Wireless-G Broadband Router with SpeedBooster
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between
the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will
inhibit the signal and reduce range. Start with the Router and your wireless PC in the same room and move it
away in small increments to determine the maximum range in your environment.
You may also try using different channels, as this may eliminate interference affecting only one channel.
I have excellent signal strength, but I cannot see my network.
WEP is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that the same WEP
keys and levels (64 or 128) are being used on all nodes of your wireless network.
How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11 (in North America).
