Archer C7 v2 wifi leds don't work

Reported by: morfik Owned by: developers
Priority: normal Milestone:
Component: base system Version: Barrier Breaker 14.07
Keywords: wifi, led Cc:


I have Archer C7 v2 router:

 | Machine: TP-LINK Archer C7                                   |
 | Uptime: 0d, 00:01:06                                         |
 | Load: 0.43 0.17 0.06                                         |
 | Flash: total: 12.3MB, free: 10.9MB, used: 11%                |
 | Memory: total: 123.4MB, free: 101.7MB, used: 17%             |
 | WAN:, proto: dhcp                              |
 | LAN:                                             |
 | WLAN: mode: ap, ssid: Valar_Morghulis, channel: 36           |
 | WLAN: mode: ap, ssid: Ever_Vigilant, channel: 8              |

Wifi 2.4GHz and 5GHz work without a problem, but I can't say the same about their leds.

First of all, the configuration in /etc/config/system is wrong. I mannaged to fix 5GHz wifi led by adding to the config file the following lines:

config led 'led_wlan5g'
        option name 'WLAN5G'
        option sysfs 'tp-link:blue:wlan5g'
        option trigger 'phy1tpt'

There's a similar configuration for the 2.4GHz wifi already specified in the config file:

config led 'led_wlan2g'
        option name 'WLAN2G'
        option sysfs 'tp-link:blue:wlan2g'
        option trigger 'phy0tpt'


# cat /sys/class/leds/tp-link\:blue\:wlan2g/trigger
[none] switch0 timer default-on netdev heartbeat usbdev phy0rx phy0tx phy0assoc phy0radio phy1rx phy1tx phy1assoc phy1radio phy1tpt

There's no phy0tpt trigger for wifi 2.4GHZ. I checked if the other phy0 options work and set phy0rx instead. The led blinks, so it looks like the phy0tpt is missing.

In my system the 2.4GHz interface is on phy1 not phy0.

It seems the leds are inverted.

After today's upgrade (Barrier Breaker (r43962), everything works just fine.

As for the inverted leds -- no, I just prefer them in that way, so that's why I switched them.

comment:7 Changed 3 years ago by anonymous

fine then, however they are inverted also on my router and I didn't change the standard configuration.

I still experience this problem with BB (r46516).
The wlan5g part is missing from /etc/config/system.
