2.3 Wireless Connection Setup
Introduction
The SpeedTouch™580 features a Wireless LAN Access Point (AP) which behaves as a 
networking hub allowing to wirelessly interconnect several devices to the local (W)LAN 
and provide - via the SpeedTouch™ DSL router - access to the public network, e.g. the 
Internet. 
IEEE802.11g Wireless technology enables these devices to communicate with each 
other in a locally mobile fashion, without the need for a wired environment. The Speed-
Touch™580 is backward compatible with IEEE802.11b. This means that IEEE802.11b 
and IEEE802.11g devices can coexist in the same wireless network.
Wireless basics
The WLAN's 'radio' link is a shared medium. As no physical connection exists between 
the SpeedTouch™ and wireless clients, a name must be given to allow unique identifica-
tion of your WLAN radio link. This is done by the Service Set ID (SSID), also referred 
to as Network Name. Wireless clients must be part of this SSID environment in order 
to be able to communicate with other clients on the (W)LAN - including the Speed-
Touch™.
The IEEE802.11g standard for WLANs allows several WLAN networks using different 
radio channels to be co-located. The SpeedTouch™ supports multiple radio channels 
and is able to select the best radio channel at each start-up.
Note
The different channels are overlapping. To avoid interference with another 
WLAN make sure that the separation (in terms of frequency, i.e. channel 
number) is as high as possible. It’s recommended to keep at least 3 channels 
between 2 different WLAN’s. E.g. if there is an access point at channel 5 and 
an access point at channel 11, then the SpeedTouch™580 will select 
channel 1.
The SpeedTouch™580 supports all channels allowed for wireless networking according 
to your region’s regulations.
However, depending on local regulations, the number of channels actually allowed to be 
used may be additionally restricted. As shown in table below:
