1. General Information
Make: Linksys

Hardware Version: 5 or 6
Firmware Version: 1.02.0
MAC Address Info:
WLAN MAC: two higher than LAN MAC.
LAN MAC: labeled on the bottom of the device.
WAN MAC: one higher than LAN MAC.
Example: if the LAN MAC printed on the device is 00:11:DE:AD:BE:EF, then the WAN
MAC is 00:11:DE:AD:BE:F0 and the WLAN MAC is 00:11:DE:AD:BE:F1.

2. Wired Upgrade Procedure
Prerequisites:
• client computer with Ethernet interface and firmware file
• Ethernet cable
• device LAN IP address (referred to below as <Device_LAN_IP_Address>)
• device web interface password
Limitations: None
Firmware Filename: WRT54Gv5v6_v1[2].02.0_fw[X].bin (where [X] is an optional string)
Instructions:
• Connect a wired (Ethernet) client with DHCP enabled to a LAN port on the device with an
Ethernet cable. If you are not served an IP address by the device, you will need to determine
the device LAN IP address (see next step) and manually assign the wired client an IP address
in the same subnet as the device LAN IP address. For example, if the device LAN IP address
is 192.168.1.1, assign yourself an IP address of 192.168.1.11.
• Determine the <Device_LAN_IP_Address>. If the device is running DHCP, the device LAN
IP address is likely the default gateway of your connected client; otherwise, if the device
