Having problems with poor WI-FI connectivity, slow connection speeds, devices dropping off WI-FI?
By now, you have likely discovered that UniFi WI-FI isn’t quite a plug and play solution and it always requires optimizing controller settings to achieve best WI-FI experience.
Now, since every network is different and there are different use cases, density of clients, some settings may not be applicable to all.
Below are outlined general best practices to optimize performance on your Ubiquity WI-FI networks.
On WLANs greater than three WAPs, typically one should disable some of 2.4 GHz radios to reduce crosstalk/Co-Channel interference (CCI)
Always perform RF Environment scans when installing WAPs and set channels manually (never Auto)
For 2GHZ use channels: 1, 6, 11 on adjecent WAPs to eliminate overlap
For 5GHz use: 36, 40, 44, 48, 149, 153, 157, 161 – recommended to use 40MHz, if use 80MHz, available non-overlapping channels are: 36 and 149 or 48 and 161
Do not use DFS channels
Channel width: 20Mhz, 40mhz, 80mhz (more airtime, more noise, more interference), when using higher channel width, the number of available channels goes DOWN
Settings – services – Uplink connectivity monitor – Off
Automatic upgrade AP firmware – Off
Auto Optimize Network – Off
Wireless Networks – Fast Roaming – Off
Multicast and Broadcast Filtering – Off
High Performance Devices – Off
Power – Auto or Low
YMMV
802.11 Rate and Beacon Controls – 6mbps for 2GHz and 9-12Mbps for 5GHz
Disable CCK Rates (1/2/5/11 Mbps)
