Brother Printer Not Keeping Wi-Fi Connection

mac os tahoe 26.2 MacBook Pro (M4 Max) not keeping wifi connection with brother printer (DCP-L2640DW). i've tried turning off/on the printer. i've tried turning off both the MacBook Pro & the brother printer. I've pulled out plugs, waited 30 seconds and plugged back in, I checked Network settings on the printer, yes it was connected to my wifi network.I've done searches on Google but finding little on the subject. Anyone having or had a similar experience after updating to 26.2?

Any assistance would be greatly appreciated!

Thank you den.thed. It was the second point in your post, the printer was not keeping the connection with the Wi-Fi. I continued to research while waiting for a reply and found another post that sounded very similar to mine from CT. Just to be clear, I have a MacBook Pro (M4 Max and I've running macOS Tahoe 26.2). I found the following post on Brother support https://support.brother.com/g/b/faqend.aspx?c=us&lang=en&prod=dcpl2640dw_us_as&ftype3=2039&faqid=faq00100426_015 which I shortened to the following instructions:
