Question 10. I have configured all the settings correctly, but the
wireless network or the UpnP still does not function correctly .
Answer:
Are you using a firewall such as Norton Internet Security, McAfee Per-
sonal Firewall, Zone Alarm, etc ., or are you even using the integrated
firewall of Windows XP? (Ensure that the Windows XP Service Pack
2 automatically upgrades your firewall and is activated in the works
settings.) If you are using a firewall, this may have to be configured or
may require exceptions to enable you to view and communicate with
the appliance in the network. To check whether your firewall is blocking
the network communication (including PING and file access), interrupt
the connection .
If you can make a connection with the firewall deactivated, you may
have to add the appliance to the "trusted list" or configure the firewall
for the local Intranet access. In the worst case, deactivate your firewall
as long as necessary to allow the appliance to be used . Then activate
it again .
Question 11. I am using the 802.11n WLAN dongle with a wireless
802 .11n router . Why is the transmission rate still only 802 .11g
54Mbps instead of 300Mbps?
Answer:
The IEEE 802 .11n draft forbids the use of high data transmission rates
with WEP or TKIP as Unicast codes . If you are using these encryption
methods (e .g . WEP, WPA-TKIP), your data transmission rate will drop
to 54 Mbps . You can contact the access point or router manufacturer
to download the latest firmware, or try the other encryption methods
(WPA2-AES or WPA2-TKIP); or configure an insecure profile, although
this method is not recommended .
