@phaedrux config.g has M552 S1. I run the others to disable the WiFi then re-enable and connect. That's just what has worked in the past.

The config.g was posted there ^
@dc42 It is not. I actually had to return that router as it crapped out overnight. Netgear support wasn't quite sure what happened. I ended up getting a linksys something and I set the channel manually to 6 but it's being quite finicky.
After a couple of refreshes, I was able to get it to work, and it's being consistent at this speed. 
It does seem that I have to manually run M552 S-1; M552 S0; M552 S1 a few times to get it to connect to the router correctly. Not sure why that might be.
I had purchased a Netgear Nighthawk router, and the router is working great with it. Annoyingly, I still don't know what the issue was exactly with the Xfinity Modem / Router combo. Given the scale of Xfinity, I think it is something that should be looked into going forward.
@droftarts An Xfinity technician is coming over as some point today to check the network for any issues regarding the duet and my extenders, see if that'll help in anyway.
@droftarts I just finished setting that up, going to test in a few.
To my understanding, it creates a new network that you connect to that is a bridge between the two networks?
@droftarts said in WiFi Unreliable:
The RPi would allow your Duet to connect to its WiFi, and bridge the connection between the WiFi and Ethernet
I'm finding a bunch of guides that do the reverse of this. Not having so much luck on the other way around.
@droftarts said in WiFi Unreliable:
the Pi would be wired via Ethernet to your hub
What do you mean by hub? The duet or my modem?
@droftarts said in WiFi Unreliable:
Also, not sure what has changed, but the latest version of DuetWiFiServer.bin shipping with 3.3RC1 is v1.26, you're on v1.25. May be worth updating to that.
The firmware I'm currently running is:

That appears to be the versions you're referring to, no?

@droftarts said in WiFi Unreliable:
No, it's just connecting the Duet WiFi to the Pi WiFi, then the Pi WiFi connecting to the xfinity WiFi. The Pi bridges the connection between the two. There should be guides around on the Pi side to do this.
This sounds like it can be really helpful. I'll have to research this.
@droftarts Is using the pi as a network bridge SBC mode?
Give me a second to post a reply to the rest.
@stuartofmt the packet loss is consistent across multiple computers.
Here are the "advanced settings" that I can change from the router:
My biggest frustration with this is the lack of any phone or priority support. The amount of time wasted "troubleshooting" this is costing more than it would be to just buy a different board and call it a day.
To attempt to wrap this up; when using SBC mode is it possible to combine SBC with Octoprint in anyway?
It still makes no sense to me at all that SBC would run fine, all other devices run fine, yet the duet has a million network issues but somehow it's my modem that's the issue not the duet.
I'm working with my ISP today to try to get any more information that I can. I'm still very much on the fence of it being a router issue given that the problem is only happening with the Duet. To me, the duet is having an issue with the router, not the router having an issue with the duet.
Especially given that running SBC mode there isn't an issue.
@phaedrux said in WiFi Unreliable:
What I suspect might be happening is that the router is misidentifying the capabilities of the Duet and initiating band steering trying to force it over to the 5ghz
So I know this isn't happening because I did separate the two networks for one test, and had the same issue.
@phaedrux what other information do you need? Is there anything else I can do from the Duet's end?
I'm still working with the ISP to try to change the signal channel.
@phaedrux Wait, if it's a problem with the channel wouldn't the signal be worse? When I ran the M122 tests the signal showed it was fine in all cases, even when it was being slow.
@phaedrux After reaching out to the internet provider, customers are not allowed to change the network channel manually for some reason. Which doesn't make sense.
However, it's really odd that the duet would be restricted to channel 6. For the price the duet is, I wouldn't expect such a weird design flaw.
@phaedrux This is the model info
This is the 2.4GHz settings. Some of them.
What settings are you looking for specifically?
@phaedrux I would like to go the ethernet route. I had already consulted filastruder regarding this and they said duet has to authorize the exchange. I will reach out to them and send them the forum.
@dc42 Is there a way to confirm for a fact the antenna is in use and it's not just being ignored? I tried another antenna with a wider range and it's having the same issues.
@stuartofmt The reason why I'm very hesitant to say it's a router issue is because I have no issues communicating between any devices on the network besides the duet. The duet is the absolute only one to have any issues, so it doesn't make sense to ignore all other devices and say it's a router issue because of this one device. I do ask again, is there a gcode to check that the antenna is working as it should? Because that right there could be the issue.
EDIT: I also want to note I tried inSSIDer and saw that both my networks, 2.4 and 5GHz, are running on the most unused channels in the area. So that's probably not it either.
@dc42 I'll have to try to see if I can change just the 2.4GHz channel. Is there a list of recommended channels?
