@Warstone Yes, I did something similar. See this post.
But having the access point hooked up is just a workaround. Not a solution to the problem.

Okay, thanks for the info!

@dc42 Any suggestions?

So for now (until the wifi module arrives) I have connected an AP which I found in a closet to the second LAN port of my PC, created a wireless network and connected the Duet. Works just fine... as a temporary workaround.

@Dougal1957
Did you replace the router with the sam model (so, was it defect) or did you pick another one?

Already tried that. And I reserved the IP on the router as well to make sure it is free.

@droftarts
Yes, actually seems like something @dc42 might be able to fix. I think I will try the wifi module in the meantime anyway.

@bearer
That's not possible with this router.
So my only option is probably to buy an M.2 wifi module for the PC and use this to connect to the Duet run in AP mode. But first I would like to double check if the module is compatible to the Duet.

I would probably pick the Intel 9260NGW which is a Wifi 2.4/5Ghz + Wifi 6 + BT 5.0 chipset. Any experience with this chipset connecting to the Duet AP?

@bearer said in Cannot connect Duet Wifi to new Wifi Router:

see if the new one has some ultra mega max 2000 multimedia streaming extensions and try fixing the channel width to 20mhz and setting bgn mode to a lower common denominator, apart from that sounds like you might be better off briding the Duet to the old router?

Limiting to 20 MHz didn't make any difference.
The mode cannot be changed to anything but "Mixed 802.11 g/n" for the 2.4 GHz wifi on this router.

Edit: I cannot use the old router as an access point because I have to send it back to the ISP soon.

It's a so called "Vodafone Station".
To be precise it is the ARRIS Touchstone TG3442DE.

The firmware gets updated by the ISP automatically.

@bondus
This is so frustrating. What is the use of standards if no one sticks to them?

@bearer
Tried same SSID and PW on the new one. Yes

I don't think it is a hardware problem with the board. This would be a strange coincidence cause it worked until I changed the router.

I will power up my old router now an check if the Duet connects to it.

Edit:
Connecting to the old router works just fine.
This has to be some kind of incompatibility...

Yeah, but to be honest, this should really not be a thing.
The physical distance between the router and the Duet is maybe 0.5m. It's literally just this one wall in between.

I will actually try to remove the special chars from the wifi SSID and password now to see if this could be a thing.

Edit: No success

Some more information on the 2.4GHz wifi:

SSID: GarMir 2,4GHz
SSID broadcast: off
Security: WPA2
Wifi mode: Mixed 802.11 g/n
Channel: 11
Bandwidth: 20/40 MHz

By the way: Sometimes I can see the Duet in my router status as

Name: unknown
IPv4: 192.168.0.37
IPv6:
MAC: 2C:3A:E8:0B:17:0F
WiFi: 2.4GHz

with full signal strength.

It's channel 11 fixed.

M122 always reports

Network state is changing mode
WiFi module is trying to connect

Doesn't seem I can get a report in the very short time frame, when a connection is established.

But I am shure, the signal strength is very good. This can't be the issue. I can easily establish a very good wifi connection two rooms further from the router with any device.

Ok, so I updated the frimware and Wifi server:

About the physical conditions:

The printer is right next to the router (ap) with one wall in between. The signal strength should be easily sufficient with the 2.4GHz wifi. I even get full 5GHz signal strength right next to the printer on my phone.
There are many wifi signals around here. It's a pretty crouded place. But I made sure to use the wifi channel that has the fewest SSIDS. Currently it's 2AM and there should be near to no interference.

I will go into detail about this if the firmware update does not solve the issue.
But I've got a question about the fallback update procedure. There is no "iap4e.bin" in the repo but the guide tells me to copy it over. Should I simply leave the old file in place?

@bearer
Didn't help unfortunately.

@droftarts
As mentioned by @bearer , this should not be an encryption issue. Router is set to WPA2 and encryption mode is AES.

@droftarts said in Cannot connect Duet Wifi to new Wifi Router:

It would be good to update your firmware to the latest RRF2 version, 2.05.1.

I will try this next.

@PaulHew
See my first post again "but I also tried with a broadcasted SSID"
And no, the SSID was not the same and I even tried using another SSID.
