WiFi Issues - "Network Error" on uploading almost every file

TheBasedDoge

Thanks for the link. I might order one of those although I'm still not sure that is my issue since my duet has been working fine for years, in the same spot, up to this point.

I have still consistently been able to upload files via the old duet web interface EVERY time, while files failing consistently on the new duet web interface. I think something is wrong with the new interface.

Will also check the settings / stats on my Unify to confirm.

That definitely sounds like a Dwc2 issue.

Can you try clearing out the www folder and recopying the files fresh from the latest release?

I think it would be well worthwhile to do a quick wifi scan (free software is available) to check out the spectrum around your setup. It would be quite consistent with the symptoms reported that a neighbour has set up a new wifi device on either the same channel or on either side of it. That would account for it sometimes working and many times not despite an acceptable (?) signal level.
I have seen some pretty odd things happening with wifi - it definitely is not a situation like a cable where you just plug it in and it works.

@jens55 the unifi controller can do a scan too.

okay I was ready to swap the wifi module but before that I tried to just "extend" the antenna... believe it or not it worked. I hadn't a single disconnect since

Basically cut the onboard antenna and soldered a new one. The antenna must be of a very specific length (check 2.4 antenna length) but apart from that it's a 5 minutes hack.

Now, I don't suggest to anyone doing that... but it worked for me.

The built in antenna is very small, also for best signal strength it should be mounted vertically to match the antenna direction in routers, not horizontally as you have it.

that is interesting, thanks for the heads-up! The antenna hack fortunately worked very well but good to know for the next duet Even though the next duet will be surely with external antenna module.

Just had this happen to me as well. I think it had to do with the filename being uploaded.

The file had a " double quote in it. Every time I tried to upload it, I would get a network error message. Removing the quote mark and it uploaded fine.

So if anyone gets this error in the future, check your filename for special characters.

I had this situation because of the long file name.

From https://docs.duet3d.com/en/User_manual/Reference/Gcodes#filenames-and-paths

Full paths, including all directories and subdirectories are limited to 120 characters. e.g.:
0:/gcodes/0123456789/012.gcode
counts as 30 characters
