Raspberry Pi 3 built-in WiFi SSH NTP Problem

Maverick82 · June 6, 2016 at 9:01 PM

I have a problem with NTP and built-in WiFi on Raspberry Pi3.

Under Rasbian the following command solve the problem with the builtin Wifi:
/sbin/iptables -t mangle -I POSTROUTING 1 -o wlan0 -p udp --dport 123 -j TOS --set-tos 0x00

If placed in rc.local it is automatically executed at boot.

But under libreelec, this command doesn't work, the file rc.local doesn't exists and I don't know how to make the equivalent adjustment under libreelec.

Could anybody help me?

1) we don't support TOS as we don't have CONFIG_IP_NF_TARGET_TOS set.

Code

LibreELEC:~ # cat /proc/net/ip_tables_targets
MASQUERAD
EERROR

2) you can use /storage/.config/autostart.sh for commands that should run on boot.

Maverick82: presumably you're referring to this post? I've tested NTP with RPi3 built-in WiFi and didn't have a problem, which might suggest its a problem with certain access points rather than a widespread problem (otherwise there'd be a lot more noise around this issue).

Unfortunately in that thread there seems to be a number of people saying there's a problem, yet no issue opened on github which is the correct way to progress towards a fix.
