Thank you for your answers. I am aware that the upload rate depends on the antenna operator, location and time of day.

However, my question related to the theoretical maximum upload rate, i.e. what is the maximum that the device can deliver "under laboratory conditions"?
Digitec does not give any information here, other suppliers state a maximum of 280 Mbps, while others write that the router can upload up to 2.5 Gbps.

It depends on your ISP...

In the beginning, the upload speed was up to 500 and the download speed was 150 as a normal average. The maximum speed in the morning hours was up to 1000 megabytes per second and the download speed was 170.
