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.
- 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.
- Open VLAN Configuration:Open the VLAn configuration page by clicking Setup in the top navigation. You will be required to login if you have not already done so. Once you are logged in click on VLANs which is a new link right below the top navigation menu once you have clicked Setup. The default configuration for VLAN’s will look like the below.
- Modify VLAN Configuration:Now modify the VLAN’s configuration by unchecking the checkmark in the 1 row and the W column. This will now allow you to move that check mark into the 0 row and the W column so now there are checkmarks all the way across the 0 row for W, 1, 2, 3, and 4. Next change the drop down for the 0 row from None to LAN. This is underneath the “Assigned to Bridge” column. Your new settings should look like the below image which is a snapshot of the correct configuration for wired devices to be able to communicate with wireless devices on your new dd-wrt firmware.
- Save and Apply Settings:Once you have verified the settings above click the Save button which will save these new settings to the startup configuration. To add the settings to the running configuration click the Apply button.
That’s it! You should now be able to communicate between the wired and wireless devices on your network. If communication between these devices does not matter for you then you should leave the default settings because again it is way more secure. Also make sure you have some form of encryption (WEP, WPA, WPA2, etc.) on your wireless network.
