🔍 Overview

In office networks or even advanced home networks with many connected devices, a few clients consuming excessive bandwidth is a very common issue. This often leads to slow, unstable connections and directly impacts critical services such as VoIP, IP cameras, ERP systems, VPN, or online meetings.

With UniFi Controller, you can easily set bandwidth limits for each individual client in a clean, centralized, and efficient way. In this guide, TSF will walk you through how to configure per-client bandwidth limits on UniFi WiFi, helping you keep your network stable and fair for all users.

🎯 Why Limit Bandwidth on UniFi?

✅ Prevent a single device from saturating the entire network
✅ Ensure stable performance for all connected users
✅ Prioritize bandwidth for critical services and devices
✅ Manage WiFi networks in a professional, enterprise-ready way

🧰 Prerequisites

🔹 UniFi Controller (Cloud Key / UniFi OS / VM / Docker)
🔹 UniFi Access Point already adopted
🔹 Client devices currently connected to WiFi
🔹 Admin-level access to UniFi Controller

⚙️ How It Works (Quick Explanation)

UniFi applies per-client bandwidth limits using User Groups. You first create a User Group with specific download and upload limits, then assign that group to selected clients.

📌 This approach is flexible, scalable, and does not affect the entire SSID or network.

🛠️ Step-by-Step: Set Bandwidth Limit for Each Client

🔹 Step 1: Access UniFi Controller

➡️ Log in to UniFi Controller
➡️ Go to Settings → Profiles → User Groups

🔹 Step 2: Create a Bandwidth-Limited User Group

➕ Click Create New Group

Example configuration:

• Name: Limit_5Mbps

• Download Bandwidth: 5 Mbps

• Upload Bandwidth: 5 Mbps

💡 You can create multiple groups such as:

• Limit_2Mbps (Guest devices)

• Limit_10Mbps (Staff devices)

• Unlimited (Admin / IT)

➡️ Click Save to apply

🔹 Step 3: Assign the Bandwidth Limit to a Client

➡️ Go to Clients
➡️ Select the target device
➡️ Open Settings / Configuration
➡️ Choose the appropriate User Group (e.g. Limit_5Mbps)

✅ The bandwidth limit is applied immediately, no AP restart required

📊 Monitoring and Verification

🔍 From the UniFi Controller, you can monitor:

• Real-time download and upload usage

• Client connection status

• Bandwidth consumption per device

📌 UniFi provides detailed visibility without the complexity of traditional QoS configurations.

⚠️ Important Notes

⚠️ Bandwidth limits apply per client, not per SSID
⚠️ Avoid setting very low limits for devices using VPN or cloud services
⚠️ For larger deployments, combine VLANs + SSIDs + User Groups for optimal control

🧠 Conclusion

Setting bandwidth limits per client on UniFi WiFi is a powerful yet simple feature. With just a few configuration steps, you can stabilize your entire network, prevent bandwidth abuse, and significantly improve user experience.

If you are deploying UniFi for an office, café, factory, or enterprise WiFi system, this is a configuration you should implement from day one.
