This way regardless of network interface it will maintain the value.</div><div id="yui_3_16_0_ym19_1_1510676841762_236339"><br></div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr">I have also seen cases where the DNS IP does not get updated correctly after reboot on Pi3 systems when using DHCP. From the best I can tell, it appears the correct values are written to /var/run/resolvconf/interfaces/wlan0 but resolvconfig tries to read it immediately after but it was not written yet (slow flash card). My recommendation to work around it to add $(which resolvconf) -u to /etc/rc.local. This give enough time between the write to the flash card. The result is /etc/resolv.conf has the correct values.</div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr">Your thoughts?</div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr">Darren</div><div id="yui_3_16_0_ym19_1_1510676841762_236339" dir="ltr">KJ6KFB</div></div></body></html>
