While the decision may initially seem arbitrary, the fact is that different models of wireless routers can have drastically different results based on your individual network. There are a number of things to consider when purchasing a router, and cost is only one of them.You will usually find speed ratings on the box advertised in megabits per second (Mbps). Draft N routers may look tempting with their 300 Mbps ratings, but this is a test-value only. In reality, most people only achieve a fraction of that speed, so a more modest 802.11g router (with a speed of 54 Mbps) may not be such a bad idea. The other most common thing people look for, and with good reason, is sales rankings. Even if this doesn’t include the models that are later returned, numbers are a good indication that that device works, even if it isn’t cutting-edge technology.Before purchasing, make sure you’ve checked out the warranty packages for different models. Paradoxically, the products with longer warranties will usually indicate that the router is more reliable and guaranteed to last (at least until the warranty expires). Routers with shorter warranties are usually lesser products, which the companies are hoping will outlast their package. You can check out reliability ratings and reviews online, but beware putting too much stock into personal anecdotes. Routers can produce different results depending on how they are set up, or how well the home network is connected. This isn’t to say that you should ignore a product that has only bad reviews, but don’t let a mixture of good and bad ratings distract you too much.Brand matching is something to consider if you’re looking to squeeze every last bit of processing power out of your network adapter. Companies often optimize products with their own equipment, and compatibility is more guaranteed. Finally, consider if size/style will be a factor in your decision. Businesses will have more use for smaller, more portable routers, while home owners may want something that goes with the wallpaper.
