slow wifi connectivity
We recently upgraded our internet connection. My son's gaming PC (built within the last 6 months) is getting download speeds of 903 mbps. He is connected via ethernet cable.
My iMac (21.5" late 2013) is getting 29.3 mbps. Processor is a 2.7 GHz Quad-Core Intel Core i5. I'm running macOS Catalina version 10.15.7
Is my iMac just too old to accommodate the new internet connection?
Do I need to restore the previous OS?
Or do I just need to bite the bullet and buy a new computer or are there upgrades I can have done on this one?
