   From what I gather the 5.2 volt requirement applies to Pi5 with   
   internal WiFi. This is a Pi2B with no internal WiFi.   
      
   The dongle is on a powered hub (part of a Dell monitor with a built-in    
   hub). The hub is putting out 5.12 volts with the WiFi dongle active.    
   The WiFi dongle is on a short USB-A extension cable to allow positioning    
   for best reception, which varies wildly over a few inches.    
      
   There's a fairly clear correlation between WiFi signal quality declining   
   and the keyboar/trackpad becoming unresponsive. It tends to happen in the   
   evening and I'm guessing it's interference with neighbor's access points,   
   which are abundant.    
      
   It does appear that the firmware-realtek package can be upgraded, but trying   
   sudo apt upgrade realtek-firmware   
   reported that upgrade does not take arguments.    
      
   It appears that I need to use   
   sudo apt install --only-upgrade firmware-realtek   
   but I haven't tried it yet. Can anybody confirm this is the correct command?   
   I'd rather not alter anything else right now.   
      
   Thanks for writing!
