Duet Wifi Wlan vs WPA2 = Connection Error
-
As the titled say: i got a connection problem with my Duet Wifi. A friend and i configured the Board and linked it up to his home w-lan without any problem. We do all the necessary things to get the printer started and it worked.
When i get home, i just entering the commands as shown:
M552 S-1
M552
M552 S0
M552
M587 S“My SSID“ P“ My Password“
M587
M552 S1After that i get connection error (see protocol below). Several attempts later I changed the SSID and passwords but nothing worked.
So I decided to set up a WiFi HotSpot with my Galaxy S7 and zoom … the Duet connected to the Smartphone after 3 Secs.
So I tried to connected back to my home Wifi and get the typical message: error
I retry the Smartphone which was working fine and then decided to try a connection to my neighbors WiFi and again: zooom connection after 3 secs (ask for his Password and SSID)
I went further and enabled MAC in my Router Option … nothing … the only way for connecting was to disable the WPA / WPA2 protocol in my router and surprise: we get a stable connection after 3 secs …
Hopefully someone has a idea to fix this, I use a Vodafone Router with the newest firmware. Other devices as our smartphones, the normal HP printer and Smart- TV / TV- Stick work still fine with the router settings.

i think this is the second report of an incompatbility with vodafone routers. no solution as far as I know.
Doubt its relevant, but any special characters in the key?
-
No, just a standard Key like "A1234567b" (was my testing Key)
-
is the SSID hidden? that can sometimes cause issues
-
WiFi reported error: Timed out while trying to connect to DWTN
it wouldn't try to connect to DWTN without it specified on the M552 command if it was hidden
-
SSID is broadcasted
The Router know the MAC of the Duet
The Duet is remembering the SSID (and Password)Executing config.g...Error: M587: Failed to add SSID to remembered list
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled

@Warstone as @bearer said, there seems to be an issue with Vodafone Station routers. This may be related to an obscure bug in the Duet WiFi firmware. See this thread https://forum.duet3d.com/topic/14993/cannot-connect-duet-wifi-to-new-wifi-router
Ideally, use an access point to connect for now.

Hooked up my old D-Link Wifi router between the Vodafon router and my PC. It slows down my connection a bit, but the Duet is connecting without any problems to the D-Link instead of the Vodafon Router.
