      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.

        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?

          Well 2.1 is a beta release for testing, so your findings are useful. You can continue to use 1.27 for now and we'll have to investigate the issue.

          I'm curious to know if your upload performance is better or the same.

            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.

              You could try stepping back to 1.26 and 1.25 to see if it's something in those updates that changed.

                @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.

                  Is this a Duet wifi with external antenna?

                    @Phaedrux Mine does not have the external antennae, it's the older one with the little PCB antennae.

                    I saw this thread

                    Maybe i should just do this?

                      That's the proper way to do it. I've done it "improperly": I cut the 'inner' one of the two traces and soldered the external antenna as in the photo:

                      On the matter of slow uploads: have you ever tried another SD card?

                        @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.

                          One thing I would suggest trying to help isolate the problem is to setup the Duet in Access Point mode. This takes the entire wireless router out of the equation. The duet creates it's own wifi network and your connect your device to that network. Then test at least 2 different computers to see if it's the duet hardware or your computer wifi device that is having the issue. If you get better performance like this, that would indicate something off with the wireless router settings or interference. If the problem persists with both devices, the Duet hardware is most likely having an issue. If only 1 device has an issue, the problem likely lies there.

                            Yep. I built my Duet into a modded Apple G4 casing - internally, that has a solid metal cage, but I re-used Apple's WiFi antennas: works flawlessly since 2019 😊

                            Also yes I have tried another SD card.... no change.

                            Sorry to hear that.

                              Good idea, i will try AP mode and see what happens before I try anything with the wifi card

                                Promised. Will try to take some shots… if that works in the darkness over here.

                                Back in 2019, I found this on the web: ESP mit externer WLAN Antenne. You don't need a translator to understand, just look at this image from that post:

                                    Wow, that is awesome. I love those mac case mods.

                                    @Phaedrux

                                    Ok, so AP mode has the following result

                                    • With a computer 1ft away from the printer I was able to upload a file no problem, it maxed out 400kib/s. I only tried one time but it worked the first time.
                                    • With my desktop PC that I normally use in the next room over, it took several minutes to even bring up DWC. i started a transfer and it's going at like 30 kib/s at most, and finally failed. WifiInfoView shows me signal strength is -67db.

                                    So yeah... I guess it's just a crap antennae?

                                      I mean, -67db isn't that bad really. Not amazing, but not great.

                                      What did the computer right next to it get for signal strength?

                                      The fact it worked properly on the near computer at least lets us know the hardware is working and points to where the issue is.

                                      If you wanted to try the antenna mod, that's up to you, but would definitely void any warranty you may have remaining. (6 months from purchase)

                                      How is the Duet mounted? Is there any metal near the antenna?

                                        @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?

                                          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.
