Won't connect to Wifi (but it used too…)
-
Hallo,
if have similar Problems with my duetwifi. After 4 month of usage the duetwifi lost the wifi connection from time to time. Now the wifi seems to run but the machine is not able to connect. If i ping the machine only the first ping works.
This look like this.ping duetwifi

It could be a failure of the WiFi module. But I think it more likely that the Duet is competing with other devices to be heard by the router. If you move the printer closer to your router, does it connect reliably?

Had exact same thing - did you try clearing all of your browser cache?

Hi David,
i put the printer as near as possible to the wifi router so the signal strength goes up to -30dBm. I also disable most of our wifi-device but nothing happens. If i ping the machine only the first ping received an answer all other packet are lost. Is it possible and does it make sense to connect an external antenna? -

It does sound as though the wifi module may have developed a fault, or else you have hit an obscure bug i the wifi firmware. The two courses of action I can think of are:
- Try the new 1.19 beta6 release of DuetWiFiFirmware and the associated 1.09 beta 1 release of DuetWiFiServer (see https://duet3d.com/wiki/DuetWiFiFirmware_1.19beta for important information); or
- Replace the WiFi module

I got the same weird problem. I used DUET wifi 1 month back. After that I used the 3d printer today only. Initially the DUET Wifi was not connecting. I found this thread and thought the Wifi module is not working. I moved my printer closer to the router and used pronterface. I reset the wifi by M551 S0 and again used M551 S1 and found the signal strength=-48dBm.
It gave the IP of 192.168.0.5, but nowhere I was able to connect to this IP.
One of my PC's was connected to the router through ethernet cable. From that PC, I used Chrome browser and typed 192.168.0.5, and voila.. It worked. I am surprised by the behaviour of DUET Wifi. Eventhough the Wifi board is very good, like others we are also facing too much problems. Next we should go only to the Duet Ethernet.

I solved "my" Problem!
After I almost went mad, I restart my Fritzbox 7390 (in Germany a very popular Wifi router) the first time after 3 months. I can not believe it but the DuetWifi-Board is now easily accessible again. Can it be that the Wifi router masked the DuetWifi board as unsafe? -

There was a case recently of a router apparently blocking the MAC address of a wired Ethernet connection. So this does happen. My best guess is that if you get an IP address conflict, the router blocks one of the two Mac addresses involved.

I use fixed IP addresses for all devices on my router. But after rebooting the router i see a new firmware on it. Maybe the automatic installation of the router does not work reliably. A hardware reset seem from time to time not to harm, please excuse the stupid error.
-
It's not a stupid error, IMO we have every right to expect routers to just work.

Hi guys,
have a similar problem with my new DuetWifi board.
Connects fine when powered up and is accessible. After a few minutes - e.g. 40 min into a print - it can not be pinged anymore or accessed through the webpage. Restarting the machine brings it back immediately.
When I enter M551 S0 on the PanelDue Console I get Wifi Server disabled, when I enter M551 S1 however I do not get any readout on the console. Not sure if that is normal or not (for the Panel).Once additional point: I used the accesspoint method to get it connected and left the network settings in the reprap configurator empty (only entered the machine name). Could that be the issue?
Help is very much appreciated.
Thanks,
Eric -

It's M552 you need to use, not M551.

Thanks. To update, my issues went away after I updated the router. Happily pushing stuff over to the duetwifi now
