We were for years FRITZ! Box usual, ie DSL light off and LTE ago. So again a Speedport. LTE working with Speedport to update very good, just the whole network especially accommodate the NAS to the LAN port does not always work out. Therefore, back to Fritz, the first to set up super easy as with Fritz common network works perfectly. I will continue to report, after 3 days is a first impression. Meanwhile, I have the Fritz box returned. After just over a week always complete reboot of the box and sometimes for 10 minutes again. A reset to factory settings has brought nothing. This is especially troublesome during download and stream the movie. Now LTE runs again the Speedport II with light network constraints but stable.
