So you’re in the market to buy a wireless router. You’re doing your research to find the best router for you, but you’ve come to a crossroads. You have to make a decision: Do you want to buy a Wireless G, Wireless N or Wireless AC router? But more importantly,what is the difference? What is outdated? Is there an option for me if I just want to do basic things like read email and news? What if I play a lot of games and watch a lot of movies? You’ve come to the right place for the answers, my friend. Lets get you on the right track. By the time we’re done here, you will be able to make a confident decision. You’ll even be able to make recommendations to your friends and family when it’s their turn to buy a wireless router.
We’ll start out with a bit of technical information about each. In the end, we’ll relate this information to making a real-world decision based on your needs.
| Name | Speed | Indoor Range | Frequency | Released |
|---|---|---|---|---|
| Wireless AC | 1 Gbps | 115 Feet | 5 GHz | 2013 |
| Wireless N | 300 Mbps | 230 Feet | 2.4 GHz, 5 GHz | 2009 |
| Wireless G | 54 Mbps | 125 Feet | 2.4 GHz | 2003 |
| Wireless B | 11 Mbps | 115 Feet | 2.4 GHz | 1999 |
The WLAN Standard: 802.11
The Institute of Electrical and Electronics Engineers (IEEE) is an organized group of engineers. They created the standard for WiFi technology which all wireless routers will follow. They called this standard 802.11. All wireless routers at the time were built around this standard. There was no letter designation, such as “G”, “N” or “AC”. This 802.11 standard was released in 1997.
The main problem with this standard was that it was far too slow (about2mbps… MegaBits Per Second). So they improved upon this standard. Today, wireless routers are not manufactured to this standard. This is where the different letter designations come in.
802.11 Enhancements
Before we move on, it’s important to note that B, G, and N are not the only extensions. It would make sense to start with Wireless A, right? That actually does exist. However, these other protocols either did not catch on as fast as others or serve a purpose other than for home networks. For example, Wireless A was released around the same time as Wireless B. However, Wireless B devices were cheaper so they were more popular with consumers. Wireless A devices were mainly used by businesses. So that’s why you won’t hear much about those while you shop for wireless routers for your home network today. If you’re still curious about these “other” standards, you can find good information about them by doing a quick search.Wikipediahas some good information about them, but it’s pretty technical so look out for that! Lets move on.
802.11B / What Is Wireless B?
Routers with only Wireless B are no longer manufactured. However, some newer routers still support wireless B. So, it’s still important that you have some basic information about it. Wireless B supports a maximum theoretical transfer rate of11mbps. The signal is good for up to about150 feet. A downside to a Wireless B device is that it operates at the unregulated2.4GHzfrequency range. This is the same as many common household appliances. Things like cordless phones and microwaves can causeinterferenceif your router is near these appliances. If you don’t place your router or computer near one of these appliances, you should be fine.
802.11G / What Is Wireless G?
Wireless G supports a maximum theoretical transfer rate of54mbps. Like Wireless B, it operates at the unregulated2.4GHzfrequency range. So it has the sameinterferenceissues that Wireless B has. Wireless G isbackward compatiblewith Wireless B devices. Odds are that you don’t have a device that only supports Wireless B, but if you do then this is a benefit. As you can see, the main benefit of a Wireless G router over a Wireless B router is speed.
802.11N / What Is Wireless N?
Wireless N supports a maximum theoretical transfer rate of300mbps with 2 antennas.It can reach up to450mbps with 3 antennas. Though typical speeds are more accurately around130mbpsor less without certain configurations and conditions being met.There will be a detailed post on this in the future. If you are curious, please subscribe to this blog and you will be notified when that post comes.It operates at both the2.4GHz and 5GHzbands. These Wireless N devices can operate on multiple signals (called Multiple In – Multiple Out… or MIMO) and have 2 or 3 antennas. It also hasincreased signal range/power over Wireless G.
802.11AC / What Is Wireless AC?
The next big standard to hit the world is 802.11ac, or Wireless AC. Released in 2013, Wireless AC is sometimes referred to asGigabit WiFi(1Gbps… 1 GigaBit Per Second). It will also have stronger signal strength than Wireless N, giving itgreater coverage area. If you are looking for the latest edge in speed, or if you have a Wireless N router that doesn’t quite cover your whole home, you may want to consider a Wireless AC router.
Wireless G vs N, Wireless AC vs N: Which One Should I Buy?
The real choice here is going to be Wireless G vs N vs AC, because routers that only support Wireless B are no longer manufactured. Besides, Wireless G routers are backward compatible with Wireless B devices.
When You Should Buy A Wireless AC Router
- When you have alarge houseand your wireless G router doesn’t quite reach all the rooms you want it to.
- If you live in ahighly populated area(apartment, mobile/modular park, etc.). A wireless AC router will help because it is new technology, so not many people will be running their home networks on the 5 GHz band. This will give you a very big speed advantage because your router won’t be competing with as many other routers using the same signal. (AC routers run on the 5GHz band while most N routers run on the 2.5 GHz band).
- When you have entertainment systems such asXbox One or Playstation 4playing against other people online AND you want your other computers to be able tostream videoat thesame time without taking much of a performance hit.

When You Should Buy A Wireless N Router
- When you haveseveral computersin your house usinghigh-bandwidthsites such as YouTube or Netflix very often at the same time.
- If you download a lot of large files very often
- When you have newer entertainment systems such as Xbox One or Playstation 4and you are playing against other people online (these devicesdosupport Wireless N out of the box)
- Shop for Wireless N Routers on Amazon
When You Should Buy A Wireless G Router
- When you only have one or afew computersin your house.
- When the great majority of your internet use will be forchecking emailandreading newsor blogs. You should be able to watch YouTube or Netflix videos on a single device at a time.
- When you have older entertainment systems such as Xbox 360 or PlayStation 3and you are playing against other people online (these devices donotsupport Wireless N out of the box, unless you have theXbox E which does support Wireless N)
- Shop for Wireless G Routers on Amazon
More Things to Consider
You will want to make sure the wireless interfaces on your devicessupporteach technology. Not all devices support Wireless AC, for example. Check with the manufacturer of your device to see what technology is supported.
