The performance of GPS varies depending on the environment. Failure to
pinpoint a location might happen.
Your current location might not be shown depending on the status of GPS
or the location. If you are obtaining your current location information from
the computer, your current location might not be detected due to the
information accuracy. Specifically, your current location might not be
detected in the following places or situations:

LAN

The computer has built-in support for Ethernet LAN (10 megabits per
second, 10BASE-T), Fast Ethernet LAN (100 megabits per second,
100BASE-TX) or Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T).
This section describes how to connect/disconnect to a LAN.
LAN cable types
The computer must be configured properly before connecting to a LAN.
Logging onto a LAN using the computer's default settings might cause a
malfunction in LAN operation. Check with your LAN administrator regarding
set-up procedures.
If you are using Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T), be sure to connect with a CAT5e cable or higher. You
cannot use a CAT3 or CAT5 cable.
If you are using Fast Ethernet LAN (100 megabits per second, 100BASE-
TX), be sure to connect with a CAT5 cable or higher. You cannot use a
CAT3 cable.
