duet2wifi not pinging from windows 10

tekstyle

it has been working for a few months but now just stoppped. when I turn on the printer, the paneldue shows that it is connected to my wifi at 192.168.1.138. i can see it on my device list in my router's dashboard. however, I can not load DWC. I am also unable to ping it from cmd prompt using "ping 192.168.1.138".

I find it very weird that i can see that it is connected, but would it not communicate? I have not changed anything on the machine since it worked last. Is there a way I can control it using DWC through USB since this is not the first time I have had issues with wifi connection. my other machine that also uses a duet2wifi board loads up no problem on the same network using the same windows machine. also able to ping it no issues.

When panelDue is still working, the SD-card should be OK, but it's worth a try to swap the card with the other printer, just to see, if www folder is still OK.
You can also write macros and copy them to SD-card. Then it would probably help to stop WiFi and restart it with two macros.
That way you don't need to use USB and YAT.

You can manually reset the wifi module if you have console access via USB, or a PanelDue. 
Send M552 S0, to disable networking, followed by M552 S1 to enable networking.

Good luck

@o_lampe

@phaedrux
ah dang it. i think i am already on the latest.

I put the machine in AP mode and it works. maybe its my stupid router. i have a linksys velop tri band with 5 mesh towers.

Phaedrux

Make sure it's forced to use 2.4ghz for the Duet.

tekstyle

@phaedrux it doesn't have an issue connecting to the router. just communicating with it. i see the ip device on my device list and it' says 2.4ghz

Phaedrux

Does the router have wireless client isolation enabled?

tekstyle

@phaedrux never heard of that. so i guess not.

tekstyle

@tekstyle if you are referring to guest mode, i currently have it connected to a guest wifi. it still dont work. there is nothing in it except my PC, duet, and a rasp pi

MintyTrebor

@tekstyle I think @Phaedrux has got this right. If you look at the documentation for guest access Wi-Fi on your router:

it states it restricts access to other devices on the network...

There may be an option to disable this (look for client isolation) but that not be an option available - a lot of commercial routers lock down advanced options...

You may have to move your equipment over to the main Wi-Fi network (and you should check client isolation is not enabled for the main network too)

tekstyle

@mintytrebor ah ok, i get your point. i can always just put them back on the main network. however, that was where all my issues began anyways. creating the guest network was an attempt to fix it

my computer can communicate with my rpi just fine over guest wifi

MintyTrebor

@tekstyle Reading through the post history, if it still doesn't work when you put it back on the network you need to start checking the other variables:

Pinging the board - If you are unable to ping the board, turn off windows firewall - does it work then? Can you ping the board from another device like the SBC?
Router - I believe you router offers multiple wifi bands, check that the you are able to talk to devices across the bands (2.4/5), or even force your PC to connect to the same band as the duet.

The only other thing I can think of trying if your running win 10, is to turn on the hotspot capability and connect the duet to the hotspot network
(https://support.microsoft.com/en-us/windows/use-your-windows-pc-as-a-mobile-hotspot-c89b0fad-72d5-41e8-f7ea-406ad9036b85) if that works then you have proven your network/firewall is at fault.

Until you get a ping nothing else is going to work. The fact that you can get this to work in AP mode suggests its your network config that's causing this issue.

Hope this helps

@mintytrebor
i tried setting up a mobile hotspot on win10 . it worked for a bit then didn't. the computer is sitting right next to my printer. i haven't messed with firewall yet but i think it is set up in a way that i can access anything within the network freely. ill look into it .

MintyTrebor

@tekstyle The fact it connects and then drops on the hotspot, is leading me to think it is the duet board or config issue.

As you stated earlier, you have another duet board based printer which works fine, and I think you have done enough to confirm your networking is not at fault now.

Other than changing the sd card & a new install/config, there is very little else I can think of to try.

Phaedrux

So you have two duet wifi boards? One will connect, but the other won't?
