How to Prioritize Specific Devices on Your Router: MAC-Based Bandwidth Control and Device Priority Settings for ASUS, TP-Link, and Eero

Most households run 20 or more devices on a single router. When your work laptop competes with a gaming console, several streaming sticks, and a cloud backup client, the router treats every packet the same — which means the devices that matter most often lose. Quality of Service (QoS) and device prioritization settings let you tell your router which devices get first access to bandwidth during congestion, so your video call doesn’t freeze because someone started a 4K stream. Run a speed test first to know your actual speeds, then follow the steps below for your router platform.

What Device Prioritization Actually Does

QoS is the umbrella feature; device prioritization is one way to apply it. When you mark a device as high priority, the router’s traffic scheduler queues that device’s packets ahead of others during congestion. In practice, this means the device gets first access to available bandwidth when the connection is under load — not a dedicated slice of speed, but first place in line when capacity is limited.

There are two related controls worth understanding:

• Traffic priority: Elevates a device’s packets in the queue so it gets served before lower-priority devices. The best approach for gaming consoles, work laptops, and video conferencing equipment.
• Bandwidth throttling: Caps the maximum speed a specific device can use, preventing one device from consuming your entire connection. Useful for IoT sensors, guest devices, or automated backups.

Some routers support both independently. All three platforms below support at least one approach, and using a combination — elevating critical devices while throttling background devices — gives the best result.

ASUS Routers: Adaptive QoS

ASUS uses a system called Adaptive QoS, available on most current AiMesh, RT-AX, and RT-BE series routers. The interface lives at router.asus.com or 192.168.1.1.

Enabling Adaptive QoS on ASUS

1. Log in to the ASUS router admin panel and click Adaptive QoS in the left sidebar.
2. Toggle QoS to On.
3. Enter your connection’s upload and download speeds at about 85–90% of your tested maximum — this headroom prevents the QoS engine from over-saturating the WAN link and causing the prioritization to backfire.
4. Switch the mode to User-defined to access per-device controls.

Setting Per-Device Priority on ASUS

Under the User-defined tab, connected devices appear by hostname and MAC address. Click a device to assign a priority tier: Highest, High, Normal, Low, or Lowest. Devices at a higher tier have their traffic queued ahead of lower-tier devices during congestion. Set gaming consoles, work laptops, and video conferencing equipment to Highest. Smart home sensors, security cameras, and background backup clients work well at Low or Lowest — they’re not latency-sensitive and use relatively little bandwidth. For a deeper look at how ASUS handles traffic shaping, see our QoS settings guide.

TP-Link Archer Routers: HomeCare QoS

TP-Link’s WiFi 6 and WiFi 7 Archer models use HomeCare-based QoS accessible at tplinkwifi.net. Older models (Archer A6, C7, A7) use a simpler per-device priority toggle in the standard web interface.

Enabling QoS on TP-Link Archer (WiFi 6 and WiFi 7 Models)

1. Log in at tplinkwifi.net and navigate to Advanced → HomeCare → QoS.
2. Enable QoS and confirm the bandwidth values using your speed test results.
3. Switch to the By Device tab.

Setting Device Priority on TP-Link

Under By Device, connected devices appear by hostname and MAC address. Toggle the priority switch next to any device to elevate it. You can also set a timing duration — how long the priority boost stays active — which is useful for temporarily elevating a device during a gaming session or video call without permanently altering your network configuration.

On older Archer models (C7, A7, A6 V2), QoS lives under Advanced → QoS → Settings. Enable QoS, enter your bandwidth values, then use the Device Priority list to add devices by MAC address and drag them into priority order from highest to lowest.

Amazon Eero: Device Priority via the App

Eero manages all settings through the Eero app — there is no traditional web admin panel. Device prioritization is available on Eero 6+, Pro 6, and all Eero WiFi 7 models. Some advanced controls require an active Eero Plus subscription.

Setting Priority on Eero

1. Open the Eero app and tap Devices.
2. Select the device you want to prioritize.
3. Tap Device Priority and select High Priority.
4. Apply the change. The setting takes effect immediately without a router reboot.

Eero Plus subscribers can also set per-device bandwidth limits from the same device detail screen. If you need to cap a shared guest device or a bandwidth-hungry media server, select the device and enter an upload/download limit under the Advanced settings.

MAC-Based Priority vs. IP-Based Rules: Which to Use?

All three platforms identify devices by MAC address internally, even when the interface shows a hostname or device name. This is important for one key reason: a device’s IP address can change after a router reboot if it uses DHCP, but its MAC address never changes. If you configure QoS rules based on IP addresses and the device gets a new address, the rule stops applying.

The fix is a static DHCP reservation: assign a permanent IP address to the device’s MAC address in your router, then use that IP in any QoS or firewall rules. On ASUS, this is under LAN → DHCP Server → Manually Assigned IP. On TP-Link, it’s under Advanced → Network → DHCP Server → Address Reservation. On Eero, tap the device in the app and enable Reserve IP. With a reservation in place, the device always gets the same address and your priority rules remain stable across reboots.

When to Use Priority vs. When to Use Limits

Use QoS priority for devices that need to win traffic disputes: gaming consoles, work-from-home laptops, video call devices, and NAS units serving local media. Priority doesn’t restrict other devices; it just ensures the high-priority device gets served first when bandwidth is contested.

Use bandwidth limits for devices that could consume too much: automated cloud backup clients, guest network devices, IoT cameras, and smart TVs running background updates. Capping these devices prevents them from silently saturating your connection during work hours or gaming sessions.
