I've done 4 speedtests. Supposed to have 200-250mbps. 3 times tested from my iPhone 7 and my download speed is 62-78. Another time from my windows laptop and it's 21!!! What's going on? I've reset the router twice. It's the one we rent from Comcast and it's fairly new. I'm going to try to test from a different location in the house to see if that makes any difference at all.
