I'm sure this has been addressed earlier, but I can't seem to find it.
I have a friend with a Pixma MX922 which I understand only connects at 2.4g. She cannot print or scan when she is connected to her router at 5g. She keeps having to switch her laptop down to 2.4 whenever she wants to do that. Her laptop is a Dell running Windows 10, but her husband has a Macbook and has no problems with this.
Any ideas/suggestions, etc? If any specific information is needed, please let me know and I'll be glad to supply it. Thank you in advance.
