   As I understand it, the Pringles "cantenna" was intended to be maximally   
   directional. If I understand my problem correctly the need is to "shadow"   
   my access point from the neighbors more than to direct transmit power   
   to my clients (signal level at the client location is ~90% per wavemon,   
   80% gave good connectivity until recently).   
      
   There seem to be a few complaints about wifi behavior on the Forums,   
   since my problems appeared out of the blue after an upgrade it's possible   
   that software is involved also.   
      
   Something very similar happened after a bookworm upgrade a few months ago.   
   After some hair-pulling and a few more upgrades it simply went away.   
      
   As an aside, now wavemon seems to crash on its own, reporting:   
      
   │Waiting for scan data ...free(): double free detected in tcache   
   2 │   
   │ Aborted   
      
   That seems clearly to be a software issue, though whether in wavemon or   
   somewhere else isn't clear to me.   
      
   Thanks for writing,
