Ultimate Router Guide: How to Optimize Security and Performance
How To Maximize Your Router Speed & Strength
1. Location, Location, Location
Its true in real estate, and its true for routers, finding the right location is one of the most important steps you can take to boost your routers performance. Most new consumer grade routers ship with Omni-directional antennas. This means it broadcasts your signal uniformly in a 360-degree radius. If you need to locate your access point in the corner of your house, a large percentage of its capability is being wasted. If you find you have dead spots in areas of your home, you can replace the antenna with a hi-gain version that will focus your signal in a 180-degree radius, vastly increasing your range in the chosen direction.
2. Change Your Routers Wireless Channel
Selecting the right wireless channel, particularly in older routers, can have one of the biggest single impacts on your speed and range. If your router is operating on the same channel as your neighbor, or if your operating two separate routers close by, sharing a wireless channel basically cuts your performance in half. Most of the third party connection tools that ship with laptops or wireless adapters, will show you what channel nearby networks are on, all you need to do is pick a spectrum that isn’t in use. If you’re using the built in plain vanilla Windows tool, you’ll want to download Network Stumbler to help you find a vacant channel.
Some newer routers have an “auto” option which is designed to monitor and change the channel as needed, but more often then not I find this setting doesn’t work as advertised. The D-Link DIR-655 I used for testing locked on to channel 3, even though a second router sitting directly beside it was operating a separate network on the same channel. Your best bet is to manually select the best channel by determining those of other access points within range. Generally it is best to use channel 1, 6, or 11, if they are available, otherwise choose any available free channel. If you live in an apartment building or a condo you might have a hard time finding an open channel, but then again, you probably weren’t having coverage problems anyway. Based on the screen shot shown above, I would most likely configure my new access point using channel 11, since it will encounter the least amount of interference.
3. Update the Firmware For Your Network Adapters, as well as the Router
This might sound like cheesy and obvious advice, but you would be surprised how many people ignore the firmware on their networking equipment. Many advances, particularly in the draft n devices, are leading to vastly improved performance and stability. A simple update to the DWA-552 XTREME N Desktop Adapter in my test system lead to a near doubling in transfer speeds over the original drivers that shipped with the unit, and added two extra bars of connection strength. Make sure to update the drivers both on your adapters, and your router.
