Buying the Right Wi-Fi Router

Are you tied to your broadband modem connection? You can create a high speed wireless network by plugging in a Wi-Fi router to your DSL modem. Here’s what you need to know to pick the best wifi router that suits your small office or home needs.

WiFi Range

The maximum distance wifi can transmit signals. A typical Wi-Fi router can broadcast signals up to 30 meter radius. Depending the position of the antenna, the device around it (mobile phones, wireless phones) this range might be shortened on some sides. Please take note that the 30 meter range is also shortened by about 5 meters for every wall in your house that the signals go through. The material of the wall also affects the range. In a typical house, the range is just about 15 meters especially if the router is in your bedroom and you want to use your laptop from your patio.

Wifi range is also affected from the client side (laptop, notebook, mobile phone). In general, laptops or notebooks will get better signal compared with a mobile phone. So a good signal in your laptop doesn’t necessarily means the same good signal from your mobile phone. So buying a laptop with good wifi adapter also lengthened the range of your wireless network.

Networking Standard

The current standard now for home networks is 802.11n. It is backward compatible with 802.11b/g Wi-Fi adapters or routers. With link rates–the nominal connection speeds, as opposed to real-world throughput–of up to 300 megabits per second (compared with 54 mbps for standard 802.11g) and extended range (thanks to multiple smart antennas), 802.11n Wi-Fi is the first Wi-Fi technology that can rival wired 100-mbps ethernet in performance. Upgrading your home router to 802.11n is thus one of the quickest and easiest ways to improve your network.

Throughput

Throughput is measured in megabits per second or Mbps. It refers to the data transfer speed the router can give. The previous standard 802.11g is rated at 54Mbps which typically transfer data at a rate of 20Mbps. The new 802.11n routers are rated at 300Mbps which can typically move data at 90Mbps which is 4 to 5 times quicker and faster than the B type routers.

Security

Most routers come with Wired Equivalent Privacy or WEP type of encryption. For greater security, get a router with a more powerful Wi-Fi Protected Access or WPA encryption and a built-in hardware firewall.

Suggested Brand

You can never go wrong with either Linksys (Cisco), D-link or Netgear Wi-Fi routers. I’m using D-Link 300 (image above) for more than 2 years now and it still suits my my needs so no reason for an upgrade yet.
