WLAN troubleshooting

If DHCP is being used but it failed to retrieve the

address, then an IP address starting with 169.254.x.x

is shown. Sometimes it might take a while (up to 2

minutes) for Nokia 9500 Communicator to receive IP

settings from the server.

If the IP addresses still appear incorrect, you can try

the following two solutions:

1Disable WLAN power saving. To access the setting,

select Desk→ Tools→ Control Panel→

Connections→ Wireless LAN.

2Try using manually configured IP settings instead of

DHCP. Notice that this requires that you have

acquired the appropriate IP settings for the

particular network. You should request them from

the network administrator.

•Wrong proxy settings: if you cannot browse the Web

even though the WLAN connection is working and the

IP settings seem to be correct, check that the HTTP/

HTTPS proxy settings are defined correctly in the

Internet Access Point settings.

•Problems with the WEP security mode: if you

encounter these, check that the WEP keys have been

entered in the correct format (ASCII vs. HEX) and have

the right number of characters. ASCII WEP keys are

also case sensitive; check that you have not confused

any upper or lower case letters in the key.

Incorrect WEP keys may cause a situation where Nokia

9500 Communicator is able to associate with a WLAN

network (the “W” icon with a box graphic is visible)

but no data can be transferred.

Also remember to check that the WEP authentication

mode is c or rec t. In t he ac ces s point it may be called, for

example, “WEP authentication”, “shared-key

authentication” or “Wi-Fi security mode”.

•Poor signal quality: to check the signal quality of your

WLAN connection, select Desk→ Tools→ Control

Panel→ Connections→ Wireless LAN→ Networks.

If the signal quality is weak or even moderate, you may

encounter connection problems. Try again nearer the

access point.

•Wrong security mode: if the “W” icon is displayed but

not surrounded by a box or lock graphic, the configured

security mode may not be the right mode. To check the

security mode that the network uses, select Desk→

Tools→ Control Panel→ Connections→ Wireless

LAN→ Networks. Select the network and press

Details.

•Problems with the WPA or 802.1x security mode: if

you encounter these, check the following:

1Check that the WPA mode is the right one (pre-

shared key or EAP).

2Check the pre-shared key.

3Check that all EAP types that are not needed are

disabled.
