Network configuration 36
devolo WiFi pro 1750e
Mode
In the Mode field, select the desired Wi-Fi communi-
cation standard.
Channel
There are 13 channels available in the 2.4 GHz fre-
quency band. The channels recommended for Europe
are channels 1, 6 and 11. This ensures the frequency
bands of the channels do not overlap and any connec-
tion problems are avoided.
The channel selection default setting is Automatic.
The WiFi pro 1750e regularly and automatically selects
the channels in this setting. In other words, if the last
connected station logs out, a search for a suitable
channel is carried out immediately. If no stations are
connected, the device automatically selects a channel
every 15 minutes.
Channel width
Optimal use of the available frequency band requires
selecting the appropriate channel width.
Max. transmitting power
In this section, you can adjust the Wi-Fi transmission
level to your needs. I.e. if you require a large range,
select High....
Data rates
Only change the preconfigured data rates if
you understand the concept behind them.
Setting the radio data rates entails selecting the data
rates used by the Wi-Fi access point for transmission.
The Wi-Fi access point sends all packets with the lar-
gest possible basic rate. If the distance between the
Wi-Fi access point and the Wi-Fi stations is too large
for this data rate or faults and interference occur, pac-
kets are sent with the next smallest basic rate. At least
one basic rate must be selected. Unicast packets can
also be sent with the supported data rates which are
not basic rates.
You can optimise the Wi-Fi access point either for ma-
ximum range or for the best performance by varying
the data rates. The maximum range is achieved when
the basic rate is set only to 1 Mbps, all data rates, ho-
wever, are supported.
If a Wi-Fi station only supports 802.11b, no basic rates
outside of 1; 2; 5.5 or 11 Mbps (default) can be used.
For optimisation to ensure the best performance, it
makes more sense to exclude all 802.11b clients (CCK
modulation) by having the 1, 2, 5.5 or 11 Mbps rates
both as not supported as well as not selected as basic
rates.
