Seems our office has "dirty" power so we need to get a line conditioner to keep the airport extreme up and running. At first we thought the problem was with the Airport Extreme, and Apple replaced it, but now I've talked with other people in the building and have found out that other folks have similar problems and this might be the way to go. So, looking for recommendations on equipment. We haven't experience power outages or apparent brownouts, just must be enough fluctuations in the power to kick the Airport Extreme out of whack and kill off our wifi in the office. The fix has been to restart it and all is good for a few hours or a couple days, but it's pretty annoying and you just never know when it's going to happen. At a minimum I'd be plugging in an Extreme, an Express and a Wiebetech backup drive, but could also plug in a laser printer, an inkjet printer and a stereo receiver. Thanks for any help.
