Wi-Fi systems reach further than ever at CES 2017

The Linksys Velop comes with three identical hardware units that wirelessly link together using a dedicated 5GHz band. This band allows the Velop to deliver great coverage and consistent speed. The system is available now at $500 (about £405 or AU$685) for a set of three.

Asus HiveSpot has similar hardware specs to the Linksys Velop and also includes real-time online protection against malware and cyber threats. It's also cheaper at just $400 (about £325 or AU$550) for a set of three. It won't be available until the second quarter of the year.

TP-Link's first Wi-Fi system is very similar to the Eero plus the option to use Powerline to connect different units together. The device won't be available until later this year.

The Norton Core is a powerful router that has built-in online real-time protection for the entire network. It's available in Spring and costs $280. After a year, you'll have to pay $99 a year if you want to keep the protection. Symantec says the Norton Core is "mesh ready" and it will announce the additional units at a later time.

UK and Australian availability was not announced, but the preorder price converts to about £165 or AU$275.

The Advanced Gateway is a full Wi-Fi solution and will work with extenders to seamlessly increase Wi-Fi coverage. Comcast says it will announce the details of the extenders in a few months when the gateway is available.

The Portal is a powerful router by itself. And when two Portals are used together, they become a Wi-Fi system with large coverage.

The D-Link Covr Wi-Fi system looks like a standalone router and an extender, but don't be fooled by appearances. It offers seamless hand-off and other features that only a Wi-Fi system would have. It will be available in the second quarter of the year and costs $300, which converts to about £190 or AU$300.
