Duet 3 Mini 5+ version 3.3beta3

Okay, so it's not that, though would be worth updating from beta to release candidate (3.3 RC1). Update the DuetWiFiServer to 1.26 at the same time; it fixes a minor bug whereby it was transmitting a small amount of extra unwanted data on the wifi module SPI interface (says @dc42, though I doubt this is the issue).

For pi network bridge, see https://www.raspberrypi.org/documentation/configuration/wireless/access-point-bridged.md
However, I was slightly wrong; the Pi would be wired via Ethernet to your hub. However, this should test if the Duet is at issue.

What do you mean by hub? The duet or my modem?

[droftarts]

@dessiverse Sorry, by hub I mean your xfinity router. I assume it's got at least one ethernet port! So you would have an Ethernet cable going from your xfinity router to the raspberry pi. The RPi would allow your Duet to connect to its WiFi, and bridge the connection between the WiFi and Ethernet.

@dessiverse, FWIW I recall some time ago that a Duet WiFi user was unable to get good WiFi connectivity from the Duet on WiFi Channel 1, but switched to another channel (6 AFAIR) and it worked much better. However, that's no help to you if your ISP won't allow you to change the channel.

I'm finding a bunch of guides that do the reverse of this. Not having so much luck on the other way around.

[droftarts]

@dessiverse The guide I linked to earlier, https://www.raspberrypi.org/documentation/configuration/wireless/access-point-bridged.md does the right thing:

In the above image, the 'Router' is your xfinity box, which is connected by Ethernet ('LAN') to the 'RPi', with a wireless connection to the 'Laptop', which is where the Duet 2 WiFi would be.

Edit: Just checked, your Xfinity TG4482A should have 4 Gigabit Ethernet ports: https://www.xfinity.com/support/articles/broadband-gateways-userguides

@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?

Yes. It should give you an IP address in the same range as the other connected devices, though.

@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.

I didn't read the whole thread so apologies if this was already in but ESP module is nice and cheap but does not play nice with all wifi hw out there... There are AP's that ESP will just not talk to. I had terrible issues with few AP's (one was some PRC noname repeater, one was tp-link dual something, and one was some xfinity router) ... the noname one I gave to a friend who use it for travel, works great but just don't work with ESP, no matter what you do, xfinity I tried everything also, does not work, got rid of it, tp-link, I changed the original firmware with openwrt and it not works ok with ESP modules ... I see you are using xfinity, might be impossible to solve the problem (maybe, dunno, maybe someone can), the easiest solution is to have second, el cheapo, access point that works ok with ESP modules connected to that xfinity with it's own SSID that you can use for your "internet of things" that's using ESP in huge percentages..

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.

[dc42]

@dessiverse is the Nighthawk also using WiFi channel 1 ?

[DessiVerse]

@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.

[Phaedrux]

And that's with M552 S1 in config.g?

[DessiVerse]

@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.

@dessiverse said in WiFi Unreliable:

Here is the config.g file
; Configuration file for Duet 3 Mini 5+ (firmware version 3) ; executed by the firmware on start-up ;

The config.g was posted there ^

Ok, but we're also at 113 posts in this thread now, so can be hard to keep track and I still wouldn't know if it's current, so I'd still ask again.

Might want to try something like netspot or some other wifi analyzer tool to see what kind of a wireless network environment you've got
