Home Wireless Network Security. Wi-Fi Security.


Hackers are always on the look out for broadband wireless internet with little to no security.  That’s why securing your wireless network is important.  First thing you should worry about is selecting the best security for your wireless network and make sure it works with all of your wireless devices.  If your wireless device is too old it may be time to upgrade or replace it.

It is really important to secure your Wi-Fi due to the constant threat of someone using it without your permission. The range of a wireless signal is quite large.   Standard wireless signals reach up to 150 feet indoors and 300 feet outdoors.  In some situations a hacker could access your Wi-Fi from miles away with the right antenna. This is just one reason to choose the best wireless security settings possible.


Passwords should be complex and as long as allowed by the devices that will be connecting to them.  Don’t use simple short passwords because they can easily be cracked in very little time.  Hackers are able to hack simple passwords in no time at all.  It is best to use a complex password that contains a combination of upper and lower case letters, numbers, symbols, and other special characters when allowed.

Good Password Example:

Bad Passwords:

Hackers can use what is called a dictionary attack that contains commonly used passwords.


Following are the types of Wi-Fi security with some basic information about each:

  1. None – Open wireless connections are not recommended unless you are running a public network open to everyone.
  2. WEP provides minimal security and is not recommended.  It takes less than 5 minutes to hack.
  3. WPA-PSK (TKIP) – Provides a higher level of security than WEP however like WEP it is vulnerable to hacking – Another drawback it only supports Wi-Fi speed up to 54 Mbps.
  4. WPA2-PSK (AES) – Better security than WPA-PSK.
  5. WPA-PSK+ WPA2-PSK – Combination of both security types has it’s drawbacks including security issues and is restricted Wi-Fi speed to 54 mbps.
  6. WPA/WPA2 Enterprise – designed for enterprise networks and requires a RADIUS authentication server.

Comparing the security types, the best option seems to be WPA2-PSK (AES). This type of Wi-Fi security gives you a balance of security and speed. With the other security types you will have to compromise either security or speed.  Data transfer rates vary on type of encryption you use on your network.

If you don’t use any wireless devices you should turn off the wireless feature so that there is no wireless access to your network.

What wireless network router should you buy?  There is multiple standards for wireless routers and wireless cards. Wireless a, b, g, n, and now ac has been added to the mix.  Well not to worry most if not all wireless routers are backwards compatible with the old wireless standards.

Now the newest wireless standard to come out is 802.11ac that will roll out with even faster wireless speeds.
802.11ac Speed

With any new wireless technology speed is always the headline-grabbing feature but, as with every wireless standard to date, the figures tossed around can be highly misleading.

1.3 gigabits per second (Gbps) is the speed most commonly cited as the 802.11ac standard. This translates to 166 megabytes per second (MBps) or 1331 megabits per second (Mbps). It is vastly quicker than the 450Mbit per second (0.45Gbps) headline speeds quoted on the highest performing 802.11n routers.
So wireless ac is roughly 3x as fast as wireless n? No.

These figures are ‘theoretical maximums’ that are never close to being realised in real world scenarios. In our experience wireless n performance tends to top off around 50-150Mbit and our reviews of draft 802.11ac routers have typically found performance to be closer to 250-300Mbit. So 2.5x faster when close to your router is a good rule of thumb (though far more at distance, which we’ll come to shortly).

Happily this gain is likely to increase as 802.11ac devices advance. Wireless 802.11n supports a maximum of four antennas at roughly 100Mbit each, where 802.11ac can support up to eight antennas at over 400Mbit each.

Smaller devices like smartphones tend to fit only a single antenna, but it gets even bigger in tablets (typically two to four antennas) and laptops and televisions (four to eight). In addition no 802.11ac router released so far has packed more than six antennas.

A final point: beware routers claiming speeds of 1,750 Gigabits. It is a marketing ploy where the manufacturer has added the 1.3Gbit theoretical maximum speed of 802.11ac to the 450Mbit theoretical maximum speed of 802.11n. Sneaky.

