why wont my iMac connect to my printer via my own wifi even though on different wifi speeds (2.4gHz vs 5gHz)?
How do I overcome connection failure between my iMac and Epson XP printer which are on same home wifi network (yup, checked both logged on properly, etc) but former is on 5GHz and latter is on 2.4GHz? Surely, shouldn't make any difference....?
Only a very recent problem, perhaps after latest macOS Big Sur update - suddenly stopped talking to one another wirelessly.
Failing that, how do I get a physical connection going?
iMac about 14 months old, printer only about 18 months old.
iMac, macOS 10.12
