Because of some weird behavior on the part of my Internet provider at the moment, I am unable to comment at this time on the bandwidth (possibly restrictions on a cheap tariff). - Several people have written that the router with the 2022 firmware has signal limits, and that this may be solved by placing the Chinese one in its place; nevertheless, I have not had any problems up to this point.
