used). I can't say for sure, if it ever worked.
Before posting here i tried updating openwrt. Currently i run openwrt-21.02 branch (git-21.231.26241-422c175) / OpenWrt 21.02.0 r16279-5cc0535800
. My wrt1900acs should act as dump ap.
Here is my configuration:
/etc/config/network
:
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'xxx::/48'
config device
option name 'br-lan'
option type 'bridge'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'
config interface 'lan'
option device 'br-lan'
option proto 'dhcp'
config device
option name 'wan'
option macaddr 'xxx'
config interface 'wan'
option device 'wan'
option proto 'dhcp'
config interface 'wan6'
option device 'wan'
option proto 'dhcpv6'
/etc/config/wireless
:
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11a'
option path 'soc/soc:pcie/pci0000:00/0000:00:01.0/0000:01:00.0'
option htmode 'VHT80'
option country 'FR'
option cell_density '0'
option channel '56'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option macaddr 'xx'
option ssid 'fast'
option encryption 'psk2'
option key 'xxx'
config wifi-device 'radio1'
option type 'mac80211'
option hwmode '11g'
option path 'soc/soc:pcie/pci0000:00/0000:00:02.0/0000:02:00.0'
option cell_density '0'
option channel 'auto'
option country 'DE'
option legacy_rates '1'
config wifi-iface 'default_radio1'
option device 'radio1'
option network 'lan'
option mode 'ap'
option macaddr 'xxx'
option ssid 'slow'
option encryption 'psk2'
option key 'xxxx'
The 5Ghz wifi works as intended. But 2.4ghz with ssid slow
seems to be not broadcasting at all. The ip of the bridge device is configured via dhcp from the main router/ap.
Status of the radio1 (2.4ghz) looks fine:
"radio1": {
"up": true,
"pending": false,
"autostart": true,
"disabled": false,
"retry_setup_failed": false,
"config": {
"hwmode": "11g",
"path": "soc/soc:pcie/pci0000:00/0000:00:02.0/0000:02:00.0",
"cell_density": 0,
"channel": "auto",
"country": "DE",
"legacy_rates": true
I am playing around with the configuration for hours and can't get it to work. I am running out of ideas here. Is something something obviously from in my configuration?
Help would be really much appreciated.
