DWC connection problems
-
@Haggan90 Everything you did in this thread https://forum.duet3d.com/topic/13393/can-t-connect-to-dwc makes it look like it's a problem with your network. But lets start this thread with all the information we need. Connect to the Duet via USB, and using YAT, please post:
- Response to M122 (shows firmware version, wifi firmware version, connection information etc)
- As suggested by @bearer in the other thread, send
M20andM20 P"/www"to the Duet, which will list the files on the SD card in the gcode directory (not necessary, but good to see if it works) and the www directory (to check you've got the web server files). eg the response from mine is:
M20 P"/www" GCode files: "css","._css","js","._js","favicon.ico.gz","._favicon.ico.gz","reprap.htm.gz","._reprap.htm.gz","language.xml.gz","._language.xml.gz","fonts","._fonts","html404.htm","._html404.htm","dwc.json","index.html.gz"- Describe how your WiFi is set up (router make and model, whether you connect directly to it or use range extenders)
- Check the router's configuration that it does not 'quarantine' WiFi connections from the network, both for the Duet and your PC (if it's connected by WiFi)

How do I check that? If I check the "client list" in the router I can't find the Duet there.. -
And now miraculously, I can connect to it again... But this is very annoying >.<

Aaarrgh! Please setup YAT to use <LF> as the end of line character. Go to "Terminal" Menu -> "Settings" -> "Text Settings" -> "EOL sequence:" set to <LF>. Then output will be more readable!
Anyway, edited highlights from the M122 command:

From https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors
Values in the range -30 to -50 are good, -50 to -60 is OK, -60 to -70 is marginal. Anything below -70 is weak and likely be unreliable.
Keep an eye on these settings if you have further disconnections.
Have a look at your router. You're going to have to investigate this yourself, but I'd start by making sure the firmware was up to date. What firmware version is it running? Latest seems to be 3.0.0.4.382.51641 2019/11/05. See https://www.asus.com/uk/Networking/RTAC66U/HelpDesk_BIOS/
That the Duet is accessible, I'd think the setup was okay, but perhaps the Duet keeps dropping out and the router is reassigning a new IP address. You could try setting a static IP address by updating the stored SSID and password with command M587 https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M587_Add_WiFi_host_network_to_remembered_list_or_list_remembered_networks
M552 S0 ; set network module to idle M587 S"AF-House" P"[your_wifi_password]" I192.168.1.189 M552 S1 ; turn wifi back onOtherwise, what's the environment like? Close neighbours with WiFi may be drowning out the 2.4GHz signal. Strong radio signals (I have a baby monitor that kills my WiFi) can also cause disconnections. There's probably a whole host of other factors. The page I linked earlier https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors also has lots of suggestions.
Let me know if any of that helps!

maybe run just
M587to see which networks you have stored and are connected to? -
@droftarts Thanks alot for an amazing reply!
I will try and set a static IP and somehow boost the wifi signal. -
@Haggan90 As @bearer suggests, do you have other networks registered on the Duet? Send M587 to see them. Best to have only one network, then it won't try to connect to anything else. You can delete all saved SSIDs by sending (via USB and YAT is easiest):
M552 S0 ; set network module to idle M588 S"*"Then just add the one you want, as my earlier post.
Edit: I'd still check/update the router firmware first.

just realized some routers only show dhcp clients; others are able to also show associated wifi clients - if you're using a static IP that may explain it
nownot showing up -
I am new to Duet. Have a Duet 2 WIFI
Started working on everything - getting hooked up.
Started with YAT getting WIFI and then the DWC running.
Used DWC to update firmware and config file. All good.The I was loving the Web Based Configurtator tool, generated customer configuration updates and installed them and now I have no DWC WIFI connectivity!
Using YAT IP is good looking at my router there is a connection

@Dave-O Probably best to start your own thread. But off the cuff I would check your SD card for a /www folder to ensure that you have the DWC files in there.
