then present this value to the owner of access point so he / she can add the MAC address

of your network card to his / her access point’s list.

Q. The network is slow / having problem when transferring large files

1. Move closer to the place where access point is located.

2. Enable ‘Wireless Protection’ in ‘Advanced’ tab.

3. Try a lower TX Rate in ‘Advanced’ tab.

4. Disable ‘Tx Burst’ in ‘Advanced’ tab.

5. Enable ‘WMM’ in ‘QoS’ tab if you need to use multimedia / telephony related applications.

6. Disable ‘WMM – Power Save Enable’ in ‘QoS’ tab.

7. There could be too much people using the same radio channel. Ask the owner of the access

point to change the channel number.

1. What is WMM?

Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the user

experience for audio, video and voice applications. WMM is based on a subset of the IEEE

802.11e WLAN QoS draft standard. WMM adds prioritized capabilities to Wi-Fi networks and

optimizes their performance when multiple concurring applications, each with different latency

and throughput requirements, compete for network resources. By using WMM, end-user

satisfaction is maintained in a wider variety of environments and traffic conditions. WMM

makes it possible for home network users and enterprise network managers to decide which

data streams are most important and assign them a higher traffic priority.

2. What is WMM Power Save?

WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency and

flexibility of data transmission in order to conserve power. WMM Power Save has been

optimized for mobile devices running latency-sensitive applications such as voice, audio, or

video, but can benefit any Wi-Fi device. WMM Power Save uses mechanisms included in the

IEEE 802.11e standard and is an enhancement of IEEE 802.11 legacy power saves. With

WMM Power Save, the same amount of data can be transmitted in a shorter time while

allowing the Wi-Fi device to remain longer in a low-power “dozing” state.

3. What is GI?

GI stands for Guard Interval. It’s a measure to protect wireless devices from cross-

interference. If there are two wireless devices using the same or near channel, and they are

close enough, radio interference will occur and reduce the radio resource usability.

4. What is STBC?

STBC stands for Space-Time Block Coding, which is a technique used to transfer multiple
