stumped for an answer

I also have my router transmitting both 5GHz & 2.4GHz.
- My printer can only work with 2.4GHz.
- My computer can work with both. I have it set to prefer the 5GHz and to prevent AutoSwitch while it's on that network.
[5GHz is both faster and much less cluttered with stray signals from passing vehicles & my neighbours.]


I believe that my computer & router can be set up to allow connecting to both 5GHz & 2.4GHz at the same time, some sort of combined signal that contains both frequencies, with considerable speed advantage but I put that on one side to be investigated when I get around to it. And I seem to have mislaid my notes on the subject and cannot even remember what this mode is called.

Ok Denis well my printer can work on either frequency I was under the impression that all printers were stuck with the 2.4Ghz but Canon support replied to me on a query I had with the new printer and they stated the printer I had bought works on both 2.4Ghz & 5Ghz.
Now I think some of my problem with connecting to the printer is maybe in part that when I power on the laptop I never know which frequency the net connection will be in as it is nearly always different to the one I left it in when shutting down.
Whether this is due to the laptop hardware the router or the OS butting in I have no idea. The internal card a Realtek RTL8851BE WiFi 6 I have disabled because it was obviously not working as it should be and I am now using a TP-Link Archer T2U Plus AC600 High Gain Wireless Adapter which works fine so why the connection still flicks between those two frequencies I think has to be down to the laptop hardware or more so the operating system.
To be up front I just do not like this 25H2 version and problem there is I am stuck with it.
