PIXMA MP560 My printer won't prompt for a password

[angelambell]

I recently changed internet providers and since having the new service my MP5650 won't prompt to let me enter th epassword for the wifi. I've reset my wifi, attempted to reinstall the software on my computer, and reset factory settings on the printer.

For the records, we investigated for a customer the very same problem.

It turned out that 802.11r amendment makes Canon wireless detection go crazy and see WPA2 network as unencrypted.

Turning off 802.11r on Wi-Fi properties allows the printer to see the correctg encryption and connect.

After succesfull connection, by the way, you can even turn 802.11r back on if needed.

HTH, HAND.

My experience with this problem on a TS5150:

The problem is IEE 802.11r [LINK REMOVED] which basically allows you to connect and re-connect to your wi-fi more smoothly when you wander round your house or offices with your phone or laptop.

Canon (it seems) don't support this standard - even though it's been around since 2008. Once I figured out how to turn 802.11r off on my wi-fi network, my printer sprung into action and prompted my for my wi-fi password and then connected - just like any other wi-fi enabled device might. I sahll have to live with reduced connectivity on all my other devices in order to make my Canon printer work.

It's difficult for me to offer any general  advice on turning 802.11r (AKA "fast roaming") off because there are lots of different types of routers and distribution hubs, but if Canon aren't going to fix this problem on their printers, it might be a good ide for them to draw up sets of instructions for a range of typical wi-fi set ups and publish these on their website and make their support staff aware of the issue.

The other workaround is, of course, a USB lead and printer sharing - though printer sharing is a whole other can of worms :-).

Hi,

as a workaround: you can turn 802.11r off, connect the Canon printer, and turn it back on. Connection remains stable this way.

Thanks for the tip. I'll probably try that but I'm slighlty reluctant as I got into the situation where the printer was not connecting at all because I was trying to fix the fact that my PC - though connected to my printer  - kept claiming the printer was "off line". A reboot usually fixed this problem. But I've not had a recurrence of this problem sinces I turned off 802.11r off, reset my printer, and reconnected my printer.
But I suppose the wosrt that can happen is that I have to go through this all again 🙂

Well my message about 802.11r trick was published on sep 09, 2020.

Since then, the affected printer has been connected with no issues at all to the network with 802.11r immedieately re-activated , so I suppose you can feel safe. 🙂

Made an account just to comment on this.

This is the only thing that solved my issue. Like some others, i could not find the fast roaming options (802.11r) in my router settings. But changing the security from `WPA3` to `WPA2` got the printer to connect to the wifi.

And afterwards, i changed the security settings back and it still stayed connected.

So thank you very much for this!

This sounds like the old 802.11r problem. See my posts https://community.usa.canon.com/t5/user/viewprofilepage/user- or mrwolf's id/190018 or https://community.usa.canon.com/t5/user/viewprofilepage/user-id/149756 

If so, you need to switch off 802.11r (AKA "fast roaming") on your router or "mesh" hubs - how to do this will be specific to whatever hardware you are using.

Using a service where I can not turn off the roaming feature 802.11r. Any other options besides USB?

Buy a cheap wifi repeater, add repeater to your network then add printer to repeater. Or by another printer.

Bought wifi repeater, added repeater to my network, attempted to add printer to repeater. Did ask for password, but did not connect. Tried several times. I've only had this printer for a year. Canon, anything?
