Hello,
IPv6 support on mobile WAN is under development, currently we have a TEST firmware for it but there is an issue that if mobile signal is not stable and it disconnect from operator router will not try to establish mobile connection again. But this can be solved by using Ping reboot feature which can be found in Services -> Auto Reboot -> Ping Reboot simple enable it and save setting, everything else leave as it is.
Other solution is simple to reboot device, this can be done by:
- sending SMS command: reboot (SMS syntex: <routers admin password reboot>) Example: Admin147 reboot
- from WebUI in System -> Reboot
- from SSH by using command: reboot
Attaching TEST FW: https://community.teltonika-networks.com/?qa=blob&qa_blobid=3291963135140819944
Note.: this is a latest TEST FW for IPv6 WAN support and you might incounter some issues. We currently working on new FW with improved IPv6 feature (no lead time for it).
