4.0 Configuration
Select HT20 for a 20MHz channel, or HT40 for a 40 MHz Channel.
The 40MHz channel is comprised of 2 adjacent 20MHz channels and
the + and—designate to use the higher or lower of the adjacent
channels.

The Channel-Freq setting allows configuration of which channel to operate on, auto can be chosen where
the unit will automatically pick a channel to operate. If a link cannot be established it will try another
channel.

The Wireless Distance parameter allows a user to set the expected
distance the WiFi signal needs to travel. The default is 10km, so the
VIP4G will assume that the signal may need to travel up to 10km so it
sets various internal timeouts to account for this travel time. Longer
distances will require a higher setting, and shorter distances may
perform better if the setting is reduced.

Advanced Capabilities (Only shown if box is checked)
MPDU Aggregation (Enable/Disable) - Allows multiple data frames to be sent in a single transmission
block, allowing for acknowledging or retransmitting if errors occur.
Short GI (Enable/Disable) - GI (guard interval) is the time the receiver waits for any RF reflections to settle
before sampling data. Enabling a short GI (400ns) can increase throughput, but can also increase the error
rate in some installations.
