- The actual transfer speed of USB 3.0, 3.1, 3.2, and/or Type-C will vary depending on many factors including the processing speed of the host device, file attributes and other factors related to system configuration and your operating environment.
- Actual data throughput and WiFi coverage will vary from network conditions and environmental factors, including the volume of network traffic, building material and construction, and network overhead, result in lower actual data throughput and wireless coverage.
- Quoted network speeds and bandwidth based on current IEEE 802.11ac specifications. Actual performance may be affected by network and service provider factors, interface type, and other conditions. Connected devices must be 802.11ac-compatible for best results.
- WPA/WPA2 enterprise is only available on single router, is not available under AiMesh mode.
- When traditional QoS is enabled, there will be limitations due to the actual Internet service bandwidth and different environment, and there may be a risk of speed reduction.
- Due to the different power supply requirements on USB external hard disk and 4G/5G Modem device, to ensure that the external device can be used stably, if the USB external device exceeds the standard USB 2.0 (5V/500mA) and USB 3.1 Gen 1 (5V/900mA) power supply requirements, you need to use it with an independent external power supply.
- If you use the product in conjunction with a third party service, you are responsible for complying with the third party provider's terms and conditions and privacy policy and are also at the risk of such use. ASUS does not provide support or guarantee continuous integration support for products that are not part of ASUS.
- The device is restricted to indoor use only when operating in the 5150-5350 MHz frequency band in certain regions, including the EU, Asia-Pacific countries, Australia, and Canada. Outdoor use in this band may be prohibited or require regulatory approval. Check local regulations before deployment.
- For models with Time machine support, starting with macOS 26 (Tahoe), Time Machine no longer supports creating new backups on USB-connected storage devices. Existing Time Machine drives that were previously configured remain compatible and can continue to be used for backup and restoration.
- The actual transfer speed of USB 3.0, 3.1, 3.2, and/or Type-C will vary depending on many factors including the processing speed of the host device, file attributes and other factors related to system configuration and your operating environment.
