title: Wifi diagnostic tool
body: <p>I am working on a room which contains 6 wifi IP cameras. There are also the same wifi IP cameras in other close rooms. This cameras have their own wifi access point. I can't manage anything on this wifi network.</p>
  
  <p>I have a raspberry Model 3 in this room. I tried to set up a wifi access point on this raspberry.</p>
  
  <p>I can't connect to this access point, but if in unplug everything and go to try far away from this rooms, everything works great.</p>
  
  <p>So i am wondering if the raspberry is not disturbed by this big wifi traffic.</p>
  
  <p>What should i do ?</p>
  
  <p>Here is an extract of my /etc/hostapd/hostapd.conf</p>
  
  <p>Do you see something i can change in order to make it work ?</p>
  
  <pre><code>interface=wlan0
  driver=nl80211
  ssid=XXXX
  hw_mode=g
  channel=6
  ieee80211n=1
  wmm_enabled=1
  ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]
  macaddr_acl=0
  auth_algs=1
  ignore_broadcast_ssid=0
  wpa=2
  wpa_key_mgmt=WPA-PSK
  wpa_passphrase=XXXXXXX
  rsn_pairwise=CCMP 
  </code></pre>
  
  <p>Thanks</p>
