No. One. Mention. The. Clones.
J/k pm where you have seen them

I thought I had some good google fu, but I can't find anything. Mythological creature, maybe?

I've seen 0.8.5 clones, but nothing for Duet Wifi/Ethernet yet.

1. I have put a build of DuetWiFiServer with sleep disabled (version 1.20beta7-nosleep) at https://www.dropbox.com/s/59s7vfkrf50fe0v/DuetWiFiServer-1.20beta7-nosleep.bin?dl=0. Please try it. The previous build (1.20beta6) is at https://www.dropbox.com/s/djs0p4beitjs60t/DuetWiFiServer-1.20beta6.bin?dl=0.
2. Patel, what make and model of wifi router are you connecting the Duet to?
Devid I try my iPhone it same

My system has disconnected again, 8 min after disconnect I can ping it via terminal fine and it still shows as connected in my router page. Connected via connect button.
Will test again when i get one of the locked out disconnects.

Jarery, thanks for your report. What make and model of router are you using?
Patel, thanks for your reports too. have you tried with DuetWiFiServer 1.20beta7-nosleep yet? Also, what make and model of router are you using?

I have 2, an Asus RT-AC3100 as my main and located 3m away, and an Asus RT-AC66U used as a access point located about 12m away. I get similar results with and without the AP router turned on.
Running latest Merlin Firmware, 380.68_4
Edit:
last disconnect at 2:56, its now 4:03 and connect button will not reconnect. Will take a rebootor reset of wifi module. Cannot ping via terminaledit 2: wifi reset (M552 S-1, G4 S1, M552 S1) showed a reconnect on the paneldue screen but could not connect web browser, a power cycle to the printer did work.

I have updated to DuetWiFiServer 1.20beta7-nosleep and am testing it now.
Curiously, I am not sure that they "print simulation" is working. Its been going for 33mins on a print file that should have taken less than 10mins.
I gave up on the print simulation issue. I guess Ill sort that later.
I have been connected since 8:42pm.
I printed a 14 min calibration cube. Success.
Started a 6.5 hour print at 10:45pmFingers crossed for the morning.

Keegan, which main firmware version are you running? Simulation mode was broken in 1.20b2 and b3 but fixed in b4.

You know what? That is it! I am running 1.20beta2.
I am still connected this morning. It has been over 10hrs now. I am starting the third print now.

Running latest Merlin Firmware, 380.68_4.
Just as a related data point – I have two routers also running Asus Merlin 380.68_4. Once is an RT-N66R (https://www.asus.com/us/Networking/RTN66R/) running just as an AP, and the main router/AP is an RT-AC68P (https://www.asus.com/us/Networking/RTAC68P/).
The DuetWiFi usually connects to the RT-N66R.
I've stayed connected for up to 4 hours. I've not left the printer on longer than that yet.
I've had occasional disconnects, but not enough to bother me yet. If I did longer prints on this printer, it might crop up as an issue more often. If my printer is typically on for 3 hours, I might have one disconnect every third session.
I'm running 1.19.2.

John, when you get the disconnect, are you locked out or can you just click connect to get back?

Hi all,
Here are two new builds of DuetWiFiServer:
https://www.dropbox.com/s/5cp3w947vonp36s/DuetWiFiServer-1.20b8.bin?dl=0
https://www.dropbox.com/s/8k83pw56gefezqm/DuetWiFiServer-1.20b8-nosleep.bin?dl=0
Those of you having issues maintaining a wifi connection, please try the first one (needs DuetWiFiFirmware 1.20b4 or 1.20b6). If that doesn't improve things, try the second one. The recommended way to install these is to download the one you want, rename it to DuetWiFiServer.bin, then upload it through the Settings->General page of DWC.
If for any reason you can't reconnect after installing it, please try re-installing it by sending M997 S2 via USB or PanelDue. I had to do this once on one of my test systems.
Please report your findings here. As a bonus, access point mode is working in this build.

Jarery, I'm sorry, I should have said rename it to DuetWiFiServer.bin. I have corrected the text. You are still running beta7, so you'll need to do it again.
-
John, when you get the disconnect, are you locked out or can you just click connect to get back?
I've seen both types of disconnects, but only the last disconnect was one where I had to power cycle the printer. It was also the only disconnect I've seen since upgrading to 1.19+. The previous disconnects (same timeout AJAX message) I was just able to hit reconnect from the DWC web page.

Of course just after posting that, I had a disconnect.
This occurred after the printer had been running for 2.5 hours. I had done one 1 hour print during this time. I was able to reconnect just by pressing the Connect button in DWC.Perhaps it is time to try that newer firmware, but my disconnects don't seem to happen near as frequently as yours.
John
