Why Your MT7621AT Can't Handle Multiple Devices Simultaneously: Causes and Solutions

The MT7621AT is a popular router chipset commonly used in various networking devices like routers and access points. However, one common issue users face is the inability of the device to handle multiple devices simultaneously, especially when many devices are connected to the network. This can lead to slow speeds, dropped connections, or even complete disconnection. In this analysis, we’ll break down why this happens and how to resolve it.

1. Cause of the Problem: Limited Processing Power

The MT7621AT chipset is a relatively mid-range processor designed for small-to-medium home and office routers. It comes with a dual-core CPU, but its processing power can be overwhelmed when there are too many devices connected to the network. Each connected device consumes a portion of the available bandwidth and processing power.

Why this matters:

When multiple devices are connected, each one needs to be processed and managed individually. If the router’s CPU is not powerful enough to handle these requests, the performance starts to degrade. For example, tasks like routing, encryption (for Wi-Fi security), and traffic Management can put a strain on the processor when dealing with a large number of simultaneous connections.

2. Cause of the Problem: Insufficient RAM and Bandwidth Allocation

The MT7621AT is equipped with a limited amount of RAM. This can lead to issues when many devices are connected, as each device requires some of the router’s memory to store data packets, routing information, and other network tasks.

Why this matters:

Insufficient RAM can cause the router to slow down as it struggles to allocate memory for each connected device. Also, bandwidth allocation may be poorly managed. Without Quality of Service (QoS) or a good traffic management system, certain devices may hog bandwidth, leading to lag and instability for others.

3. Cause of the Problem: Wi-Fi Interference and Range Limitations

Wi-Fi interference from nearby networks and physical barriers (walls, floors, etc.) can also impact how well the MT7621AT performs with multiple devices. If many devices are connected over Wi-Fi, the limited bandwidth and interference can lead to poor performance.

Why this matters:

Wi-Fi networks have limited frequencies and channels. In crowded areas with many nearby networks, this can cause interference, further slowing down the router's performance when handling multiple devices. Additionally, the MT7621AT’s wireless range might not be strong enough in large areas or multi-floor buildings, which can affect performance as devices are further away from the router.

4. Cause of the Problem: Firmware and Software Limitations

Outdated or poorly optimized firmware can hinder the MT7621AT’s ability to manage multiple devices efficiently. Many router chipsets, including the MT7621AT, rely on software optimizations and updates to handle more traffic or connected devices.

Why this matters:

An outdated firmware version may not take advantage of the chipset’s full potential and may struggle to allocate resources to multiple devices. In some cases, the router’s software may not be optimized for managing high traffic, leading to bottlenecks.

Solutions: How to Fix the MT7621AT’s Performance Issues

1. Reduce the Number of Devices on the Network

If you have too many devices connected, start by limiting the number of simultaneous connections. Consider disconnecting devices that are not in use and connect only essential devices to the network.

Step-by-step:

Check your device list in the router’s management interface . Disconnect any devices that you don’t need online at the moment. 2. Prioritize Traffic Using Quality of Service (QoS)

If your router supports it, use QoS settings to prioritize important devices or applications. This ensures that high-priority traffic (like video calls or gaming) gets more bandwidth while background tasks (like downloading) get less.

Step-by-step:

Log in to the router’s interface. Look for QoS or Traffic Management settings in the settings menu. Set up priority for critical devices or applications. Ensure non-essential traffic is limited. 3. Update Firmware

Keeping your router’s firmware up to date can solve bugs, improve performance, and offer better management of multiple devices.

Step-by-step:

Log into the router’s web interface. Check for firmware updates in the settings or system section. Download and install the latest firmware available for your router. Restart the router after the update is complete. 4. Change Wi-Fi Channels

Switching to a less crowded Wi-Fi channel can reduce interference and improve performance, especially in areas with many nearby networks.

Step-by-step:

Log into your router’s management interface. Go to the Wireless Settings section. Choose a less congested Wi-Fi channel (use a Wi-Fi analyzer app to find the best one). Apply the changes and restart your router. 5. Upgrade Your Router

If you find that the MT7621AT chipset is still unable to handle your needs even after optimizations, consider upgrading to a more powerful router. Routers with higher processing power, more RAM, and better Wi-Fi standards (such as Wi-Fi 6) are built to handle more devices simultaneously.

Step-by-step:

Research routers with a higher processing power and more RAM. Choose a router that supports Wi-Fi 6 for better performance and coverage. Set up the new router and transfer your settings.

Conclusion

The MT7621AT can struggle with multiple devices due to its limited processing power, memory, Wi-Fi interference, and firmware issues. By reducing the number of connected devices, prioritizing traffic, updating the firmware, and managing your Wi-Fi channels, you can significantly improve performance. However, if these steps do not resolve the issue, upgrading to a more powerful router may be the most effective solution.
