Problem loading files to SD through acess point

Hi,
i’m having a issue with the uploads of the files to the printer A1,
wireless connection with the printer is very poor,
i use a router huawei b311 221, as a acess point.
bambu studio finds the printer and i can do everything,
but when i try to upload…
i have a error:
Captura de ecrã 2025-03-14 095336
is there any thing that i can do?

best regards.
