In response to our article about updating firmware, Bruce H. Miller wrote us saying "Although for the most part I agree with you, I would encourage you to urge your readers to keep a copy of the previous firmware, and or download both before updating. I have attempted to update routers with the firmware only to find the firmware had a flaw. Luckily I could roll back, get back on line, research, and then try again at a later date. Without the older version I would have been dead. Just some advice from having learned the hard way!"
Dave responded "Very good point, Bruce. I'm a strong believer in having a 'roll-back' strategy. The only problem is that most vendor websites have only the current firmware. For example, if I go to the SMC support site and look for the 2804WBRP-G, it has only the 1.002 firmware. The router came with 1.000. I didn't see any way to save 1.000. Perhaps it was on the CD-ROM that came with the router."
