Recently upgraded to from Performance Tier to Blast Pro looking for big performances enhancements. Well ethernet wise it runs fine I’m getting 250+ mbps. But Wifi is not so hot. Only getting about 60mbps on 2.4GHz and only 80mbps on 5GHz. The modem/router is an Arris SURFboard SGB6900-AC which is Arris’s most powerful router with download speeds up to 686 mbps and Wifi speeds up to 1900 mbps. So I am curious as to what may be causing the wifi to run so far behind?
