What is MLO in Wi-Fi 7 and Should You Enable It?
With the rollout of the Wi-Fi 7 standard, manufacturers have made significant promises to consumers, with Multi-Link Operation (MLO) standing out as the most prominent. This technology is a key feature of Wi-Fi 7, theoretically designed to drastically improve internet speeds and connection stability. In practice, however, the situation is far more complex, and current reality often falls short of these promises.
How does MLO work?
Simply put, MLO allows a router to connect to multiple frequency bands (2.4GHz, 5GHz, and 6GHz) simultaneously, distributing internet traffic between them. This technology is somewhat based on the older "band steering" principle, which enables a router to automatically switch to the clearest and fastest frequency. However, the older method was often unstable, causing connection drops during the switch. Ideally, MLO aims to solve this by utilizing several channels at once.
Reality and limitations
The issue is that there are two distinct types of MLO. The first, Simultaneous Transit and Receive (STR), involves multiple radio modules working at the same time. The second, Enhanced Multi-Link Single Radio (EMLSR), uses only a single radio module that monitors all bands and switches as needed. As of February 2026, the vast majority of Wi-Fi 7 routers on the market have failed to support full-fledged, multi-radio MLO.
Furthermore, there are compatibility issues. To utilize the full potential of Wi-Fi 7, both your router and your device—such as a smartphone, laptop, or network card—must support the new standard. If your network includes older Wi-Fi 6 devices, they will not benefit from MLO. In some cases, enabling MLO on incompatible devices can actually lead to network instability and connection drops.
Should you enable MLO?
There is no single answer to this question. If your home uses a mix of devices and you do not have a system that fully supports Wi-Fi 7, it is better to keep MLO disabled for now. However, if you have fully transitioned to Wi-Fi 7 and use modern hardware, you can experiment to see if your network performance improves with the feature enabled.
Depending on your router model, MLO settings can be found in different places. For instance, UniFi and eero devices have this feature in their mobile apps, while Linksys requires access via the web interface. In most cases, the feature is disabled by default, though it may be active on some ASUS models. We recommend checking your router settings and testing which mode provides the best results in your specific environment.
