Duet Wifi-Establishing Wifi connection requires multiple resets
-
I recently purchased a Duet Wifi. I have experience a bunch of issues which I'll report on separately.
The biggest issue I have right now is getting on my wifi network. This has been the most annoying.
The only way I can establish connection is to either send M552 S1 a minimum three times (pausing between commands) through YAT terminal session or by pressing the Reset button on the DUET also a minimum of 3 times (sometimes 4)(pausing between presses). If I initiate a reboot from the web interface (emergency stop or config file edit) I need to perform the same routine.
The board came with 1.21, I updated the firmware to 2.02RC1 hoping to solve the issue, it didn't.

@bricor did you also update the wifi firmware and the DWC?
Have you seen this?

Most, if not all from that article do not seem to apply to my situation.
I have been through the steps listed that could possibly apply with no success.Signal is strong, Duet is wired in a plastic (printed, PETG) box sitting on the work bench (wood) 200-300 mm away from the printer and 500+mm away from everything else. there are no wires running near that part of the board and there aren't any other obstacles (including a lid to the box) in the way. The box is stationary. Eitehr I have to initiate a terminal session and issue M552 S1 multiple times (3, sometimes 2, sometimes 4 usually no more than 4) or by pressing the reset button on the DUET 3 times (sometimes 2, sometimes 4 usually no more than 4) the wifi will work. I have the timing down,
press reset
after a count of 1, blue flash from wifi module
after a count of 3 second blue flash followed by steady blue
all goodif no second flash after 3 count press reset, follow procedure until led is solid
Once on the network, I rarely have issues. In fact I cant recall any issues except for the timeout message from the browser if I walk away for awhile and come back. Browser reconnects as expected when you press connect. I printed from Repetier Server over the network with no issues either, 3 hour print. I can connect anytime from multiple devices. I'ts only at boot (cold or warm)
Everything is configured as it should, I cleared out all networks and started from scratch weeks ago.
Originally I would use terminal with multiple (3 to 5) M552 S1 commands (pausing after the first blue led flash at boot waiting on the second flash and steady blue led from the wifi module).
That was really annoying so out of frustration I tried the reset button and after 3 press (possibly 4, it was a few weeks ago) the wifi came to life just like the terminal, multiple M552 S1 commands. It's easier than having to connect usb, launch termainal, ......
I'm concerned that I'll wear out the reset button or accidentally hit the ERASE button.
There are rare occasions where it works without my interaction, but <10% of the time, possibly <5%.
I use my printers daily so this is an everyday occurrence, multiple times a day since I've been configuring and dialing in the printer and firmware parameters.

@bricor said in Duet Wifi-Establishing Wifi connection requires multiple resets:
Signal is strong
- How strong - when you have established a connection, what is the RSSI reported by M122?
- Which version of DuetWiFiServer are you running? Look in the Settings/General page of DWC to check.
- Please share your config.g file.

my apologies, i should've included them in my original post

I agree, upgrade those first.
If the problem persists, please connect USB, try sending M552 S1 a few times, and let us know what error message it reports when it fails to connect.

As requested I updated to the files linked in the post. Smooth and simple. No change though. at least it's consistent.
-
I've never see this fault reported before, and your reported signal strength looks reasonable. So I think there must either be some incompatibility between your router and the ESP-12S WiFi module, or the wifi module has an unusual fault. If you wish to ask your supplier to exchange your Duet, I will approve that.
-
I bought the board direct. Left over v1.03. Did I make a mistake with the going with the old board, the cost difference is insignificant I sort of feel I made a foolish purchase thinking it was a significant savings.
-
There are no differences in the WiFi support between 1.03 and 1.04 apart from some layout changes to reduce EMI.
-
That was more of a general question and (mostly) unrelated to the issue.
What is typical in this situation, did I really mess up by buying this "deal" direct?
I have to ship the board back to the UK at my expense? (i'm in the US).
or is that a question for Duet3D.com (or is that you?)
-
I'm nit sure if this applies, but I was having trouble connecting my printer to networks other environments other than my home.
Ultimately, I told my Duet to forget all of the various networks that it thought that it knew, and put in only the 3 that I will personally use.
It comes factory configured to a wifi network, which I assume is the one that is used for testing (With a static Ip, 192.168.1.14, if memory serves) and it might have more, depending on what you've set up with M587.
Take a look at the output of M587 with no parameters. I think that it will show you all of the networks that it has stored.
you can then use M588 to have it forget some of those networks. I'd suggest that you tell it to forget everything except "SpicyNacho" and see if that clears things up.
-
@supraguy That's actually one of the steps from the network troubleshooting wiki posted above.
If unable to connect to your wireless network at boot up, try deleting all saved wifi networks with M588 "*" (That is, using an asterix for the network name), then re-adding it with M587. For example, M587 S"networkname" P"password".
-
The basic network stuff has all been addressed. This is seems to be beyond that.
