Wireless Routers vs. Wired Connections
Comparing Networking Options:
Wired Connection Speeds
Wired connections can achieve extremely fast speeds, which work well if you have a fast broadband or fiber-optic Internet connection, making wired options superior to wireless when it comes to speed. These speeds are almost always theoretical maximum speeds, so you will probably see a lower speed in actual performance, depending on the actual conditions.
Ethernet: These connections for home routers and computers typically support transmissions up to 100 megabits per second (Mbps).
Phone-line: A phone-line connection between your network router and computer can allow for varying speeds from 1 Mbps to 128 Mbps, depending on the hardware you have available.
Power-line networking: This option, which uses the existing power outlets and electrical wiring to transmit network signals, can be a cheap solution although it only supports speeds up to 14 Mbps.
Wireless Connection Speeds
Wireless networks are also typically rated with theoretical maximum speeds, so these numbers may not reflect actual performance. In general, you’ll get slower performance from a wireless connection than from a wired connection. Wireless routers, laptops and other devices typically use one of the following signal standards.
802.11a: Also known as “Wireless-A,” this wireless standard can transfer at speeds up to 54 Mbps.
802.11b: Wireless-B networks are slower, only transferring at 11 Mbps.
802.11g: Wireless-G is backwards-compatible with wireless-B although an older device will obviously operate at the slower of the two speeds. Wireless-G devices can transfer at up to 54 Mbps.
802.11n: Wireless-N promises transfer rates of up to 600 Mbps although actual reported performance is much lower, depending on other conditions and what type of hardware you’re using.
A wired connection is rather simple to set up. All you need is a connecting cable from your computer to your router or modem. You may need to change some settings to get your computer to recognize the connection. Wireless networks take a bit more work to set up, and you’ll need to place the router in a location where your computers will receive a clear signal. You’ll also need to set up security settings and a network passkey, which you’ll need for every single computer on the network. Depending on your wireless router and the operating system software running on each computer, you may have to install additional software or change the network settings to get the computers to recognize the connection.
Wired connections only require that your computer and network devices be compatible with a technology like Ethernet or HomePNA. Ethernet is the most widely used wired connection for desktops and laptop computers, requiring an actual Ethernet port. If you don’t have the appropriate port, you might be able to install an Ethernet adapter card that adds the port to your computer. Wireless networks, in comparison, need no connection ports. Instead, you’ll need wireless capability that uses a signal compatible with your wireless router’s signal. This means that many different Wi-Fi devices can use the network as long as they use the right signal. If your computer doesn’t have built-in wireless, you can add that capability by installing a wireless-network adapter through a USB port.
Wireless networks do pose some security risks because they are usually being broadcast in public spaces. Wireless signal encryption offers some protection, but wireless is still not as secure as Ethernet and other wired connections that are not broadcast.
