Out of interest did you remedy?
I understand that Canon is recommending splitting the SSID for the 2.4GHz and 5GHz bands, but I’m not convinced that’s the real issue here... It seems an odd one to me:
I assume the Canon printer only supports 2.4GHz Wi-Fi?
This means that it iterally cannot connect to, interact with, or become aware of a network on the 5GHz band by itself.
A device that only is able to scan 2.4GHz does not even know the 5GHz band or any networks on that band exist. Hence, it is hard to see how having the same name for both 2.4GHz and 5GHz would confuse the printer. It should just connect to the 2.4GHz network, as this is the only network it can see, and off it goes, educating all on the imporance of genuine ink cartridges around the clock.
The real issue is likely something else, like:
1. Printer may not support modern security standards of encryption. WPA3 is the latest standard to protect the WiFi password from attackers. It was released in 2018, yet many devices have not been updated by their retrospective vendors 6 years later.
It used to be ISPs allowed us to downgrade our networks to what is frankly insecure. Then Apple began placing "WEAK SECURITY" warnings below the network names in the wifi connections list, meaning ISP's had their name / brand associated with "WEAK SECURITY" & screenshots of this all over social media.
Some ISP's e.g. TalkTalk actually had 4 models configured, for all customers, in a mode that triggered "WEAK SECURITY" popups for iphone uses on the day it went live.
Nowadays, ISP's just say no.
2. It could also be WiFI standards, "AX standard"(AKA WiFi 6) applies to the 2.4GHz band also.
This was released 2019. If the device is 5 years behind the curve in its knowledge, and has no awareness of WiFi 6 being a thing, it will not even recognise it as a network. It will not show in the list at all. It will show other networks (if they are WiFi 5 or older), but it wont show your WiFi 6 network.
So, this really feels like a bandaid or an excuse. What they probably mean is that they have not invested in necessary security updates for years on years, and now they're not able to see a secure network (despite having 5 / 6 years to get there). They're acting like it came out last week 🙂
You could investigate 1. Downgrading to WPA2. I am unsure if possible *assume it is possible*. This may weaken security to a degree. Realistically most people are not aware of how to compromise a network, but still - it's always a bigger risk to lower security.
2. Downgrade the network from WiFi 6 (AX) standard to WiFi 5 or older (prob shows up as AC mode). E.g. Instead of selecting AX/AC/N/G/B mode select something like AC/N/G/B (losing the AX means we lose the latest and greatest standard). This means we set the network to the pefromance of an older and less speedy standard.
3. If using a Canon setup programme, disable the firewall before you run the programme. FW's and printer setup utilities = BAD.
4. I beleive Sky facilitate disabling 5GHz via MySky app, it reduces network performance and settings, meaning it cannot be enabled again via app easily. However pin reset would take you back to factory settings (and hopefully once printers connected once it'll stay connected).
