Hardware: Archer C7 V2
Software: 19.07 but also hapoened eith 18.06

There seems to be irregular behaviour of the WiFi physical on/off switch for the device. Sometimes the key appears to make no difference. And sometimes it appears to be in the opposite position, and sometimes it appears to work properly.

And the last instance: after a blackout, the Wireless didn't work. I restarted the device but still it didn't work. WiFi switch was in the on position, I urned it off but that made no difference, then turned out back on and it worked!

I can't get sense of what's happening, but there is certainly an issue there.

From what I remember, these switches were never really implemented correctly, and are effectively working as a flawed button.

But the discussion about that was about one year ago, so I do not remember the details. There should be something in the openwrt-devel archives about that.

I didn't reported this issue because I didn't take too much into account, but the issue is just archer c7 v1 and v2 has wifi interrupter, and v4 and v5 has wifi switch button.

The erratic behavior over the v2 is just wrong definition. I could test also v4, but the issue there I think was that the switch button was used for wps/wifi toggle depending how much it was pressed.

@howl Where do you see a wrong definition? Both ath79 and ar71xx have EV_SW for WiFi ...

Indeed, I will have to recheck the button behavior because I remembered like that was the problem but I could be confusing another model. Sorry.

ath79: increase the rfkill debounce interval for TP-Link Archer C7 v2
220ab83 
Due to circuit issue or silicon defect, sometimes the WiFi switch button
of the Archer C7 v2 can be accidentally triggered multiple times in one
second. This will cause WiFi to be unexpectedly shut down and trigger
'irq 23: nobody cared'[1] warning. Increasing the key debounce interval
to 1000 ms can fix this issue. This patch also add the missing rfkill
key label.

[1] Warning Log:
```
