Decoding MLO on Your Router: Should You Activate It?

Manufacturers of network devices have made numerous ambitious claims about Wi-Fi 7, particularly regarding Multi-Link Operation (MLO). This new feature is designed to enable routers to connect to multiple frequency bands at the same time, thereby distributing internet traffic across these bands. Theoretically, this should result in improved internet speeds and more reliable connections; however, in practice, MLO’s capabilities still have yet to be fully realized.

MLO can be seen as an advancement over band steering, which was previously used in older routers to automatically switch between different frequency bands for optimal connectivity. However, this switching mechanism can be imperfect, leading to slower speeds on congested bands or instability during transitions. Ideally, MLO addresses these issues by transmitting portions of data across all three bands simultaneously. Despite this promise, some obstacles currently limit the advantages users can experience.

The primary complication with MLO is that it actually encompasses two distinct implementations. The Simultaneous Transit and Receive mode illustrates MLO as often promoted, utilizing multiple radios in a router to connect to various bands at once. Conversely, the Enhanced Multi-Link Single Radio mode employs a single radio to continuously monitor all available bands, switching to the optimal option without causing interruptions typical of traditional band steering. Recent analyses have shown that, as of February 2026, no Wi-Fi 7 router has fully supported the complete multi-radio version of MLO.

While this still represents an improvement over older models, device compatibility poses further challenges. Since Wi-Fi 7 is a newer standard, users upgrading their existing networks might end up mixing new Wi-Fi 7 routers with older Wi-Fi 6 devices. However, only Wi-Fi 7 supports any variant of MLO, so devices linked to Wi-Fi 6 access points won’t reap any advantages. Additionally, not all devices are designed to utilize Wi-Fi 7’s benefits; if your smartphone, laptop, or network adapter is incompatible with Wi-Fi 7, enabling MLO may lead to network issues.

This uncertainty makes it difficult to provide a definitive recommendation on whether to enable MLO. If you’re planning to use a Wi-Fi 7 router as part of a mixed network or do not possess Wi-Fi 7 compatible devices (which applies to many users), it may be prudent to disable MLO at this time. However, if you are ready to fully commit to a Wi-Fi 7 environment and have a top-tier laptop to match, testing your network performance with MLO on and off may be worthwhile.

Activating or deactivating MLO will vary depending on the router model. For instance, UniFi and eero routers include MLO settings in their respective apps, while Linksys offers these options through its routers’ web interface. Typically, MLO is disabled by default due to potential incompatibility with older hardware; however, some ASUS routers may have MLO enabled out of the box. It is advisable to inspect these settings to ensure compatibility with your specific needs.
