I haven't tried the force_link, though, I'll give that a try. I know it won't work in "Registered", but maybe it'll keep it from dropping less often? I'll try it out and report back.</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1545316123929_6088"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1545316123929_6154" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;" id="yui_3_16_0_ym19_1_1545316123929_6153"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1545316123929_6152"> <div dir="ltr" id="yui_3_16_0_ym19_1_1545316123929_6151"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1545316123929_6155"> <hr size="1" id="yui_3_16_0_ym19_1_1545316123929_6194"> <b><span style="font-weight:bold;">From:</span></b> Nick <mips171@icloud.com><br> <b><span style="font-weight: bold;">To:</span></b> Aleksander Morgado <aleksander@aleksander.es> <br><b><span style="font-weight: bold;">Cc:</span></b> Peter Krause <peter@uringme.com>; ModemManager <modemmanager-devel@lists.freedesktop.org>; Russ Westrem <lspwaterproofing@gmail.com><br> <b><span style="font-weight: bold;">Sent:</span></b> Wednesday, December 19, 2018 5:49 PM<br> <b id="yui_3_16_0_ym19_1_1545316123929_6205"><span style="font-weight: bold;" id="yui_3_16_0_ym19_1_1545316123929_6204">Subject:</span></b> Re: OpenWRT Sierra EM7455 drops connection while driving<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1545316123929_6177"><br><div dir="ltr" id="yui_3_16_0_ym19_1_1545316123929_6179"><div class="yqt3687591938" id="yqtfd45741">Hey,</div><br clear="none"><br clear="none">By default (at least for me) ModemManager uses proto static to set up the network interface. Linksensing is disabled by default for static protocols as far as netifd is concerned, but you an override this by setting option force_link ‘0’ on the modemmanager interface. When this is set the connection will be brought back to life when reconnection of the modem occurs.<br clear="none"><br clear="none">I have not tested this while driving, but it does work in a static location whereas before it would not recover after such an event, (e.g. disconnecting the antennas). Test it out and let us know.<br clear="none"><br clear="none"><br clear="none">Best,<br clear="none">Nicholas</div><br><br></div> </div> </div> </div></div></body></html>
