This is a rant. This is only a rant.
It's another day in wireless hell. I get a call from one of my coffee shop wireless hot spot managers. None of the customers can see the SSID of their wireless router. I arrive the next morning, and sure enough, their SSID doesn't appear. However, there's a new SSID = dd-wrt which means that their router has been reset to the defaults. Grrr...
I restore the WHR-HP-G125 settings from a backup and verify that things are working normally. DD-WRT 2.4 did some weird things, but I worked around it. I also changed the passwords for good measure. That was the easy part.
Incidentally, I counted 24 customers and 16 laptops in the coffee shop.
This is not the first time their router setting magically went to defaults. The first time, I assumed it was just a "power glitch" as the building wiring was rather marginal. The 2nd time, I assumed a "power surge" as one wall wart and a different router were destroyed. However, this third time, I was fairly sure it wasn't power as I had a ferro-resonant voltage regulator in line, and the building wiring had allegedly been fixed.
I casually and diplomatically interrogated various employees to see if I could reconstruct what happened. I eventually found the culprit in the form of a helpful university student. His logic was impeccable. He said that when his cell phone, cable modem, game machine, calculator, computer, PDA, or whatever was hung, he would just push the reset button. The device would reboot and everything would work fine after that. He reasoned the wireless routers must work the same way. If the wireless was hung or lost connectivity, he would take a paper clip and punch the reset button. After all, it should work the same way as all the other devices with reset buttons.
What could I say? He's right. It *SHOULD* work the way he expected, but as anyone who has ever dealt with a wireless router, it usually doesn't. In my never humble opinion, once again, the wireless industry has screwed up on conventions[1]. Linksys had the right idea. A short tap of the reset button just reboots the router. Longer than about 20 seconds, resets the setting to defaults, except in the WRT54G v8, where it vaporizes most of the firmware.
[1] The other screwup is shipping routers that are not "secure by default".
