   Yes, it's a bit manic, but you can alter that in the options.

   It's neither of those.  In fact, I've just searched for it and can't   
   find it in the App Store any more, I don't know why not but perhaps the   
   original developer lost interest in updating it.  The only 'versions' of   
   it around now seem to be from unreliable sites which I wouldn't wish to   
   recommend because at least some of those 'versions' seem to be flagged   
   as potential malware.  I bought my first android smartphone in 2012 and   
   a year or two later found WiFi Analyzer (the one we're discussing, by   
   Kevin Yuan) in the App Store and installed it on that phone; AFAICR   
   without actually checking, my current phablet is about 5 or 6 years old,   
   and the app was still in the App Store when I was setting up that   
   tablet, or perhaps I just copied it from the phone; in neither of these   
   cases were there any problems from malware using the original app from   
   the App Store.  I suppose what has happened since is that malware   
   writers have hijacked a clean original version from when it was widely   
   available and adulterated it.   
      
   So if the one you are using is working satisfactorily, I wouldn't bother   
   about trying to find another.

   That at least is a significant improvement, but it's still not   
   symmetric, although it now may well be liveable with, only you can   
   decide that.  Also it does suggest that I was on the right track to   
   suggest a problem with the system rather than extraneous noise.  Did you   
   check whether you are using the latest version of DD-WRT for that device   
   as well as the latest firmware for the other parts of the system?  I   
   wonder is there's some intermittent hardware problem somewhere with   
   which the updated firmware is better at coping.
