SR808ac Cable Modem User Manual
This page allows configuration of the physical parameters of your wireless
network.The MAC address of the wireless interface is displayed at the top of the
page.
Wireless:
Allows the wireless interface to be enabled and disabled.
Country:
Restricts the channel set based on the selected country's regulatory requirements.
Output Power:
Control the range of the AP by adjusting the radio output power.
802.11 Band:
Select whether the radio operates in the 2.4 GHz or 5 GHz band. There may be
less interference from other wireless networks and household devices in the 5 GHz
band, but 802.11b/g devices will not be able to connect.
802.11 n-mode:
Switch this to Off to force the AP to operate in 802.11g mode.
802.11 N Support Required:
If the 802.11 N support required field is set to "on", then only .n capable stations are
allowed to associate with the CM. If it's set to "off" then b/g/n are all allowed.
Bandwidth:
802.11b/g channels are only 20 MHz wide, but 802.11n channels may be 40 MHz
wide. There are some backward compatibility issues with 40 MHz channels though.
These issues are more likely to be encountered in the 2.4 GHz band where legacy
(802.11b/g) devices may be operating using 20 MHz channels.
Sideband for Control Channel (40 MHz only):
Whether the 20 MHz control channel uses the upper or lower half of the 40 MHz
channel. Changes to this setting may change the control channel setting. For
example (in the 2.4 GHz band), if the upper 20 MHz is selected as the sideband for
the control channel, then the lowest control channel available would be channel 5
to allow the lower 20 MHz for data.
Control Channel:
Selects the control channel for AP operation. The list of available channels
depends on the selected country as presented in
Table 1. Next to the drop-down list box, the current channel number is displayed.
