Well, I found necessary parts in my parts pile and did the antennae mod last night and it worked!
-52db, and most importantly the file is uploading and not failing. speed is also as high as I have ever seen with up to 1mb/s but average around 500-700ish.
Still strange why I had to do this because it worked fine before. the wifi access point is literally less than 25ft away with almost direct line of sight, so i don't really get it.
Well, one problem solved (for now). hopefully stays working.
@Phaedrux I bough this duet in 2017 .... so I guess any warranty is already gone.
The nearby PC is showing -29DB.
I guess -67 isn't that bad.. but then why wouldn't it be able to upload any files?
Duet is in a 3D printed case at the bottom of the printer (open frame design) There is no metal really near it at all.
Also its showing the AP mode hotspot as a wireless B device.... is that even right?
@infiniteloop
Wow, that is awesome. I love those mac case mods.
Ok, so AP mode has the following result
So yeah... I guess it's just a crap antennae?
@Phaedrux
Good idea, i will try AP mode and see what happens before I try anything with the wifi card
@infiniteloop
Ok, I have to see a photo of the G4 Duet now lol. Also which trace did you cut? i could not tell from your photo.
@infiniteloop Well, i could try that first. Did it work out well for you?
Which trace did you cut, can't tell from the photo
Also yes I have tried another SD card.... no change.
@Phaedrux Mine does not have the external antennae, it's the older one with the little PCB antennae.
I saw this thread
https://forum.duet3d.com/topic/2825/converting-the-duet-wifi-to-use-an-external-antenna
Maybe i should just do this?
@Phaedrux Well the problems continue, it's basically still doing the same upload / slow / fail behavior. At this point it seems like a hardware issue. Are the wifi chips known to fail? could my antennae be damaged / bad? I have no wires near the antennae, it's exposed, very close to the AP, etc. It should be fine.
@Phaedrux
I just tested again, uploaded a file and I am getting ~350 KiB/s, and it did not fail. I tried 4-5 times. So this is better, but previously uploads completed in under 10 seconds at most.
So this is usable again at least, im still stumped as to what changed because i've been using this same board, same wifi system, etc for years so nothing really has changed in my setup.
OK, dowgraded to 1.27, static IP is working. -55db signal strength, didnt try to upload a file yet. Should i just not upgrade the wifi server anymore?
Will try after the current print finishes. I think 1.27 is what I previously had, then i updated to 2.1beta3 to try and solve this issue. Should i just revert back and leave it? I will check the band steering option also. M552 P192.168.0.215 ; set static IP was working on the old 1.27 version.
edit, ok band steering appears to be a setting for the AP, not per client, but I checked all 4 APs I have and it was already off.
So after updating my duet, wifi firmware, etc I finally realized the issue was the printer was trying to connect to the Unifi AP 2 floors down, instead of the one 20 feet away from it. I updated and restarted my wifi mesh system and now the signal strength is -50db, so its better. But upload is still a little slow, but it didn't fail at least. Something strange is still going on because I have 3 other printers in this room and they don't have connection issues. (also this duet previously was working for years just fine)
But now I created a new issue for myself, since updating the wifi server to 2.1 beta3 my static IP does not work at all.
Previously, my config.g had this line in it:
;M552 P192.168.0.215 ; set static IP
Now it does nothing, I also tried this in config.g
;M587 S" " P" ." I192.168.0.215 ; set static IP
And no luck. What is the proper way to set static on the new wifi server?

@dc42 It's only on bootup. I tried putting that line at the very beginning of the config, but no change. I guess config is not being loaded fast enough before it pops the error?
That's a possibility, I'll have to check if channel has changed. Nothing else has changed with the wifi environment. I am using Ubiquiti AP and I don't have issues with any other devices, oh another thing to mention is my Formbot troodon is 2 feet away from the printer having the wifi issues and the Troodon works perfectly fine.
I changed the AJAX number of retries to 6, from 2 and it fails less now , but still very very slow.
It looks like I already had that line in the config, so i guess i am just stuck with it. That's fine, will just ignore it.
Does anyone know how I can fix this? The printer works but on every bootup I still get this after updating to 3.4.4

Here are my diagnostic results

-64 is a bit low right? but the question is nothing has changed, printer has not moved... why would it be worse all of a sudden?
I recently have been having an issue with my Duet 2 wifi, where gcode files are taking a long time to upload, and half the time they fail.
If using DuetRRF plugin in cura, files upload extremely slow and then error out with the message "networkerror.unkownnetworkerror unable to write"
If using DWC, The file starts to upload at extremely low speed, and sometimes the progress actually drops down / goes backwards and then eventually just fails.
If i try uploading 5-10 times eventually it works, but still slow.
Any suggestions? not sure what is happening. I thought maybe the SD was failing so I copied the files to a new 32GB sandisk but same results.
@phaedrux Both on 3.4.1rc1
The one with the button has paneldue 3.4 , and the troodon has 1.25. the UI on both looks identical though.
I have to printers, one with a duet2 and paneldue, another is a TroodonCoreXY which also uses reprapfw and paneldue. On my duet2/paneldue printer I have a "print again" button under my control tab, but the Troodon dosen't have that, I can't find anywhere in the settings to enable it either. Is there some way to turn it on?
@phaedrux said in Formbot Troodon RRF 3.1.1 Update:
M575 P1 B57600 S1
Thanks, this worked. I think it's all working now. I noticed the fans are running louder than before so that's next to figure out.
