Optimizing wireless performance on 2.4 GHz

Often the wrong settings can lead to bad performance. Below some tips on how to optimize performance with basic settings.

• Suggestion 1:
  • Configure DCS of channel selection. 
    Dynamic Channel Selection (DCS) allows a Wireless AP to monitor traffic and noise levels on the channel on which the AP is currently operating.
  • When DCS is enabled in active mode and traffic or noise levels exceed the configured DCS thresholds, an alarm is triggered and an information log is generated. In addition, the AP ceases operating on the current channel and ACS is employed to select an alternate channel for the AP to operate on. DCS does not trigger channel changes on neighboring APs.
• Suggestion 2:
  • Separate the managed VLAN and SSID VLAN.
    This will avoid the data-packets transmission from the broadcast-packet interference. A large subnet increases broadcast and multicast traffics, which also raises the number of packet collisions and reduces the airtime fairness rate to slow down the network.
• Suggestion 3:
  • Configure the channel width. 
    On 2,4 GHz set the channel width to 20 MHz on 2.4 GHz. There are more non-over lapping channels available when using the channel width 20 MHz.
    
    
• Suggestion 4:
  • Adjust the multicast rate from 5.5 Mbps to 12 Mbps on the device
    ( If the AP has enough wireless coverage and signal) Essentially, the multicast rate is the minimum speed that a wireless device must be able to communicate in order to connect to the router. So, the lower the multicast rate, the further away, or more accurately, the weaker the wireless signal, are allowed to connect. Therefore, turning up your multicast rate will decrease the range of your wireless network. If you are experiencing your wireless devices constantly losing their wireless connections, and then restoring those connections automagically seconds later; check this setting. It’s probably too high.

Go to Configuration > Object > AP profile > Radio. Edit the radio profile of 2.4 GHz in Show Advanced Settings: Multicast Settings.
