Posted results from status you requested. Yes , when I bypass router I am getting 900 plus mbps so it appears I am getting my gig speeds from Xfinity. I then reconnected to router and tested different angles on my router antennas but best top speed was around 650 mbps. These tests were done sitting in front of modem and router. I then went to my living room where I use my iPhone and iPad . That is where I am only acheiving the average 250 or so mbps. I know walls and such cause distortion , but my Netgear modem and router make dels tout big whole house coverage . My home is only 2100 sq. Ft. I know moving the location of router/modem to my living room would help , but while sitting in front of them in current location , I could only achieve the 650 or so average , big drop off from the gig. Do you see anything abnormal or have any suggestions ?
Thanks !

Based on the areas in bold, I conclude you are testing over Wi-Fi.  If that is the case, you will not see Gbps throughput.  In fact, the 650 Mbps is outstanding.  For consistent results, make sure you are using the Ookla installable test application.  It is available in your play store.  Avoid web browsers and web sites for throughput testing.

For some background reading on Wi-Fi speeds, this is a great reference:
