Turned off the duet and went to sleep

"Day 2"

Had a thought after browsing the forums, nothing specific I was reading but thought, "what happens if I turn on the duet but not immediately connect to the DWC?"

So the journey continues

Start ping
Turn on duet
Connect USB
Turn on debugging for P1 (Network) and P14 (Wifi)
Issue M122 for start, all seems good

Duet is pinging but noticed (again) that it is erratic in its ping times to an AP that is in the same room. At cyclic times, noticed that there is a string a ping timeouts for 5 pings (essentially 5 seconds) then immediately recovers.
There is consistently in this pattern.

After 4+ hours, I go to the DWC
Network debugs start throwing this out

I take it this is normal
About 5 minutes into just browsing the DWC

Some observations: Remember the erratic pings and it timing out every now and then?
So when the ping drop happened, DWC dropped (and never came back like the day before)

Issued M122 again
- Network is running 99% but in "ready" state
- "noresp" increasing
- Socket states back at "6 6 0 0 0 0 0 0"

So I let it sit in this state for hours
Pings never came back either.

Other noteworthy things
- Have not tried resetting the wireless with M552 commands yet. Just wanted to gather information to try to be helpful data gathering.
- Wifi blue light has been steady the whole time, never was it ever blinking (tells me it stayed connected to the AP, M122 commands confirm this)

Don't know what to do next, so thought I'd post since I'm at the latest (stable) version of all firmware.

This is not a production printer, I'm just a hobbyist, so I can try things out. Will take me a couple days at a time to respond if I need to try something.

@trd87t Thanks for the extensive report. Could you please:

send M586 and post the response, to see what network protocols are enabled? Disable any you are not using, eg FTP, Telnet
check the list of stored WiFi networks, by sending M587, looking particularly if there are any duplicate entries, with different capitalisation.
post your config.g.
have a look through the WiFi Troubleshooting page, to see if any of it is relevant.
is the SD card the same vintage as the printer? It may be worth trying a new SD card (we recommend using at least a Class 10 card now); see https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

If nothing helps, @rechrtb will need to take a look at it.

I have read through this initially. AP is in same room as Duet with a -35dbm signal strength. The room in which it is in, is not near typical interference appliances, etc. The duet does stay online and pinging until the DWC is accessed.

The SD card is of the same vintage. I can try a new card but will take a few to get it going, I will attempt this weekend.

Got a new SD card over the weekend (SanDisk Ultra A1 HC).

Formatted according to the instructions on https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

Still seeing the issues.

Going to test out a couple things (that are probably not going to do anything but I'm trying anything at this point).

Going to boot the duet and connect to DWC and let it sit on the Dashboard, see if it loses access just sitting there.
Going to clean up the SD card. It has old firmware from RFF-1.18 days
Since I have multiple SD cards now, going to install RFF3.3 with the older Wifi Firmware (prior to 2.01)
If stable, keep upgrading stable releases until it breaks?

DonStauffer

@droftarts I didn't read all of the original posts, but it sounds like what I've been seeing. WiFi suddenly disconnects unexpectedly. It usually reconnects about 15 seconds later, but I've been dumped out of whatever macro folder I was looking at, and if I was editing, I'm dumped out of the editor. Everything functions fine until the next time it happens. M122 is below. I have replaced the SD card recently and this problem predates it (it's been happening for months). I also occasionally get WiFi failures at power on, but not frequently. Cycling the power fixes that.

When this happens I sometimes wish I had a wired ethernet connection to fall back on (or just use most of the time, but still have WiFi available). I've been considering replacing the Duet2 WiFi with a pair of Duet3 Minis, and I was wondering if one can have WiFi and the other ethernet and thus give me the choice.

RRF3.4.6 WF1.27 - good

Much better ping times and consistent

@trd87t @DonStauffer

Hi, I've been looking into some improvements to the WiFi firmware in terms of connection stability. Below is my initial build with those changes. If possible, please do try it out and let me know if you still encounter issues.

Note: After firmware update, please confirm M122 outputs wifi firmware version as 2.1.1beta1.

DuetWiFiServer.bin

DonStauffer

@rechrtb I'll try it! Just installed RRF 3.6 alpha 2, which seems to work fine.

DonStauffer

@rechrtb I have it installed. I'll let you know if I have any disconnects.

rechrtb

@DonStauffer Thank you!

rechrtb

@DonStauffer By the way, is the disconnect something you can sort of 'induce'? Because, if you can, please do try it on this new firmware.

DonStauffer

@rechrtb I haven't seen any way to make it happen. It may be my imagination, but I think it happens more in the afternoons than mornings, if that makes any sense.

No trouble since last night's update to RFF & WiFi.

rechrtb

@DonStauffer @trd87t Hi, I just wanted to ask if you encountered issues with the beta firmware build so far...

DonStauffer

@rechrtb The WiFi still disconnects unpredictably. Alpha firmware and beta WiFi didn't make it better or worse. I don't see any pattern except it seems more in the afternoon. I was assuming it was an interference problem, although other houses are at least 100 feet away here, and the Duet is about 10 feet from my router. But with increasing bandwidth use for WiFi I figured interference.

The biggest problem is if I'm editing a macro or something it drops me out and unsaved changes are lost. If I had the ethernet board I'd just have gone with a wired connection.

@DonStauffer I see. Sorry to hear you're still encountering issues. When the issue occurs, is DWC open in multiple tabs (same or different device). Or perhaps a transfer is going on? Also, this doesn't happen on 1.27x wifi firmware?

DonStauffer

@rechrtb Nothing is necessarily happening, and no, not multiple tabs. Sometimes I even go out of the room briefly and come back and I see in the console log it disconnected then reconnected. Sometimes I see it happen. Usually it's out for anywhere from 20 seconds to a minute or so.

I don't remember the firmware version for sure but I'm pretty sure I was on the latest released version, and now 2.1.1beta1.

console log it disconnected then reconnected.

Oh, do you have what that log says? Also, do you happen to have a mesh/multi-AP setup, and the router you mentioned just happened to be the closest one?

@rechrtb said in Wifi/DWC Disconnecting with RRF3.5.2 on Duet2 Wifi Hardware:

mesh/multi-AP

Only one router in my house. I think the log entry just said it lost connection. Next time it happens I'll copy the log entry and post it here.
