Password incorrect after updating belkin firmware
On the Linksys WRT54G routers, you need to flash an image that contains the "W54G" header (Linksys and mini_wrt54g images) If pinging 192.168.1.1 does not work, check the IP Address of your computer and make sure it is assigned an IP address in the subnet of the router IP.
For simplicity sake you can assume "192.168.1.x" is good.
Another tftp program is called tftp2 and is available here (this will start the download): tftp23CDaemon from 3Com is another useful tftp program.
To use it, use the TFTP client portion, enable RFC1784 timeout with a 60 second value and set the transfer to Octet.
Belkin has provided ways to access either the control panel or network even if you have forgotten these passwords or you're using a secondhand router.
Press and hold the WPS button on your Belkin router to enable Wi-Fi Protected Setup, which will allow compatible wireless devices to connect without entering a password.A hard reset means resetting the router using the physical Reset button on the outside of the router (usually on the back, next to the internet ports).Hold the Reset button for approximately 15 seconds to force the router to restore itself to its default condition, which reinstates the default password and username combination.Simply clicking the log in button will give you access to the control panel.Log in to your router control panel and Wi-Fi Protected Setup to allow wireless users who are accessing the network for the first time.
