Auto Channel
Selection
Select this check box for the EMG2926-Q10A to automatically choose the channel with
the least interference. Deselect this check box if you wish to manually select the channel
using the
Channel Selection
field.
If you select the check box, you can click the
Scan Channel
button to scan for and
choose an available channel immediately.
Operating
Channel
This displays the channel the EMG2926-Q10A is currently using.
Channel Width
Select the wireless channel width used by the EMG2926-Q10A.
A standard 20 MHz channel provides transfer speeds of up to 144Mbps (2.4GHz) or
217Mbps (5GHZ) whereas a 40MHz channel uses two standard channels and provides
speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz
channel provides speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select
Auto 20/40
MHz
or
Auto 20/40/80 MHz
to allow the EMG2926-Q10A to adjust the channel
bandwidth automatically.
40 MHz
(channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A
80 MHz
channel consists of two adjacent 40 MHz channels. The wireless
clients must also support
40 MHz
or
80 MHz
. In a location where the environment
hinders the wireless signal, it is often better to use the 20 MHz setting .
Select
20 MHz
if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
802.11 Mode
If you are in the
Wireless LAN 2.4G > General
screen, you can select from the
following:
•
802.11b
: Allows either IEEE 802.11b- or IEEE 802.11g-compliant WLAN devices to
associate with the EMG2926-Q10A. In this mode, all wireless devices can only
transmit at the data rates supported by IEEE 802.11b.
•
802.11g
: Allows IEEE 802.11g-compliant WLAN devices to associate with the Device.
IEEE 802.11b-compliant WLAN devices can associate with the EMG2926-Q10A only
when they use the short preamble type.
•
802.11bg
: Allows either IEEE 802.11b- or IEEE 802.11g-compliant WLAN devices to
associate with the EMG2926-Q10A. The EMG2926-Q10A adjusts the transmission rate
automatically according to the wireless standard supported by the wireless devices.
•
802.11n
: Allows IEEE 802.11n-compliant WLAN devices to associate with the
EMG2926-Q10A. This can increase transmission rates, although IEEE 802.11b or IEEE
802.11g clients will not be able to connect to the EMG2926-Q10A.
•
802.11gn
: allows either IEEE 802.11g- or IEEE 802.11n-compliant WLAN devices to
associate with the EMG2926-Q10A. The transmission rate of your EMG2926-Q10A
might be reduced.
•
802.11 bgn
: Allows IEEE802.11b-, IEEE802.11g- and IEEE802.11n-compliant WLAN
devices to associate with the EMG2926-Q10A. The transmission rate of your
EMG2926-Q10A might be reduced.
If you are in the
Wireless LAN 5G > General
screen, you can select from the following:
•
802.11a
: Allows only IEEE 802.11a-compliant WLAN devices to associate with the
EMG2926-Q10A.
•
802.11an
: Allows both IEEE802.11n- and IEEE802.11a-compliant WLAN devices to
associate with the EMG2926-Q10A. The transmission rate of your EMG2926-Q10A
might be reduced.
•
802.11ac
: Allows only IEEE 802.11ac-compliant WLAN devices to associate with the
EMG2926-Q10A.
