The network is slow / having

problem when transferring

large files

1. Move closer to the place where access point is

located.

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

3. Enable ‘WMM’ in ‘WMM’ tab if you need to use

multimedia / telephony related applications.

4. Disable ‘WMM – Power Save Enable’ in ‘WMM’

tab.

5. There could be too much people using the

same radio channel. Ask the owner of the

access point to change the channel number.

Please try one or more solutions listed above.

1. What is the IEEE 802.11g standard?

802.11g is the new IEEE standard for high-speed wireless LAN

communications that provides for up to 54 Mbps data rate in the 2.4 GHz band.

802.11g is quickly becoming the next mainstream wireless LAN technology for

the home, office and public networks.

802.11g defines the use of the same OFDM modulation technique specified in

IEEE 802.11a for the 5 GHz frequency band and applies it in the same 2.4 GHz

frequency band as IEEE 802.11b. The 802.11g standard requires backward

compatibility with 802.11b.

The standard specifically calls for:

A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4

GHz frequency band, known as the extended rate PHY (ERP). The ERP adds

OFDM as a mandatory new coding scheme for 6, 12 and 24 Mbps

(mandatory speeds), and 18, 36, 48 and 54 Mbps (optional speeds). The

ERP includes the modulation schemes found in 802.11b including CCK for

11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.

B. A protection mechanism called RTS/CTS that governs how 802.11g devices

and 802.11b devices interoperate.

2. What is the IEEE 802.11b standard?

The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the

standard for the industry. The objective is to enable wireless LAN hardware

from different manufactures to communicate.
