 |
Here is a tutorial on installing dd-wrt v3.0 on the Linksys EA6500 using tftp client. The router has a built in tftp server that is active for a short period after power-on, so you need to catch it while it is ready to receive.
The previous community post (which is unfortunately linked to from the wiki page for this model)
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=283136
did not work for me: attempting a web upload would throw an "invalid firmware" apparently because of un-signed firmware. TFTP, however, works fine.
Fetch a copy of the firmware from
https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/
I successfully used r44715 (11/03/2020)
Power on the router, and hold the reset button for 15s to reset factory defaults. The LAN port lights flash momentarily. Unplug the router.
Set your PC to a static IP address in 192.168.1.x range, I used 192.168.1.15.
Change directory to where you downloaded the firmware. Set up tftp by running the following commands:
| Code: | $ tftp 192.168.1.1
tftp> binary
tftp> rexmt 1
tftp> timeout 60
tftp> trace
Packet tracing on. |
This will prep the tftp client to re-transmit every second for sixty seconds.
Finally, prepare to upload by typing the following. After you hit enter, plug the router in!
| Code: | | tftp> put linksys-ea6500v2-webflash.bin |
I plugged the router in about five seconds into the re-transmit, and the tftp transfer took off within 30 seconds and took about a minute to complete.
Once the transmit is complete, let the router sit for a few minutes. Then direct a browser to 192.168.1.1, and if you see the dd-wrt login, congratulations.
Note on 32k NVRAM bug: While I don't know much about this issue, it seemed to plague this series of models. The first thing I did after setting the router password was to go to Administration > Commands, and enter the following:
| Code: | | for line in `nvram show | grep =$ `; do var=${line%*=}; nvram unset $var; done |
and click "Save Startup". Then under Administration > Management, click Reboot Router. This reduced my NVRAM from 30k to 22k, which seems to be the popular thing to do. |
