13. Why am I prompted to enter a comment when I am using an Ethernet
connection?
You are prompted to type a comment because Access Connections has found
a new network device for an automatic network connection. Access
Connections recognizes this network as the most suitable one for the current
location profile. The next time you connect to this network, this location profile
is selected automatically.
14. I cannot configure the fixed IP address.
If you select Best Available Network for the network connection type, you
cannot configure a fixed IP address. Select wired LAN or wireless LAN only.
15. Why is the Ethernet location profile not displayed in the automatic
location switching list?
Ethernet location profiles with fixed IP addresses are excluded from the
automatic switching list.
16. If I am using a wireless LAN connection, I cannot log on to the domain.
The wireless LAN network connection is more vulnerable to an unauthorized
access than the wired LAN network connection, because the wireless
connection uses radio waves. If you try to connect to the wireless LAN
network, the authentication process is required. Until the authentication
process is completed, you cannot get access to the network. If it takes a long
time to get access to the network after logging on to Windows, you may not be
able to log on to the domain. Instead, your computer may try to get access to
copies of the most recently requested network that have been stored in the
cache of your computer. If the computer gets access to the copies locally, you
cannot use some functions that are covered by logon script or logon policies.
To make sure that you can log on to the domain, Access Connections starts
the authentication immediately before the process of logging on to Windows is
completed. If you use IEEE 802.1x Authentication, such as EAP-LEAP,
EAP-PEAP, or EAP-TTLS, Access Connections changes the sequence for
logging on, so that the authentication process is completed first. If you use
Static WEP Keys or Wi-Fi Protected Access—Pre Shared Key (WPA-PSK),
refer to the instructions in Wireless security settings section.
17. When I am using peer-to-peer mode, I cannot select channels.
In peer-to-peer mode, because Access Connections searches for suitable
channels for your SSID (network name), you do not need to select channels.
For the wireless standard, IEEE 802.11a/b/g, Access Connection applies the
default setting for the wireless adapter. To change this manually, click
Configure menu in the main window of Access Connections, and select Peer
to Peer Options. If you cannot connect with other members because of
differences between wireless modes, leave the group and select a wireless
mode that all members can use.
