WLAN troubleshooting
Some common problems that may occur when using WLAN
are discussed in this section.
• 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
advanced settings of your WLAN access point.
• 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
E60 is able to associate with a WLAN network but no
data can be transferred.
Also remember to check that the WEP authentication
mode is correct. In the access 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 Menu
→ Connect.→ Conn.
mgr.
→ Act. data conn.→ Options→ Details. If the signal
quality is weak or even moderate, you may encounter
connection problems. Try again nearer the access point.
• Wrong security mode: it is possible that you have
configured the security mode correctly, but it may not
be the right mode. To check the security mode that the
network uses, select Menu
→ Connect.→ Conn. mgr.→
Act. data conn.→ Options→ Details.
• Problems with the WPA/WPA2 or 802.1x security
mode: if you encounter these, check the following:
1 Check that the WPA mode is the right one (pre-
shared key or EAP).
2 Check the pre-shared key.
3 Check that all EAP types that are not needed are
disabled.
4 Check that EAP type settings are correct (passwords,
user names, certificates, etc.).
• Problems with access point configuration: if you
encounter these, check the following:
1 Many WLAN access points contain proprietary
“Turbo” mode’s claiming to enhance data rates.
These functionalities should be disabled from the
IAP if there is any reason to believe that they are
causing problems to legacy WLAN terminals.
2 Many interoperability problems are solved by
updating the IAP firmware to the latest version.
• Not all channels are available: if you use the device
in the offline mode or in the USA, only channels 1-11
are available. Channels 1-13 are available in Europe.
• Finally...: remember that all Wi-Fi certified devices are
unfortunately not compatible, even if they are
supposed to be.
