Wlan1 stopped sending signal on WRT1900ACS

Hi, I have a WRT1900ACS running OpenWrt 18.06.1 r7258-5eb055306f

This has been installed and working fine for 3 months but yesterday I noticed that the 2.4G network was down, 5G is still ok.

Restarting the router made no difference.

In the OpenWrt GUI it shows wlan1 as:
Marvell 88W8864 802.11bgn
Channel: 6 (2.437 GHz) | Bitrate: ? Mbit/s

The wifi network shows 0% strength and none of my devices can see the 2.4G network.

below is part of /etc/config/wireless:

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 legacy_rates '1'
        option country 'GB'
        option htmode 'HT20'
        option channel 'auto'
        option log_level '2'

config wifi-iface 'default_radio1'
        option device 'radio1'
        option network 'lan'
        option mode 'ap'
        option macaddr '26:f5:a2:23:ec:a8'
        option key 'xxxxxxxxxxx'
        option encryption 'psk2+ccmp'
        option ssid '2.4Gnetwork'

Any help appreciated.


Logs, especially of the driver install, firmware install phase, as well as when the wireless is normally configured would be helpful.

Hi Jeff, thanks for the reply. In the OpenWrt GUI it displays the system logs and kernel logs, I can upload these if useful.
You mention logs of the driver install but it was a vanilla install a few months back and was working fine. Since the problem started I haven't re-installed the driver.

Happy to grab whatever would help.
