  • Updated 11 months ago
I am novice about the networks in general but have a good overall understanding. I am helping a small office to manage their network. We currently have 4 ap 121s with average 60 wireless devices per day. entire office uses business dropbox for data storage - no vpn, no bonjour gateway. we are experiencing some slowness which is given but I want to help them optimize the network. they were initially on both 2.4ghz & 5ghz. I have slowly closed own 2.4ghz. now i want to understand the different optimal settings in radio profiles to serve them better. Thank you.

When configuring your radio settings you always look at your clients first.  Laptops, for example, behave differently to smart phones.  

The next thing to look at is the applications you expect to carry.  If you are going to carry voice or video you need QoS enabled and load balancing disabled.

Which clients and applications are you expecting on your network?  I suspect general office applications like Internet, Microsoft applications, etc.

For an office based 802.11a/n/ac radio profile I would use:

Channel and Power
Use all the defaults with the exception of:
  • Max Transmit Power - 17 dBm
  • Channel Width - 40 MHz
Radio Settings
  • Beacon Period - 100 TUs
  • Enable Short Guard Interval - Enabled
  • Enable Aggregate MAC Protocol Data Units - Enabled
  • Enable the Detection of Spoofed BSSIDs - Disabled
  • Enable Frame Burst (Applies only to 802.11ac platforms except the AP370 and AP390) - Disabled
  • Enable Transmit Beamforming (Applies only to 802.11ac platforms) - Enabled
  • Enable MU-MIMO (AP250/AP245X/AP550) - Disabled
WMM QoS
Use the defaults

Antenna/Transmit and Receive Chain Settings
Use the defaults

Interference
  • Enable Interference Reporting - Your preference
Backhaul Failover
  • Enable Backhaul Failover - Enable

Optimizing Management Traffic Settings
  • Enable client load balancing among neighbouring hive members - Enable for data and disable for voice
  • Load Balancing Mode - Airtime-based (if client load balancing is enabled)
  • Weak SNR Probe Response Suppression - Disabled
  • Safety Network Check - Enabled
High-density WLAN Settings
Disable all options

Client Selection
  • Max Clients - 50
SLA Settings
  • Normal-density Network
WIPS server settings
Use the defaults

Sensor mode scan settings
Use the defaults
