How Are Infrastructure And Ad Hoc Networks Different; Finding The Signal Strength - Lexmark Pro4000c User Manual

Networking

How are infrastructure and ad hoc networks different?

Wireless networks can operate in one of two modes: infrastructure or ad hoc.
In infrastructure mode, all devices on a wireless network communicate with each other through an access point (wireless
router).
In ad hoc mode, a computer with a wireless network adapter communicates directly with a printer equipped with a
wireless print server.

Same SSID
Same channel
We recommend setting up a network in infrastructure mode using the installation software CD. Infrastructure mode
provides:
•
Increased network security
•
Increased reliability
• Faster performance
•
Easier setup

Finding the signal strength

The signal strength tells you how strongly the computer or printer is receiving the wireless signal from the wireless
network. Poor signal quality could affect connectivity during configuration.
Checking computer connectivity
1
From your computer system tray, click the wireless icon that corresponds to the software managing your wireless
network adapter.
