Possible cause and solutions
No LAN connection
ì
Make sure the connected device is turned on.
ì
Check whether the Ethernet cable is plugged in.
ì
Check that you are using the right cable type
(CAT5) and that the cable is not too long (100m).
ì
Check that the network card on the connected
device and the cables are not defective. If neces-
sary, replace a defective network card or cable.
ì
Use the Windows device manager (My Computer –
Properties) to check whether the network card is
functioning. If you see a red cross or a question
mark, the driver may not have been installed or
there is a resource conflict. Follow the Windows
instructions to remedy the problem.
ì
Check whether the data entered for your Internet
connection matches what your Internet service
provider has specified.
The wireless network adapter is not using the cor-
u
rect SSID.
ì
Change the SSID on the network adapter.
Either encryption has been activated on the Gigaset
u
SX762 WLAN dsl but not on the wireless network
adapter or it is using the wrong key.
ì
Activate the desired encryption (WPA-PSK or WEP)
on the network adapter with the correct key.
If you do not know what the key is, you must re-
enter (page 69) the key via a PC connected via
cable to the Gigaset SX762 WLAN dsl and then
enter the new key on the network adapter.
Alternatively, you can reset the Gigaset SX762
WLAN dsl (page 20) and then reconfigure encryp-
tion.
Warning: Please bear in mind that this will return
all the configuration settings to the factory set-
tings.
