No WiFi on Archer C7 v1 with 19.07.0

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi, today I also upgraded my Archer C7 v1.
I did the migration from ar71xx to ath79 by sysupgrade -n -F https://downloads.openwrt.org/releases/19.07.0/targets/ath79/generic/openwrt-19.07.0-ath79-generic-tplink_archer-c7-v1-squashfs-sysupgrade.bin

After upgrade I migrated my previous settings from /etc/config (network/firewall/wifi) step by step.
The only problem I have, it seams that WIFI is not working.

iw phy list the wifi device - but iw dev gives no output.

my wireless config is this:


config wifi-device 'radio0'
        option type 'mac80211'
        option channel '13'
        option hwmode '11g'
        option path 'platform/ahb/ahb:apb/18100000.wmac'
        option htmode 'HT40'
        option ht_coex '1'
        option country 'DE'
        option country_ie '1'
        option disabled '0'
        option noscan '1'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option ifname 'wlan2g'
        option mode 'ap'
        option ssid 'XXXX'
        option encryption 'psk2+ccmp'
        option key 'XXXX'
        option wpa_group_rekey '300'
        option wps_pushbutton '1'
        option disabled '0'

config wifi-iface 'guest_radio0'
        option device 'radio0'
        option network 'guest'
        option ifname 'wlanGast2g'
        option mode 'ap'
        option ssid 'XXXX Gast'
        option encryption 'psk2+ccmp'
        option key 'XXXX'
        option wpa_group_rekey '300'
        option wps_pushbutton '1'
        option disabled '0'

Any Idea what is going wrong?

argr... ok totally my fault!

I have not installed the hostapd package - the settings was not working with wpad package.

Now it seams to work :slight_smile:

if you want to build you can get 5ghz working too :wink: https://github.com/openwrt/openwrt/pull/2674

what you mean by:

it does not fix the issue of occasional PCI crash during bootup

In the past, this device had boot issues, which I had to solve by remove the kernel module:

How does the device boot with your patch?

sometimes it will crash on boot, reboot by itself until it boots properly. after that AC wifi works
