    How reliable is the broadband checker? 9th Jul 18 at 2:45 PM
    I just had my bt superfast essential bb activated. The bt checker records a speed of 38 mbs compared to 2 mbs I am used. The broadband checker from the internet records 17 mbs. So this cannot be right guaranteed speed of 35 mbs with bt . I will go with the bt checker for accuracy but do not understand why there is such a big difference between the two! Thanks

    There are reported issues with the BT Speed tester at http://speedtest.btwholesale.com/ where it is misreporting speeds when used with Chrome or Firefox.
    My 76Mbps line reported at 360Mbps in one such test using Chrome. BTW are aware of the issues and are very slowly working on a replacement.
    I now use the Edge browser just for the speed test. Others have reported that Safari and Opera also produce reliable results.
    I would also compare your results against another reliable tester like the ThinkBroadBand at https://labs.thinkbroadband.com/speedtest/

    Firstly, are you checking with a hard wired ethernet connection? If not, then wireless interference can easily knock your speed down.

    Try putting your phone number into this

    https://www.dslchecker.bt.com/

    This will tell you the estimated VDSL speed for your line.

    If the speed that you are getting is way below this, then there could be a problem with the line. You may need to check with BT that your profile has been set up correctly.

    Also, with a new connection, it can take a few days for the DLM (Dynamic Line Management) to settle down to a stable speed.

    I would agree that you should junk the BT checker, it's very variable. I've always used www.speedtest.net as you can join for free and it'll keep a history for you.

    As said above you need to check with a wired connection and of course nothing else should be using your connection at the time.
