Have a friend who runs his laptop with a surfstick. He has to put this on a long cable to another place. Nevertheless, sometimes the reception is bad. Even with the cellphone you have in his apartment very bad reception. Is there an amplifier for this?
Yes, but they are 1. Expensive and 2. In D forbidden.
I recommend an LTE stick or better router, with antenna slots.
They alone can increase the reception quality.
Alternatively, you can attach and connect outdoor antennas, which would of course be the best.
By radio outdoor antenna (for example, on the house) directly to the strongest radio mast.
