I have a fiber optic connection with a Huawei OptiXstar Wi-Fi 6 router, recently installed as an upgrade over the previous one (a FritzBox 7490).
My printer is a Canon i-Sensys LBP223DW which, until before this change, was always being recognised without any issue by all my (and my partner’s) devices.
The line is configured with a 2.4 and a 5 GHz networks. All devices (an iPhone 6S+ & an iPhone XS; an iPad Pro 9.7 (2015), an iPad Air 2020, and an iPad Pro 2018; a Mac mini 2018 and a MacBook Pro M3 Max) connect flawlessly to both networks.
IoT devices (we have very few, a dehumidifier, a vacuum cleaner, and the printer) require 2.4 GHz networks—no idea if this is due to their age or other choices.
My workflow was to go to print a document, tap on Select Printer, and it would be there in the list waiting for me. Today, I noticed this was no longer the case. I reset the printer and reconfigured it from scratch, adding it to the local 2.4 GHz network. The printer’s screen said connection was “Good”, and the name of the network was correct. Yet, the MBP M3 Max with macOS 15.1 would see it (as it was configured before in Sonoma) with a yellow light. It would not print. I removed it and tried to add it again. macOS would not see it as before.
From the printer screen, I browsed to find its IP address, then, on macOS, added the printer through the IP tab, which worked. My iPhone XS (iOS 18.1) and iPad Pro (iPadOS 18.1) would not see it. I restarted the printer, then those devices would see the printer.
My partner’s devices (iPhone on iOS 16.7, iPad Pro on iPadOS 16.7.10, iPad Air on iPadOS 17.6), though, would not find the printer unless they would switch their wifi connection to the 2.4 GHz as well, something that neither the Mac nor my other devices had to do.
I tried to restart the devices, to forget the networks and reconnect, nothing. If they are on the 5 GHz they would not find the printer.
Honestly, this looks like a stupid issue, but I have no idea how to work around it? Is it my new router doing something against specific devices which have an older internet protocol? Please notice that their connectivity is perfect though. Is it the printer?
What would you suggest me to do?
Thank you!
