Every time I try to send a print over Prusa Connect, it takes forever, several minutes to transfer a very small file to the printer. I can see the transmission icon on the printer moving very very slowly, like 15 minutes for a 1.5 MB file, which makes no sense. It worked well in the past, but for a while is failing with this.
The printer is set ready (IDLE) successfully through Prusa Slicer Prusa Connect using Slicer ver: 2.9.0. When I send the print to the printer, it's a long while in "Downloading" state on the printer, sometimes it fails, sometimes it works well. I am noticing I get very long pings on the network panel, attaching all screenshots that might be relevant to check. Hope someone can help me with this one, because its getting quite annoying.

Printer shows: Bootload version 2.3.5
Firmware: 6.1.3+7898
Buddy Board: 9

I also tried changing the Prusa original Pen Drive for a Sandisk but got the same results.

Thanks a lot!