802.11ac Range
While speed is what will likely sell 802.11ac routers, range is equally important. Here wireless ac excels.

The first point to make is the 802.11ac standard lives entirely in the 5GHz spectrum. While some more modern routers broadcast 802.11n in 5GHz as well as 2.4GHz they remain relatively rare.

Consequently, the 5GHz spectrum tends to be ‘quiet’, meaning much less interference from neighbourhood Wi-Fi. This more than counters the fact that, in lab conditions, 5GHz signals do not actually broadcast as far as 2.4GHz signals. 5GHz is also necessary to support the faster speeds of wireless ac.
The second key factor is 802.11ac makes ‘beamforming’ a core part of its spec. Rather than throw out wireless signal equally in all directions, WiFi with beamforming detects where devices are and intensifies the signal in their direction(s).

This technology has been around in proprietary form (it made a huge impact in the D-Link DIR-645), but now it will be inside every 802.11ac router and every 802.11ac device.

The combination of these two technologies is profound. This was most clearly seen with the Linksys EA6500 which hit speeds of 30.2MBps (241.6Mbit) when connecting to a device just two metres away, but still performed at 22.7MBps (181.6Mbit) when 13 metres away with two solid walls in the way. By contrast Linksys’ own EA4500 (identical except being limited to 802.11n) managed 10.6MBps (84.8Mbit) dropping to 2.31MBps (18.48Mbit) under the same conditions.

The real world result is 802.11ac not only enables you to enjoy the fastest 100Mbit (and beyond) fibre optic broadband speeds all over the house, but to enjoy it along with multiple streams of Full HD content, super low latency gaming and blazing fast home networking all at the same time.

802.11ac Availability
Here comes the first caveat. The announcement of the Wi-Fi Alliance’s 802.11ac certification programme means 802.11ac equipped products can now be certified, but that process will take time as thousands of chipsets need to be tested.

Of course some manufacturers have jumped the gun. The 802.11ac routers we have tested are sold as ‘Draft 802.11ac’ products and while many may become certified through a firmware update, it is not guaranteed. Draft 802.11ac products are also not guaranteed to perform optimally with other Draft 802.11ac products – especially between different manufacturers. Certified products are.

The good news is the first certified chipsets are already creeping out and they come from the likes of Intel, Qualcomm, Cisco, Realtek, Marvell, Broadcom and Samsung – manufacturers with extensive networking expertise and who licence their chipsets to others. For example Intel has only one chipset certified – the ‘Dual band Wireless 7260’ – but it is expected to be at the heart of most Haswell-powered Ultrabooks. The most high profile of these to date is the new 2013 MacBook Air.

Furthermore, adoption should be fast. The first 802.11ac routers carried a hefty premium, but this has dropped quickly to the point where price shouldn’t be a barrier to anyone keen to hop onto the bandwagon. In addition 802.11ac is extremely efficient and it brings power savings compared to 802.11n, meaning it is ideal for mobile devices. The Samsung Galaxy S4 and Samsung Mega phones already pack wireless ac.

As such, while 802.11ac products are only trickling out at present, it will turn into a tidal wave by early 2014.

Should I wait for 802.11ac?
All of which begs the question: should I now buy any device that isn’t 802.11ac compatible? The short answer is no. If you live alone in a small flat where you have no signal problems 802.11n may serve all your needs, but in larger, multi-user homes and homes with network attached storage the benefits of 802.11ac are simply too good to miss out on. Especially when buying devices you expect to keep for a number of years.

The longer answer is 802.11ac is a revolution that will be hard to actively avoid. Wireless ac will be built into most laptops and phones within the next 12 months and routers will increasingly come with it (though ISPs are typically slow to adopt new standards in the routers they give out, so plug an ac router into theirs and switch off their wireless to get around it).

It will take time and money for your home to be fully 802.11ac compatible, but it will be worth it.

One other thing to note.  When picking a wireless network name you should refrain from using the name of the wireless network hardware, or other personal identifiable information.  Instead use some other non offensive name for your wireless network.
