Using the Bridging Option
Use the
Bridging
option to configure the DDW365 to act as a wireless network bridge
and establish wireless links with other wireless access points. To establish a bridge, you
need to know the MAC address of the peer device, that must be in wireless bridging mode
as well. The DDW365 can establish up to four wireless links with other wireless access
points. When wireless devices are in wireless bridging mode, they form a wireless
distribution system that allows computers in one LAN to connect to the computers in the
other LAN.
Caution
Avoid bridge loops when you enable bridging devices. Bridge loops cause broadcast traffic to
circle the network endlessly. This can degrade throughput and disrupt communications.

EDCA STA Parameters
Allows you to prioritize wireless network traffic for receiving
terminals. Access categories are:
AC_BE
– Best Effort, medium throughput and delay. Most
traditional IP data is sent to this queue.
AC_BK
– Background, high throughput. Bulk data that
requires maximum throughput and is not time-sensitive is
sent to this queue (for example, FTP data).
AC_VI
– Video
AC_VO
– Voice
WMM TXOP Parameters
WMM TXOP (Wireless Multi-Media Transmit Opportunity
Parameters) are used to control the Access Category (AC) for
each type of Wireless traffic, including Best Effort (BE),
Background (BK), Video (VI), and Voice (VO) traffic categories.
Transmission rates will automatically adjust for each category.
These settings should be left at their default values. WMM
TXOP Access categories are:
AC_BE
– Best Effort, medium throughput and delay. Most
traditional IP data is sent to this queue.
AC_BK
– Background, high throughput. Bulk data that
requires maximum throughput and is not time-sensitive is
sent to this queue (for example, FTP data).
AC_VI
– Video
AC_VO
– Voice
Short Retry Limit
Short Fallbk Limit
Long Retry Limit
Long Fallbk Limit
Max Rate in 500kbps
Defines how many times the MAC retries to send different types
of packets. If the number of retries reach their limit, the frame is
discarded.
