Wi-Fi 7’s Biggest Selling Point Is Missing From Every Router
Hardware tests show every Wi-Fi 7 router sold today relies on a single-radio fallback instead of the simultaneous transmission buyers paid for.
Consumers paying premium prices for Wi-Fi 7 routers are buying hardware that cannot deliver the standard’s flagship feature. According to a February 2026 report by hardware testing site Rtings, not a single Wi-Fi 7 router currently on the market supports Simultaneous Transmit and Receive (STR), the full multi-radio implementation of Multi-Link Operation that manufacturers use to justify the upgrade.
STR is what network device manufacturers promised. It uses multiple radios inside a router to transmit and receive data across several frequency bands at once. What buyers actually get is Enhanced Multi-Link Single Radio mode. That version relies on one radio monitoring available bands and switching between them. It improves upon older band steering techniques, which often caused connection drops or forced devices onto congested frequencies, but it does not split traffic simultaneously as advertised.
The gap between marketing and engineering reality creates immediate financial consequences for households and small businesses upgrading their networks. A mixed environment, where a new Wi-Fi 7 router connects to existing Wi-Fi 6 access points, neutralizes MLO entirely. Only Wi-Fi 7 supports any form of the technology. Devices tethered to older nodes operate exactly as they did before the upgrade.
Client hardware presents an equally rigid bottleneck. Smartphones, laptops, and network interface cards must be Wi-Fi 7 compatible to process MLO signals. For the vast majority of users who have not overhauled every connected device in their home or office, enabling MLO introduces network instability rather than performance gains.
Router manufacturers handle this incompatibility differently. Most ship devices with MLO disabled by default to prevent conflicts with older hardware. ASUS ships at least some models with the feature turned on. Users managing UniFi and eero equipment toggle MLO through mobile apps, while Linksys requires navigating a web interface.
Network administrators and consumers with fully Wi-Fi 7-capable device fleets can test STR alternatives by toggling the setting on and off to benchmark actual throughput differences. Those operating mixed-generation networks or relying on older client devices should verify their router settings and leave MLO disabled until both ends of the connection support the standard.
