Update - a day after completing the factory reset, I received an insight
informing me that the cable between the modem and router was
underperforming (I'm paraphrasing). I replaced the factory ethernet
cable and my speeds are back where they belong. ...
Completed the factory reset and still have slow wifi. Modem is pushing
320mbps but wifi is only putting out 90mbps. Any other suggestions? I'd
love to know what changed on Feb 19 to cause this.
Similar issue here - on Feb 18 I was pulling 320Mbps, on Feb 20 it
dropped to 90mbps. haven't been able to get to get those speeds back.
Tested modem and the modem is pushing 360mps.
