Ease of use.
Setting up a wireless router can be a daunting task for even the most experienced owner. Consider a router that's easy to set up and use.
Ample wired connectivity.
If you want to share a printer or data on an external hard drive on your network, you'll want a router with USB ports. Unless your network will be completely wireless, experts recommend routers with Gigabit Ethernet ports as well, which are theoretically 10 times faster than regular Ethernet ports.
By not protecting your network with a password, you're more vulnerable to hackers or those looking for free Wi-Fi. Experts recommend wireless routers with WPA2 security encryption, the most secure available.
While tech-savvy users may want the most robust features available, most routers are sufficiently feature-rich for home and small-office use. For mainstream use, consider Quality of Service (QoS) support, guest networking, MIMO or MU-MIMO compatibility, band steering, beamforming and parental controls.
A wireless router's performance has three main elements: speed, range and how well it holds a connection. However, keep in mind that external factors -- notably radio interference -- can affect performance, sometimes profoundly.Source: Consumersearch.com
