Wi-Fi Signal Strength Checker

Your TV, router app or phone shows signal as dBm, a percentage or bars. Enter what you see and find out whether it is strong enough to stream without buffering.

-90 -30 dBm TV -60 dBm: Good Closer to zero is strongerlivenettv.mn
the closer the reading is to zero, the stronger the signal; below about -72 dBm, streams start to stutter.

What the numbers mean

dBmRatingFor streaming
-30 to -55Excellent4K with room to spare
-56 to -67Good4K and Full HD reliably
-68 to -72FairHD, with occasional buffering
-73 to -80WeakSD at best, frequent drops
below -80UnusableConnection keeps dropping

dBm is a negative number: -50 is stronger than -70. Percent and bars are converted to an approximate dBm, since every device scales them differently. On Fire TV, find the signal under Settings › Network, then press Play/Pause on your network for details. Our buffering guide covers router placement step by step.
