No networks found after 1.19+4 upgrade

mrwaug

with the number of people having problems with network communications after upgrades, i would think that there is a problem somewhere in the instructions, possibly assumptions that we know everything. it appears that step one of loading the Duet Web Control can be done with DWC, but nowhere do i see a place to replace the /www folder, so i remove the SD card and replace and rename the files accordingly. i then send the M997 S0:1, which downloads fine, but i have to reboot the duet wifi module, after that everything works fine until i try to get the access point.

m98 p/macros/setnetwork
SENDING:M98 P/MACROS/SETNETWORK
WiFi module started
m587
SENDING:M587
Remembered networks:
Coyote Delta
COYOTE DELTA
m552 s1
SENDING:M552 S1
WiFi reported error: no known networks found
Wifi module is idle

i dont know what i am missing, i have tried this procedure several times including a m997 s0 then a m997 s1. if i try the update firmware button and the DWC it losese connection right after the firmware finishes updating.
as soon as i revert back to1.18, everything works fine. Could you rewrite the procedure a with a little more detail involved and include what to do if a certain step does not work. It would probably save you a lot of time having to answer all of the thread regarding network connection issues.

The error "No known networks found" means that the WiFi module couldn't find a wireless network with name either Coyote Delta or COYOTE DELTA. Is one of those really the SSID of your WiFi router?

To me it happens exactly the same as arwaug. I can not connect to my ssid after updating. To return to 1.18 all correct.I've tried it all afternoon, several times but I have not been able to.

This might be where the confusion comes from. Coyote Delta is the machine name and reprap the password set in the config.g file, which is what I used to set up the SetNetwork macro, is this wrong?

M587 when called should your home wifi SSID, it looks like you programmed in your machine name instead of your wifi access point and password.
This link may help: https://duet3d.com/wiki/Getting_connected_to_the_Duet_WiFi
look at the Connecting to your access point using firmware 1.19 or later section
Connect via USB and pronterface or the like and:
You can use M588 to erase the coyote delta , just send M552 S0 and then M588 S"COYOTE DELTA" and the same for the lower case to delete them

And the send M587 S"your-network-ssid" P"your-network-password"
and lastly M552 S1 and it should connect to the strongest network if you have entered more than one

Also I reserve the right to be completely wrong if I am but it worked for me

Should work with v1.19+4. Installed that release last night and connected without issues.
Best take your smartphone and do a wifi survey. Use the name exactly as shown (upper case/lower case).
Survey tools I use on android : IP tools for more technical info and wifi analyzer (gives a graphical overview)
