Linksys WRT600N Running DD-WRT Wireless Devices Not Communicating With Wired Devices

If you are having trouble communicating between the wired and wireless networks after installing or upgrading your Linksys WRT600N wireless router with dd-wrt firmware then the issue is likely related to the VLAN configuration. After you flash the firmware on a Linksys WRT600N you will have the default dd-wrt settings. One of these settings includes separating the wired and wireless traffic because this is the correct way to secure things because the wireless network is much more likely to be breached than the wired network. Switching this setting to allow communication between wired and wireless devices is easy by following the directions below.

  1. Login To WRT600N: Visit the web administration GUI at your routers internal IP address using the HTTPS protocol. If HTTPS is not set up then you should first configure that before you proceed.

Upgrade a Linksys WRT54G Version 5 Wireless Router Firmware

Upgrading a Linksys WRT54G v5 wireless router is a bit more complicated than most of the other Linksys WRT54G wireless routers. It is not as easy as downloading a dd-wrt .bin file and uploading it via the router administration GUI. Instead you must first install some other bin files to wipe the wireless router clean and then install the dd-wrt software.

Follow these instructions and your wireless router will be running dd-wrt software in no time.
