I can now answer the question myself: With Swisscom, I use LTE band 3 (1600MHz). Sunrise/yallo uses LTE band 20 (800MHz). The latter allows coverage of a larger area (e.g. in the countryside), but usually at lower speeds. In my case, the Sunrise band 20 is significantly stronger than the Sunrise band 3, which is why the router selects the slower band 20. The official firmware does not allow manual
selection. However, there is a beta firmware in which you can select the band (Google search helps). Installed and selected band 3 manually. And look: at least 9Mbit/s up and down. I can live with that as a backup internet connection.Thanks for the tip!
