Summary - wifi cannot be turned off  (netgear, wndr3700-v4)
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Low
Priority - Very Low
Reported Version - openwrt-21.02
Due in Version - Undecided
Due Date - Undecided
Details -   - **Device problem occurs on**: netgear, wndr3700-v4
  - **Versions of OpenWrt where the bug occurs**: 21.02-rc1 and snapshot
  - **Versions of OpenWrt where the bug does not occur **: 19.07 and 18.06
  - **Duplicates**: #3236

=====Steps to reproduce=====
 We should be able to turn wifi on/off via any of the following methods:
  -  The wifi button in luci
  -  The wifi button on the router
  -  uci set wireless.radio0.disabled=$x && uci commit && wifi up      (where x=0 to turn on wifi, x=1 to turn off wifi)

All three methods work to turn on wifi, but none of them work to turn off wifi.  (Wifi continues running, the wifi LED on the router remains illuminated, and a client can connect to wifi).  The problem occurs every time, on every boot.

The only way I have found to turn off wifi is, /etc/init.d/wpad restart
