For best performance, place the Gateway in a central location, somewhere one (1) meter above the

ground/floor and avoid any object that might block the signal (see above). Ideally place the Gateway on a

table or rack that stands alone in empty surroundings.

Understanding Dual Band Terminology

NL19MESH is a dual band router. The primary differences between the two frequencies are the coverage

and download speed. The 2.4 GHz band provides better coverage and penetrate objects/walls at slower

speeds. On the other hand, the 5GHz band provides less coverage but transmits data at faster speeds. For

example, application which are not mobile and requires better download speed (e.g. video streaming, online

gaming) performs best on 5GHz. However, regular online activities such as browsing, email, social networking

works better on 2.4GHz specially when the device used is portable such as phones or laptops. Having said

that, NL19MESH comes with Band steering enabled, which means you do not have to switch between

2.4GHz or 5GHz. The router does the hard work for you, automatically. The reason of explaining the

terminology here is because the troubleshooting is different. Your Wi-Fi connection on a 2.4GHz frequency

band can also be faster or slower because of interference from other devices. Many household devices use

the 2.4 GHz band, as explained earlier. When multiple devices attempt to use the same radio space,

overcrowding occurs. The 5 GHz band tends to have less overcrowding but limited on coverage. N.B.: Band

Steering is the feature that encourages dual-band capable wireless clients to connect to the faster 5GHz Wi-

Fi while at good coverage area and leave the 2.4GHz Wi-Fi less-crowded; therefore to improve Wi-Fi

performance for all the clients. Band steering is enabled in NL19MESH by default.

Tip: For best performance and user experience, we strongly recommend not to change any Wi-Fi related

settings as default Wi-Fi configuration is optimum.

The limitation of coverage cannot be overcome by tuning settings. However, proper positioning always helps.

Adding one or more CloudMesh Satellite units to your wireless network would be an ideal solution. The NS-

01 CloudMesh Satellite works wirelessly with an NL19MESH Gateway, forming a single powerful Whole Home

Wi-Fi Mesh network coverage. In other words, it extends your wireless network much further than usual, so

you can use your bandwidth hungry applications throughout your mesh network. For more information
