IP address issues

When having a wireless computer switch access from the “-guest” network to the primary one, the Wireless Client List will continue to display the computer under the “-guest” network; but the wireless computer will connect to the main network IP address.

Windows 7 security issues

When the router’s wireless security is turned OFF and you connect a Windows 7 computer wirelessly, it will trigger the Wi-Fi Protected Setup™ (WPS) process.  The router should not treat this as an unsuccessful attempt and you should still be able to connect to the wireless network.

Anti-virus issues

When wireless security is disabled, the Internet blocking page redirect feature of Trend Micro Internet Security Pro 2010™ works slowly, or fails.

Flashing or blinking front panel LED

Other Tips

Creating a shortcut to your USB storage devices

Creating a shortcut or drive mapping to a USB device that is currently attached to the Linksys Wi-Fi Router, E4200 will create a .storage_info file.  It is recommended to keep this file as it contains the storage device’s access configuration.
