6 Ways to Improve Your W-iFi Network

3. Disable Really Old Technology

Let's face it, sometimes really old technology just needs to be turned off. Devices that support the first wireless standard, 802.11b, are just too slow and drag down overall performance, Kozup says. "We're advising customers to disable this in their networks," he says. "By doing so, you're speeding up everything else."

Cisco's advice: Because most 802.11b only clients are being phased out in favor of 802.11g or 802.11a/g/n devices, Cisco recommends that organizations disable the lower 2.4 GHz data rates on the WLAN (such as 1 and 2 Mbps).

4. Go with the Higher Frequency

WiFi operates in two unlicensed frequencies, 2.4 GHz and 5 GHz. Most devices, including the iPad, are dual-band clients that can operate in either frequency. "The fact of the matter is that the 5 GHz frequency is much cleaner, much more space than the 2.4 GHz," says Kozup, "so we want to make sure those iPads are connecting as frequently as possible into the 5 GHz frequency."

The problem is that dual-band devices tend to connect into the 2.4 GHz. Cisco has come out with a product called BandSelect that automatically gets dual-band devices to use the 5 GHz frequency.

Cisco's advice: Because 5 GHz has eight times the spectrum of 2.4 GHz, and it is usually less congested, Cisco BandSelect helps make sure that clients that can use the 5 GHz bands do so. This helps free up 2.4 GHz in mixed client environments.
