Horrible signal to noise ratio

Attempted to move my router all around my apartment and unfortunately the speed got progressively worse as I tried. So I put it back to where it was before and unfortunately now the speed is much slower than it was before I moved it!

My signal to noise ratio on my primary signal is 0 dB!  Obviously you can't get any worse than 0 db for signal to noise ratio! I also noticed that my band on my primary signal has now changed to be B66, where this afternoon it was B2. I don't know if that change was what made things worse.

 

You had mentioned that I'm very close to the 5G. How were you able to determine that and is there anything I can do on my end besides moving my router? Does the secondary single even matter? The reason I'm asking is it seems I'm not even using the secondary signal despite it being there so is everything relying on the primary signal? It sure seems that way because I get the feeling the secondary single is not even being used. I wish there was someway I could get them to have the point at the secondary signal and make that the primary one.

Hola David,

Your SNR can certainly drop below 0 dB to negative values - it is not a linear thing with zero being no signal.  SNR is 10 times the log (base 10) of the ratio of powers of the signal to the noise in the receiver bandwidth.  So when they are equal, that ls 10 times the log of 1, which is 10 times zero, or zero.  When the noise exceeds the signal, you get negative values.  You can still get reception with negative values, but it's not a great place to be.
