Can't upload "large" files

It may be worth exploring what the ubiquity has for options particularly with 2.4ghz clients.
-
In what regard? I'm running a separate SSID for 2.4Ghz and 5Ghz with the printer on a static ip outside the DHCP range, and all band steering is disabled since i have separate SSID's.
Just checked what connection i have to the printer from the AP side and it say -61dBm there, which sould be more than enough as far as i can understand.

Try uploading with FTP and see if it's any different.

Forgot to mention that, FTP's totally useless. When i connect with winscp, and go to say macros, and then try to go back root it crashes and i get timed out. -

The ncftpput command seems to work reliably for just uploading a single file.

Well, except for the first attempt after the Duet resets.
Not a permanent solution of course but it may indicate where the issue lies.

I think the issue is the low signal strength (-70dBm), which combines with the small antenna size on the WiFi module to give this type of problem. The simplest solution is probably to put a WiFi repeater in the same room as the printer.

Okey, then i'll try with another AP in the second floor haha.
What speeds is normal on the transfere btw?

With a good signal strength in an uncongested WiFi environment, 700 to 900 kbytes/sec is typical.

Where I have my printer connected to is similar, and I'm not getting any issues uploading, so I would say that -70dBm is good enough.I have -71dBm connected through a Ubiquiti AP-AC-LR
Unifi reports a -65 dBm signal and a TX rate of 65 Mbps
I have speeds of around 200-250 kb/s as well, which I had before too located closer to an AP.FYI my phone connected to the same AP has a self reported signal of -65dBM and a TX rate of 130 Mbps, while Unifi reports it has a -82 dBm signal and TX rate of 234 Mbps. My phone is about 4 meters further away from the AP.
-
The reported TX rate is unrelated to actual attainable throughput and is "just" dependent on the chosen wifi variant (i.e., 5GHz will almost always show you a higher tx rate even though that is only attainable in oractice at very short distances between AP and client).
My duet WiFi is located at the outskirts of home WiFi range and if a large mass of water intervenes between the WiFi AP and the printer (i.e., if I sit between the both), the signal is sometimes dispersed well enough to make uploads impossible.
And, as I learned from working on large WiFi installations, the best way to fix WiFi issues is to switch to Ethernet (-: (only applicable where practical).

The problem with wifi is the lack of wires. Air is an awful conductor.
