Frequently Asked Questions

I have a wireless keyboard/mouse; do I need a wireless card?

No, you do not. Wireless keyboard and mice do not use the same wireless technology as wireless networking and come with their own USB adapter that needs to be plugged into the computer. Some keyboard and mice use Bluetooth and some use infared signals, it all depends on your exact model of keybaord and mouse.

What is the difference between Wi-Fi and Bluetooth?

While both Wi-Fi and Bluetooth are wireless networking standards, they are used for two completely different tasks. Wi-Fi is used to connect computers and some shared devices (such as printers, network attached storage, etc.) to both each other and to the internet. Bluetooth is primarily used to connect single-system peripheral devices such as keyboards, mice and headsets to a computer.

What kind of security should I use with my wireless network?

There are three main wireless security protocols (commonly referred to as wireless encryption): WEP, WPA and WPA2. Out of the three, WEP should be avoided whenever possible due to its lower level of security. WPA and WPA2 are both relatively secure, although WPA2 is a bit better from a security standpoint. WPA2 does require a hotfix in order to work with Windows XP, however, so it may not be the best choice for all wireless networks. 

Is a wireless network or a wired network faster?

In general, a wired network will be faster and more stable than a wireless network. The main advantage of wireless networking is mobility and the lack of physical wires.

How many devices can be on a wireless network?

While the exact number of devices will vary based on the hardware, most home or business users will never run into a physical limit. The more devices on a network, however, the slower the network will run. Even through there are no physical wires, a wireless access point can still only handle a certain amount of data at a time.

Is a 2.4 GHz or a 5 GHz network better?

A 5 GHz network will likely be faster and be less affected by ambient interference, but has a much shorter range than a 2.4 GHz network. Please refer to the first page of this article for more detailed information

My wireless device is supposed to run at 300Mbps, but I'm not getting the full speed. What's going on?

The speeds advertised on a device are theoretical speeds that are for all intents impossible to achieve. In the best case scenario, you should expect real world speeds of around 40% of the advertised speed. Depending on factors such as signal strength and interference, the real world speed can even be as low as 10% of the advertised speed. Please refer to page two of this article for more information on what affect wireless speed and benchmarks comparing the real world versus advertised speeds.
