buying a wifi routerOkay, so you need a router. Maybe you already had one blinking away and it’s taken a turn for the worse. Perhaps yours is working fine, but it doesn’t support 802.11n, and you’d like to upgrade. Or it could be you haven’t had any WiFi at all, in which case – welcome to 2012! We’re glad you could join us.

Many people find that they don’t know much about routers when it comes time to buy one. There’s no shame in that. Consumers usually don’t bother to learn much about them because we don’t often interact with them directly unless they’re broken.

There are some important differences between routers, however, so it’s a good idea to brush up on your knowledge before making a purchase.

Wi-Fi Standards – Buy 802.11n

buying a wifi router
The first thing you should learn about is Wi-Fi standards. Many users have heard of terms like “802.11n” but don’t fully understand what they mean. I wrote a guide covering wireless standards last year and, despite being over a year old, it’s still entirely relevant. I suggest that you read it for the full scoop Understanding the Most Common Wi-Fi Standards Understanding the Most Common Wi-Fi Standards Wi-Fi can be a bit confusing because there are a handful of different standards being used. Here's what you need to know. Read More .

For the too-long-didn’t read crowd, here’s the summary. You should buy an 802.11n router no matter what. Routers supporting this standard can be had for as little as $40 and are backwards compatible with 802.11g (but Wireless-g devices will not benefit from 802.11’s increased bandwidth). In fact, many smaller retail stores no longer bother stocking 802.11g routers.

There is a new standard on the block called 802.11ac. You can buy some routers that support it today, but the standard is not out of “draft” status, which means it has not been finalized. I am not aware of any devices currently on the market with native 802.11ac support. Your router might offer it, but you won’t be able to take advantage of it without buying additional (expensive) adapters.

Data Rates – 300 Mbps Is The Sweet Spot

buy a wifi router

Since we’ve already established you should buy an 802.11n router it’s a good idea to now talk about what kind of 802.11n router you want.

Yes, there are different kinds of 802.11n routers. They are separated by their maximum data rate. If you walk into a store and start looking at boxes you’ll notice that most list 150 Mbps or 300 Mbps while some expensive models offer up to 900 Mbps.

The maximum data rate of a single 802.11n data stream is 150 Mbps. However, the standard supports technology known as Multi-In Multi-Out (aka MIMO). This allows the use of simultaneous data streams to create one big, fat stream of data.

Sounds great, right? But there is a catch. Both a device’s adapter and the router must support multiple data streams. If one supports less than the other you will be restricted to the data rate of the slower device regardless of your routers capabilities. And guess what? A lot of laptops, tablets and phones can only use one or two data streams. Also, these are theoretical maximums, not promises. Real-world performance typically falls far short of the rated max.

The best way to find out the data stream support for a device is to look up its wireless adapter on Google and read the manufacturer information. You can find out the adapter used by a Windows 7 computer if you open the Network Connections folder. The model of your adapter will be listed under Wireless Network Connection.

I think that 300 Mbps routers are the ones to aim for. They are not expensive and there are some common laptop and desktop adapters that will support the increased data rate. I don’t recommend buying anything with a higher data rate unless you are absolutely, positively sure you have or are going to buy devices that can use it.

Don’t forget the speed of the wired ports, either! If you have any wired devices (and chances are you do) they’re going to be needed. Some cheap wireless routers skimp on wired ports by only including 10/100 Mbps Ethernet, which can handicap network performance. Make sure the router you buy has GigaBit Ethernet (1000 Mbps) ports.

Don’t Forget A Modem, Maybe

buy a wifi router

If you are buying a router because you want to replace a router provided by your Internet Service Provider you should be aware that not just any router will work. You need a router with a built-in modem. The modem is the gadget which transfers data from your network to the Internet and back again.

Some routers are made with a built-in modem and will serve you well. If you don’t like your choices, however, you can always buy a separate modem and then connect it to your router via an Ethernet cable.

Whatever your choice, make sure you consult your Internet Service Provider before buying. There may be restrictions on modem compatibility.

Value Added Features

buying a wifi router

The average home network will do fine with a basic 802.11n router that supports a 300 Mbps data stream. You can find many such routers at low prices. But there are some extra features you may be interested in obtaining.

Many routers, even some inexpensive ones, now boast USB ports USB 3.0: Everything You Need to Know USB 3.0: Everything You Need to Know USB 3.0 beats USB 2.0 in so many ways. Here's everything you need to know about why you should always pick USB 3.x when possible. Read More . A USB device that normally does not have wireless network support can be plugged into this port to make it a network device. You can plug in a printer and then use it with any computer on your network, for example. Different router manufactures give this feature different names so be sure to read the fine text when searching for it.

Users who live in multi-use households heavy on high-definition streaming should consider a router that supports dedicated use of the 5 GHz band for media content. Most high-end routers advertise this feature, which can reduce network interference between users trying to stream video and users trying to just surf the web.

