I'm interested in Open Source and in OpenWRT as I'm traveling and working from a camper van. Modemmanager is a great peace of software, and the implementation on OpenWRT is a super-cool thing for the OpenWRT community.</div><div dir="ltr"><br></div><div dir="ltr">Environment:</div><div dir="ltr"><span style="caret-color: rgb(64, 64, 64); color: rgb(64, 64, 64); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; text-align: left; background-color: rgb(255, 255, 255); display: inline !important;">TP-Link TL-WR902AC v3 / <span style="caret-color: rgb(64, 64, 64); background-color: rgb(255, 255, 255); display: inline !important;">OpenWrt 19.07.5 r11257-5090152ae3 / LuCI openwrt-19.07 branch git-21.222.69112-b41f377 / Telkom Speedstick V / Modemmanager Luci-proto manually integrated</span></span></div><div dir="ltr"><span style="caret-color: rgb(64, 64, 64); color: rgb(64, 64, 64); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; text-align: left; background-color: rgb(255, 255, 255); display: inline !important;"><span style="caret-color: rgb(64, 64, 64); background-color: rgb(255, 255, 255); display: inline !important;">Raspberry Pi B+ / OpenWrt 21.2.3 / Vodafone K6150</span></span></div><div dir="ltr"><br></div><div dir="ltr">Now my questions:</div><div dir="ltr"><ol><li><span>After connecting the bearer token has statement IPv4-Config / IPv6-Config which includes the config-method (DHCP, static, ppp). I wonder who is setting this. Is this coming from the device (4G stick) or is this setting provided by the network-provider the device has registered into?<br></span></li><li>If you roam with the 4G stick you sometimes get IPv4 only, but in the home-net you will get IPv4/IPv6 dualstack. Is it fair to say the network (roaming access-provider) assigns the IP stack, regardless if your home apn does support dualstack or not?</li><li>Is there in ModemManager a capability to pick a roaming network over the other, so I could pick always best one? Is the signalquality a good indication of good performing network?<span style="font-size: inherit;"> </span></li></ol></div><div dir="ltr">Thanks, Thomas</div><div dir="ltr"><br></div><div dir="ltr">Please advice, if I should ask better questions and how I should do better</div><div dir="ltr"><br></div> <div id="ms-outlook-mobile-signature"><div><br></div> Holen Sie sich <a href="https://aka.ms/o0ukef" style="">Outlook für iOS</a></div> </div> </div></body></html>
