   Android debugging tools to find noise so

   I'm relatively new to wireless networking & ask you for debug advice.   
   Everything is working but there are errors I'm trying to figure out.   
   https://i.postimg.cc/FR3X1FC5/settings.jpg   
      
   Where that "wireless bridge client repeater" is bridged 1:1 to an   
   access point which happens to be on the non-overlapping channel 11.   
      
   The debug took I'm using on Android to find the noise sources is this.   
   https://play.google.com/store/apps/details?id=com.ubnt.usurvey   
      
   But of course, that only records Wi-Fi sources, not all nearby radios.

   While that only shows wi-fi interference sources, there are   
   no baby monitors nearby that I know of. No microwave in use.   
   No airport nearby. No doorbell cameras. Nothing that I know of.   
      
   Even the phone, connected to that same channel 11 access point   
   shows a steady downarrow of 390Mbps but the uparrow flips every   
   few seconds between 433Mbps and 6Mbps (consistently the same numbers).

   While I'm not at all sure what that even means for the uparrow to   
   be flipping between over 400Mbps and less than 10 Mbps, below are   
   the basic wireless settings of the bridge connected to the desktop.   
   1. Desktop PC 1 floor from the main router has no Wi-Fi. Only Ethernet.   
   2. So I plugged an old Netgear WNR834Bv2 into that Ethernet RJ45.   
   3. And I installed DD-WRT onto that Netgear WNR834Bv2 & set it up as   
       Setup | Advanced Routing | Operating Mode = Router   
       Setup | Basic Setup | WAN Connection Type = Disabled   
       Wireless | Basic Settings | Radio Mode = Repeater Bridge   
       Wireless | Basic Settings | Network Configuration = Bridged   
      
   How do I debug the high transmission error rate?   
    Status | Wireless | Wireless Packet Info | Received (RX) = 100%   
    Status | Wireless | Wireless Packet Info | Transmitted (TX) = 14%   
      
   And how do I investigate the source of this continued interference?   
    Status | Wireless | Access Points & Clients | Signal = -38 dBm   
    Status | Wireless | Access Points & Clients | Noise = -81 dBm   
    Status | Wireless | Access Points & Clients | SNR = 43   
      
   There are a few questions related to how do I debug?   
   a. What Android tool will find noise sources _outside_ Wi-Fi channels?   
   b. How do I test for where all that noise is coming from?   
   c. Why am I receiving all but losing almost all my bridge packets?
