Away from large metal surfaces or water.

Placing the antennas in a vertical position provides the best side-to-side coverage. 

Placing the antennas in a horizontal position provides the best up-and-down coverage.

If you are using multiple wireless access points, it is better if the wireless module and an 

adjacent wireless access point use different radio frequency channels to reduce 
interference. The recommended channel spacing between adjacent wireless access 
points is five channels (for example, use channels 1 and 6, or 6 and 11, or 1 and 11).

The time it takes to establish a wireless connection can vary depending on both your 

security settings and placement. WEP connections can take slightly longer to establish. 
Also, WEP encryption can consume more battery power on a notebook computer.

Configure the Basic Radio Settings

The default wireless mode is 802.11ng. You can change the wireless mode, country, and 
many other radio settings on the Radio Settings screen (described in this section) and on the 
Advanced Wireless screen (see 

on page 549). The 

default radio settings should work well for most configurations.

To configure radio settings, you first need to disable the access point.
