Reassigning LED to tun0 on BTHH5 works for 30sec then stops

Installing and Using OpenWrt
1

Assinging the broadband LED to the tun0 interface to indicate vpn activity works for 30sec to 1 min then the broadband indicator goes off. The openvpn connection is fine and if I make a change in Luci to the LED the indictor again works for ~1min then stops. This on a plusnet with 19.07.7
A minor irritation but does any one have suggestions about a fix?

Post your /etc/config/system file, someone may have some insight based on that.

fwiw, your issue may be caused by having both 'tx' and 'rx' enabled. Try unchecking one of them. You may have to remove 'link' too.

Personally, I only enable 'link on'.

I think I have tried all combinations. Certainly the same behaviour with just link on

Removing dsl_control from startup fixes the problem
