Standard routers are not wireless capable, so if you want to connect your wireless enabled devices such as your mobile phone, android tablet or ereader for example, you’ll need to purchase a wireless access point for a point of entry.
Standard routers must use ethernet cabling to connect all network devices to your home network, leaving a trail of cabling all over your home, which can also be very expensive.
