AirCard Hub User Guide

If your wireless signal seems weak in some spots, make sure that objects such as

those listed above are not blocking the signal’s path (between your devices and the

AirCard Hub).

Cordless Phones

If the performance of your wireless network is impaired after considering the above

issues, and you have a cordless phone:



Try moving cordless phones away from your AirCard Hub and your wireless-

enabled computers.



Unplug and remove the battery from any cordless phone that operates on the

2.3 GHz / 4 GHz band (check manufacturer’s information). If this fixes the

problem, your phone may be interfering with the AirCard Hub.



If your phone supports channel selection, change the channel on the phone

to the farthest channel from your wireless network. For example, change the

phone to channel 1 and move your AirCard Hub to channel 11. See your

phone’s user manual for detailed instructions. If necessary, consider

switching to a 900 MHz or 5 GHz cordless phone.

Choose the “Quietest” Channel for your

Wireless Network

In locations where homes or offices are close together, such as apartment buildings

or office complexes, there may be wireless networks nearby that can conflict with

your wireless network. Use the Site Survey capabilities found in the software provided

with your wireless adapter to locate any other wireless networks that are available

(see your wireless adapter’s user manual), and switch your AirCard Hub and

computers to a channel as far away from other networks as possible. Refer to section

Wireless LAN (WLAN) on page 40.

Experiment with more than one of the available channels, to find the clearest

connection and to avoid interference from neighbouring cordless phones or other

wireless devices.
