Radio Profiles – Complete Configuration Guide
Overview
Radio Profiles help manage and optimize the wireless (RF) behavior of Access Points (APs). They control how Wi-Fi operates, including:
Channel selection
Signal strength (power)
Performance tuning
Client handling
To create a Radio Profile:
➡️ Go to:
Organization → Radio Profiles → + Add Radio Profile
Basic Configuration
🔹 APs / Networks
Choose where the profile applies:
Network Level → applies to all APs
AP (Device) Level (MAC address) → applies to a specific AP
Important:
If both are configured → AP-level profile takes priority
🔹 Name
Give a clear name (e.g., Office-5G-Profile)
🔹 Country
Defines:
Allowed channels
Power limits
Regulatory rules (DFS/non-DFS)
📶 2.4 GHz Radio Settings
🔹 Disabled
Select No → Enables the radio
Select Yes → Disables the radio
🔹 Country IE
Broadcasts country information to devices
Helps devices connect correctly
Recommended: Enable
🔹 Channel Bandwidth (MHz)
Option | Meaning |
20 MHz | Stable, less interference |
40 MHz | Faster, but needs clean environment |
Recommended:
Dense area → 20 MHz
Open/clean area → 40 MHz
🔹 Channel
Auto → AP selects best channel
Manual → You choose a fixed channel or channels list
Recommended: Auto
🔹 Valid Auto Channel
What it does:
Defines which channels AP is allowed to use in Auto mode
Let's you choose allowed channels
👉 AP will only pick from this list
🔹 Power (dBm)
Auto → Adjusts automatically
Manual → Fixed signal strength
👉 Higher power ≠ always better (can cause interference)
Recommended: Auto
🔹 Channel Utilization Measurement
Monitors how busy the channel is
Helps optimize performance
⚠️ Works only on supported hardware
Advanced Settings (2.4 GHz)
🔹 Maximum Clients
Limits how many devices can connect.
👉 Why:
Too many devices → slow network
Use in crowded environments
🔹 Multiple BSSID
Allows an Access Point (AP) to combine information for multiple wireless networks (SSIDs) into a single beacon frame, rather than broadcasting separate beacon frames for every individual network
🔹 Beacon Rate
What it is:
Signal sent by AP to announce Wi-Fi
👉 Think of it as: “Wi-Fi is here” signal
Impact:
Low rate → better coverage
High rate → better speed
Recommended: Default (None)
🔹 Beacon Interval
What it is:
How often beacon is sent (in ms)
Default: 100 ms
Impact:
Lower → faster detection, more overhead
Higher → less overhead, slower detection
Recommended: 100 ms
🔹 DTIM Period
What it is:
Controls when devices receive pending data
👉 Important for:
Notifications
Calls
Background apps
Impact:
Low (1–2) → faster delivery
High (3+) → better battery
Recommended: 1–3
🔹 Multicast Rate
Controls speed of broadcast traffic (video, streaming)
Important for:
IPTV
CCTV
Streaming
Recommended: Default
🔹 BSS Color
Used in newer Wi-Fi (Wi-Fi 6), Wi-Fi mechanism introduced in Wi-Fi 6 (802.11ax) that adds a numerical identifier (a "color" from 0 to 63) to wireless frames to help devices immediately distinguish between their own network and a neighboring network on the same channe
👉 Helps reduce interference between nearby networks
Recommended: Default
📡 5 GHz Radio Settings
🔹 Disabled
Select No → Enable radio
🔹 Country IE
✔ Recommended: Enable
🔹 Channel Bandwidth (MHz)
Option | Meaning |
20 MHz | Stable |
40 MHz | Balanced |
80 MHz | High performance |
✔ Recommended:
Office/Home → 80 MHz
Dense environment → 40 MHz
📊 Channel Availability Behavior
Bandwidth | Channels |
20 MHz | More channels |
40 MHz | Fewer |
80 MHz | Limited |
🔹 Channel
Auto → Best channel selected automatically
Manual → Fixed
✔ Recommended: Auto
🔹 Valid Auto Channel
Very Important Setting
Let's you choose allowed channels
Includes:
Non-DFS channels (36, 40, 44, etc.)
DFS channels (100, 120, 132, etc.)
👉 AP will select best channel from this list
🔹 Power (dBm)
✔ Recommended: Auto
🔹 Channel Utilization Measurement
Detects congestion
🔧 Advanced Settings (5 GHz)
(Same behavior as 2.4 GHz, but more impactful due to higher speeds)
🔹 Maximum Clients
Limit load per AP
🔹 Multiple BSSID
Use carefully
🔹 Beacon Rate
Keep default
🔹 Beacon Interval
✔ 100 ms
🔹 DTIM Period
✔ 1–3
🔹 Multicast Rate
Important for streaming
🔹 BSS Color
Useful in dense deployments
⚡ Advanced Radio Management
🔹 Client Steering
Moves devices between 2.4 GHz and 5 GHz automatically
🔹 Association Steering
Controls how clients connect, stickness session between client and AP
🔹 Automatic Channel Balancing
Distributes channels across APs
🔹 Probe SNR
Controls signal threshold for new connections
🔹 Roam SNR
Controls when devices roam between APs
🔹 Min Load (%)
Helps distribute users across APs
⚠️ Important Notes
Channel selection depends on:
Country
Channel width
DFS availability
DFS channels:
May delay connection (radar detection)
Provide less interference
Best Practices
✔ Use Auto channel + defined valid channel list
✔ Prefer 80 MHz (5 GHz) for performance
✔ Use 20/40 MHz in crowded areas
✔ Avoid too many SSIDs
✔ Keep most advanced settings at default
Summary
Radio Profiles control Wi-Fi behavior centrally
Proper configuration improves:
Speed
Stability
Coverage
Advanced settings should be used carefully
