Mini 5+ Wifi Problem Revisited

I have the same experience with my Duet 2 and wifi server 1.27. I lose connection constantly on anything beyond 1.27. I think it is likely my very old router that I use for the printer network.

Interesting.

My WiFi Access Point and my Router are both new products from Ubiquiti.

I do have an older WiFi Access Point from Engenius that I could setup just to test if the problem is with the new Ubiquiti WiFi Access Point.

As to the firmware, that only item I changed that "bricked" the WiFi connection is the Duet WiFi Server .bin file.

And I can connect via USB so M991 S1 should work.

Since the replacement Mini is working with 3.5.4 and 1.27 perhaps I can figure out the correct set of steps to duplicate that set of firmware on the old Mini and restore it to usefulness.

Thanks much.

I was able to copy the 1.27 WiFi file to the Mini 5+ SD card and started the update from the USB connection - all went fine and WiFi connectivity was restored.

I located an old Engenius WiFi Access Point and configured it for testing the WiFi connection to the Mini with the 2.2.0 WiFi firmware.

I again updated the Mini using the 2.20 WiFi firmware file.

And, as before, I can connect but it shortly fails requiring a M999 to get another short lived WiFi connection.

Oddly even when the connection under 2.2.0 fails the USB connection reports it is still connected to the Access Point.

So while the short lived WiFi connection was still working I again uploaded the 1.27 WiFi file and it completed the update and persistent WiFi connectivity was restored.

I know that officially there is no WiFi problem with 2.2.0 but it certainly is easy here to demonstrate the 2.2.0 does not work reliably while, with the same hardware and 3.5.4 firmware and DWC, the 1.27 version does work just fine.

So both Mini 5+ boards (v0.5 and v1.0) have 3.5.4 firmware everywhere as well as 3.5.4 DWC with 1.27 WiFi and both are working fine.

I've got a brand new 6HC board with the WiFi module. I'm going test it when I get a chance to see how it does in regards to WiFi connection reliability vis-a-vis WiFi firmware versions.

For now I am a happy camper with fingers crossed.

Hi,

Just FYI.

I did some more testing.

I setup a 6HC with WiFi module on the bench and it works fine with Duet WiFi Server 2.2.0

All four of the Mini 5+ units required 1.27 to work reliably, regardless of the brand of WiFi Access Point.

So my problem is solved even if 1.27 is not the "official" version.

@fcwilt we’ve asked @rechrtb to look into this issue. If he comes up with anything, it would be good if you could test it?

More than happy to test.

I have two 6HC boards with the WiFi module (one on the bench, one in a printer).

I have four Mini 5+ boards (two on the bench, two in printers).

For WiFi Access Points I have Ubiquiti U6 PRO and EnGenius EAP1300.

The Ubiquiti are recent units and are still being sold. The EnGenius is an older unit, no longer sold, but it was always reliable. I can get other APs if that becomes necessary.

@fcwilt have you tried release 2.2.1 of the WiFi firmware?

We also have a draft release 2.3.0 which I can make available to you if you would like to test it.

Currently I only have two printers up and running, both using 6HC boards.

Both are showing version 2.2.0.

I can easily setup a Mini on my workbench but it would have no hardware connected.

I would be happy to try both 2.2.1 and 2.3.0.

Even using the Ethernet connection on the two 6HC based printers is leading to occasional lost connections.

@fcwilt do your machines have PanelDue screens connected? If so, what firmware version are they running?

We are aware of an issue whereby in some machine configurations running firmware 3.5.x the object model becomes too large for both DWC and PanelDue to fetch it simultaneously. One of the symptoms is dropped network connections. In version 3.5.1 of PanelDueFirmware we made some changes to mitigate this, and in RRF 3.6 we made some more.

Both of the PanelDue units are running firmware 3.5.1.

I am not running any version of RRF 3.6 as I do not install alpha/beta/rc firmware.

I will update the WiFi firmware to 2.2.1 and see if changes anything.

If you can get 2.3.0 to me I will test that as well.

Thanks.

Where can I find the versions 2.2.1 and 2.3.0 for the WiFi server?

Thanks.
