Openwrt wifi not working

Fix for Linksys EA3500 with OpenWRT 2.4GHz Wifi not working

In /etc/config/wireless , under the config wifi-device ‘radio0′ section, change the option hw_mode ’11a’ line to option hw_mode ’11g’ and restart. See the bottom of this post for an example.

Here is my thread on the OpenWRT forums.

I recently installed OpenWRT firmware on my Linksys EA3500 router so I could send WOL (Wake-on-LAN) packets to my PC to turn it on from outside of my local network. Everything worked great except for the 2.4GHz WiFi (radio0).

I looked through the system logs and found this:

# logread | grep radio0 . radio0 (2030): Hardware does not support configured mode radio0 (2030): wlan0: IEEE 802.11 Hardware does not support configured mode (2) (hw_mode in hostapd.conf) radio0 (2030): Could not select hw_mode and channel. (-2) . 

The referenced hostapd.conf is actually /var/run/hostapd-phy0.conf which is automatically generated from /etc/config/wireless . If we look in /etc/config/wireless we see this configuration for radio0:

# cat /etc/config/wireless config wifi-device 'radio0' option type 'mac80211' option path 'mbus/mbus:pcie-controller/pci0000:00/0000:00:01.0/0000:01:00.0' option hwmode '11a' option channel 'auto' . 

«IEEE 802.11 Hardware does not support configured mode (2) (hw_mode»

This error tells us that the WiFi device’s wireless protocol ( hw_mode / hwmode ) has been improperly configured. As you can see from the configuration above, by default radio0 is incorrectly configured as a 5GHz radio with the 802.11a/n protocol ( 11a ). To fix this we need to change the value to 11g to correctly configure the radio to use the 802.11b/g/n 2.4GHz protocol.

Specifically, we need to change the option hw_mode ’11a’ line to option hw_mode ’11g’ in /etc/config/wireless like so:

config wifi-device 'radio0' option type 'mac80211' option path 'mbus/mbus:pcie-controller/pci0000:00/0000:00:01.0/0000:01:00.0' option hwmode '11g' option channel 'auto' 

Restart the router to cause /var/run/hostapd-phy0.conf to be regenerated from your new /etc/config/wireless .

I am not seeing any errors in «dmesg» or «logread», but the wifi is not working on OpenWRT.
@kraj Could you please let me know, what are all the configurations required to bring up the wifi on OpenWRT.

The text was updated successfully, but these errors were encountered:

if you use latest master meta-raspberrypi layer it uses right firmware blobs to bringup on-board wifi
I have not tried to bring up wifi on pi3 myself with openwrt layer but it works fine with OE in general

@cshoredaniel ,
I am replying on behalf of Satish Naidu, we work together.
We are including netifd and using it.
when we try apply the wifi config and try bringing up wlan0 is shown up in ifconfig -a but wlan0 link is not ready. Please suggest how to get it work on yocto with openwrt layer.
Below is our configuration to bring up wifi on opewrt platform.
In file /etc/config/wireless:
config wifi-iface
option ssid ‘linksys’ # the wifi name its connecting too
option device ‘radio0’ # the radio we are using to connect
option mode ‘sta’ # client mode
option key ‘password’ # wifi password
option encryption ‘psk2+ccmp’ # encryption level
option network ‘wwan’ # interface name (used for dhcp and firewall zone etc)
option bssid ‘xx:xx:xx:xx:xx:xx’
In file /etc/config/network
config interface ‘wwan’
option proto ‘dhcp’
In file /etc/config/firewall
config zone
option name ‘wan’
option input ‘REJECT’
option output ‘ACCEPT’
option forward ‘REJECT’
option masq ‘1’
option mtu_fix ‘1’
option network ‘wan wwan’

Ah, I though you were doing AP mode. Do you have wpa_supplicant? (I’m not sure if that’s enough or if a recipe doing OpenWRT-like multi-call wapd is necessary for client mode). Does the client attempt to make a connection but fail (i.e. when you watch wireless traffic)? Do you have busybox’s udhcpcd included? (netifd doesn’t grok dhcp-client from ISC). Regards, Daniel
