Antenna
VigorAP 910C can be attached with two antennas to have good
data transmission via wireless connection. However, if you
have only one antenna attached, please choose 1T1R.
Tx Power
The default setting is the maximum (100%). Lower down the
value may degrade range and throughput of wireless.
Rate Adaptation
Algorithm
Wireless transmission rate is adapted dynamically. Usually,
performance of “new” algorithm is better than “old”.
Fragment Length
Set the Fragment threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is 2346.
RTS Threshold
Minimize the collision (unit is bytes) between hidden stations
to improve wireless performance.
Set the RTS threshold of wireless radio. Do not modify default
value if you don’t know what it is, default value is 2347.
Country Code
VigorAP broadcasts country codes by following the 802.11d
standard. However, some wireless stations will detect / scan
the country code to prevent conflict occurred. If conflict is
detected, wireless station will be warned and is unable to make
network connection. Therefore, changing the country code to
ensure successful network connection will be necessary for
some clients.
Auto Channel
Reselect
Enable – Usually, wireless channel determined by AutoSelect
(Wireless LAN>>General Setup) means Vigor router will
search for a channel with low interference automatically once
the system reboots. However, when the channel utilization is
more than 70% (refer to Diagnostics >> Interference
Monitor), Vigor router will search for and switch another
channel with low interference to obtain better wireless signal
again.
Auto Channel
Filtered Out List
The selected wireless channels will be discarded if AutoSelect
is selected as Channel selection mode in Wireless
LAN>>General Setup.
IGMP Snooping
Check Enable to enable IGMP Snooping. Multicast traffic will
be forwarded to ports that have members of that group.
Disabling IGMP snooping will make multicast traffic treated in
the same manner as broadcast traffic.