Another feature of interest to media freaks is DLNA certification. Devices with this certification are built using certain hardware and software standards to ensure they will work smoothly together. This certification is provided to various bits of home media equipment. Adding a DLNA certified router is a good idea if you own other DLNA equipment.

Finally, if you feel comfortable installing new firmware on a your router or would like to try it, look for DD-WRT support. It is open source router firmware that includes a number of features usually reserved for expensive models like IPv6 support, an advanced firewall and quality-of-service controls. Check out the DD-WRT support page to discover if it can be installed on the router you are interested in.

What About Security?

You only need a router with WPA2 support, the current best standard for Wi-Fi encryption. Virtually all routers support this security feature. Some routers will tout features like easy SSID broadcast control How To Hide Your WiFi Network & Prevent It From Being Seen How To Hide Your WiFi Network & Prevent It From Being Seen Read More or an advanced firewall How Does A Firewall Work? [MakeUseOf Explains] How Does A Firewall Work? [MakeUseOf Explains] There are three pieces of software that, in my opinion, make the backbone of a decent security setup on your home PC. These are the anti-virus, the firewall, and the password manager. Of these, the... Read More . These are fine and sometimes include an easy-to-use interface, but they’re not nessecary.

Conclusion

So, to summarize

  • Buy an 802.11n router
  • Don’t buy a router with a data rate above 300 Mbps unless your devices support it
  • Remember that you need a modem
  • Additional features aren’t a requirement, but nice to have
  • Make sure the wired Ethernet ports are rated for GigaBit (1000 Mbps) speeds
  • Make sure the router supports WPA2 encryption

And that’s about it.

I encourage readers to check out router reviews on CNET and PCMag. All routers are not built the same. Some are a bit quicker and some are easier to use. The requirements above are only what a router needs to be adequate for the average consumer.

    Ok. Sorry to sound like a dummy, but heres my situation. I don't have any Internet at home. I just use my phone, which of course uses all my data. There isn't any place close by for me to log on to use free wifi. If I bought a router, would that be all I need in order to use my phones Internet and not use my data??

    Buffalo is the first manufacturer to make (draft) 802.11ac routers (and NICs, IIRC). 802.11ad is in first draft right now, and will break the gigabit limit.

    IPv6 support will become increasingly important in the near future; this year's World IPv6 Day saw many major websites turn on IPv6 permanently.

    If you are going to buy a router with gigabit RJ45 ports, don't forget to upgrade your wiring to Cat5E or Cat6 for lower transmission errors and the best speed.

    Nice.
    Though I have some questions.
    My router is a WNDR3700 v1
    Even tho it supports 802.11n(so does my lappy) I never seem to be able to get a good speed even if the signal is excellent.
    Router range is very limited and it doesn't have any external antennas so the DIY signal boosters are of no use.
    Will the DD-WRT FW increase the range???
    And yeah I have quite a lot of concrete walls in my house.

      My key question would be if you have insulation between the modem and router. The reason is that if the house/apartment is using insulation facing a particular way, then where you place the Modem/Router will change. I experienced that in my house and had to change the Modem and router placement because the insulation would reflect the signal on one side. So when it failed on side, I reversed the set up and the signal was great. With some N class routers , also, the signal can be helped with a reflector facing towards your destination , since the Linksys N class of generation 1 or 2, had no aerial, so the reflector was the only way to boost a signal from a unit with no aerial.
      Just a thought...

    I disagree with buying a N-class router, there is no need whatsoever in terns of speed.

    I challenge you to find a internet connection which can get up to 300Mbps. No matter how fast the wireless is, it is limited by how fast the router itself receives data.

    • Matt Smith
      July 29, 2012 at 5:23 pm

      There are some pretty fast Internet connections in some parts of the world. I've been told some European countries have access to plans like this (I'm in the states) and they're rolling out some FIOS plans like this in the States as well.

      But more importantly, these access speeds can drastically improve your home network's performance. You want it for the same reason you want GIgabit Ethernet.

    just a small thought wps has, even when disabled, introduced security weaknesses in some routers so you may want to avoid it.

    Sorry to sound dumb but I'm still kind of unsure about this stuff and have been waiting on an article like this to ask a question. Here is the scenario. The computer I use at work, mainly to clock in and enter jobs, is a decrepit Windows 2000 pc that is often frustrating to use. There is no wi-fi and I don't have a 3G signal at my workstation so that i can use my Android. (this is in a basement level room). There is an ethernet hub right beside my computer though. If I plug a wi-fi router into it, is that all I need to get wi-fi for my phone?

    • Matt Smith

    Sorry to sound so dumb, but I'm still just a bit uncertain about this. Here is the scenario. At work my computer is a decrepit Windows 2000 desktop which is often frustrating to use. I don't have a 3G signal for my Android there either, at least not without walking all the way to the back of the big room, away from my workstation, which is impractical except for making an occasional call or text.. No wi-fi at all. But there is an ethernet hut right beside my computer. If I plug a wi-fi router in there, will that be all I need to give my Android access to wi-fi?
