I have two older WRT54GL both v1.1, loaded with Tomato Firmware v1.28.7633 .3-Toastman-IPT-ND ND VPN. Through various upgrades these boxes have run like champs. A week or so back, I added a new WRN3500L with code v1.28.7500 MIPSR2Toastman-RT K26 USB VPN. For about a week everything ran like a champ. Yesterday--everything stopped working. I had to power cycle every device (including my cable modem) to get the network to come back on. One of my WRT54s was locked. . . . power light flashed non-stop. I had to reset it to get it back. It reset back to the default theme, etc., So I re-configured it today, and it looked like all was well. . . but it wasn't. I noticed it had started using 00:90:4C:5F:00:2A as the wireless LAN MAC---just like my other WRT54 had ALWAYS done. It would not work as the single extension (ie., remove the other WRT54 from the system) access point and would not like to the WDS system I have setup. What's more is it killed connectivity on the other WRT54. . . by stealing the MAC address I assume. So does anyone have any ideas? I really need three access points at this point. I've reloaded the one that died with the same code version and performed a 30-30-30 while doing it, just to make sure it was clean. With the wireless off, the WRT54 that is bad seems to be fine. No stability problems or anything else to indicate a problem.
