The possible distance between devices in 802.11b or 802.11g networks is 300 feet, while the wireless network
range potentially doubles in 802.11n networks. The range of your wireless network depends on many factors,
including the abilities of your access point and wireless network adapters. If you are having trouble printing, then
try placing the computer and printer no more than 100 feet apart.
You can find the signal strength of the network on the network setup page.
