Checking Internet speed?

How do I appropriately test my internet speed? And what are realistic expectations?

The wireless icon at the bottom of my Lenova laptop indicates 130Mbps. When I run an actual ping speed test at, I get a download speed of about 20Mbps and an upload speed of about half that. I'm paying for 'Premier' Cox service that advertises speeds up to 150Mbps.

    Realistic expectations with Premier service, that depends on how you are connected .....

    Wired Ethernet using cat-5e or cat-6 cable and gigabit ports, you should get the full 150+ Mbps
    Wired Ethernet using 100Mbps ports, you will be limited to <100Mbps.
    WiFi using 5GHz ac wireless you can get the full 150+ Mbps.
    WiFi using n wireless, realistically, 40 to 80 Mbps depending on distance, band, and interference.  Could even be less.
    WiFi using g wireless, about 20Mbps.

    What modem/router or gateway are you using?  Speedtest dot net is fine for testing.  True test of the cable connection is wired directly to the modem/gateway with gigabit ports.  You can also test using a link on Cox Internet Tools page.  Please post your setup and results if you want to debug.  Thanks
