You’ll want to hardwire any computer that doesn’t need to move around, like a desktop, since wired connections are fast, reliable and cheap. They’re far from ideal for devices you pick up and move around, though, like laptops, so for those we use a wireless connection (commonly known as Wi-Fi). Wi-Fi is more than adequate for simple web browsing, though wired connections are ideal if you’re transferring big files, gaming, video chatting or streaming video. Most people have a mix of wired and wireless devices on their network, so most of our discussion today will be focused on wireless routers. Since wireless routers allow for both wired and wireless connections, you can wire up when necessary, and connect over Wi-Fi everywhere else. Wireless Throughput Throughput is the speed at which a router can transfer data. The transfer speed of your wireless connection is dependent on the wireless standard it uses. The most common standards today are 802.11g and 802.11n (also known as “wireless G” and “wireless N”, respectively). Wireless N is faster than wireless G, though routers that support wireless N are also more expensive. Most new devices — like smartphones and laptops — support the faster wireless N.

If you have an older laptop, it might have an older wireless G card inside, meaning it can’t take advantage of wireless N speeds. If you have a mix of N- and G-capable computers, you can turn on a wireless N feature called “mixed mode”, which will let you use both on the same network. You’ll get faster speeds on the wireless N clients and slower speeds on the wireless G clients. Some claim, however, that running both N and G devices on the same network can lower speeds across the network, even between a wireless N router and wireless N computer. So if you want the fastest possible speeds, you’ll probably want all wireless N devices on that network. Wired Throughput The wired half of your router will come in one of two speeds: 10/100 Mbps and 10/100/1000 Mbps (also known as “gigabit”). 10/100 routers are cheaper, but won’t transfer data between computers as quickly as gigabit routers will. If you’re only using your router to connect to the internet, 10/100 is fine, since your internet connection is probably slower than 100Mbps, meaning you wouldn’t be able to actually take advantage of the router’s full speed. If you’re transferring data between computers, however, you’ll want to go with a gigabit router, since it’ll transfer that data much faster than a 10/100 model. Range Wireless routers can only reach so far. If you have a big house and have the router on one side, you might not be able to access the network from the other side of the house. Your range, like your speed, is determined by the wireless standard you use. Wireless N has a longer range than wireless G, so if range is important you’ll want to use wireless N. That said, there are many other ways to connect to your network from afar. Wireless extenders (also called wireless repeaters) are products you can buy that do exactly what they say — extend your network further. Alternatively, you can buy a powerline adapter, which lets you use your home’s electrical wiring to hook a faraway device up to your router with an Ethernet cable (and thus get a faster connection than wireless would allow for).
