Canon Pixma printer will not connect to the router

[Caer_luel]

I bought a TS7750i, and it will not connect to the Smart Hub 6 plus. if I try WPS it just times out, I’ve tried caring directly, and the printer can see the router, but after I enter the password it fails to verify, I have enabled the comparability mode and that has not helped ,

any ideas please ?

My Brother laser printer dropped off the WiFi this week.

Printer network diagnostics printout said EE Smart Hub Pro was WPA3 with TKIP / AES encryption but printer would only allow WPA3 with AES encryption.

Changing WiFi security from WPA3-Personal-Transition to WPA3-Personal, in the Smart Hub Pro's management interface allowed the printer to connect.

I wonder if EE pushed a firmware update to the router recently which altered the WiFi settings

@Caer_luel There is a hidden wps button option as WPA3 does not allow the use off wps connections! Not sure if you can see it app wise, but you will be able to get to it via the web interface!

@therug1 - this sounds all sorts of wrong!

Firstly, running the hub using WPA3-Personal is not typically a good idea. Whilst WPA3 became a mandatory part of WiFi certification at the turn of the decade, there are plenty of WiFi devices in circulation that simply don't support it and will outright refuse to connect to a WiFi network that's configured to use it.

Second, is the point made by @JimM11 - WPA3-Personal does not support WPS. If you configured the hub to use WPA3-Personal and was then able to connect the Printer using the WPS button then something is wrong.

The Smart Hub Pro defaults to WPA3-Personal-Transition out of the box.
