I must be on a roll loading all my old ass Linksys devices with current builds of dd-wrt. Here's how I loaded the July 1, 2016 build 30082 micro generic on a Linksys WAP54Gv3.1 to give it the most recent build from it's original stock Linksys/Cisco firmware.

The wiki for this unit located at is 5 years out of date. You can follow those directions if you like for an older version, but I want to try current build.

Starting from Linksys Firmware Version: v3.04, Dec 27, 2007

Upgrading from stock firmware to 14929 located at
Then upgrading to 30082 located at

Set laptop static IP Gateway and plug in ethernet to back of WAP54G

Log into via web browser
Administration->Firmware Upgrade
Browse for the correct micro build 14929 and click the Upgrade button.
It appears to load and then gives an error upgrading message. Ok, no problem.
Reboot WAP54G and do a 30/30/30 on it.

Ping to verify it's live.

Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 2ms, Average = 1ms

Ok, launch gui tftp.exe and select the 14929 build. Point the IP to and Flash it. It should go through pretty quickly. You might want to wait 5 minutes if you have a flaky unit, but if it flashed properly with a dd-wrt build, it should be responding on as the default IP now. Start a ping to that IP and once it responds, you can log into it via web browser. You'll be presented with the default change password screen. Do so and log in.

Note that it misreports the Router Model as Linksys WRT54G/GL/GS. Check your LAN MAC and see if it matches the MAC of the router or if it is a generic stock MAC address. The first unit I upgraded went to the generic dd-wrt MAC. The second unit I upgraded kept the correct MAC address.

If the MAC needs to be corrected, proceed to Administration->Commands and enter the following, replacing with your actual MAC address. Running these commands one time under 14929 will correctly identify the MAC and Router Model (WAPver=3). Run the commands. Click 'Save Startup' and reboot the unit.

nvram set et0macaddr=00:xx:00:xx:00:xx
nvram set WAPver=3
nvram commit

After rebooting, verify that the MAC address is correct and that the unit is now correctly identifying as Linksys WAP54G v3.x

According to mrjcd at known working versions for this unit are 25974, 26866, & 27858. There may be other working or preferred builds for specific features. Search the forum if you are interested in those, but I want cutting edge for this 2005 era access point! So we'll want to continue upgrading beyond the 5 year old 14929 release. Smile

Do a 30/30/30 reset now to make sure it will reboot properly into 14929. At this point, you can upgrade to any particular build you want to, but I'll go directly to 30082. Head to Administration->Firmware Upgrade and Browse for the 30082 binary. Click Upgrade. After 5 minutes, the progress bar is still moving, as if it's upgrading. It appears to be hung. Reboot the unit by pulling power cable and reinserting. Hmm, ping to it are responding with TTL 100 instead of 64. Ok, looks like it's gone unresponsive. Load up gui tftp.exe, select the new 30082 binary, point it t and flash. Once it's done, pings will start to time out. After a bit, they will respond with TTL 64. Give it a minute and log back into unit via web browser. Default page with password change is loaded. Do so and log into it. Note that firmware is now listed as Firmware: DD-WRT v3.0-r30082 micro (07/01/16) and MAC should be correct, and model is identified correctly. Do a 30/30/30 reset to ensure everything is correct, then log in again and configure as needed.

The quirk here is that after uploading new build via tftp, give it some time and then power cycle the unit. It should respond to web query after rebooting.

Much thanks to the developers for continuing to support an 11 year old Access Point with updated firmwares to extend the useful lifespan of these units. I use these as additional APs across the building with the same SSID/password, so that users can walk with tablets/phones and seamlessly transition to different APs on the same SSID/password but on different channels throughout the building. My 3rd unit up front speedtests 18 down/22 up with my work connection, so it works great.
