I have an original Samsung Airave. Its been powered on for years without any issue. The only time I don't see all blue LEDs is when I reboot my router. My whole setup is on a UPS so it is unusual for any device to loose power.
No, but I've only had my airave for about 2 weeks now. Of course I've found out that with it I now get better 3G speeds than 4G in my house. :P -- FractalSphere - "Maybe it's in the basement, I'll go upstairs and check" - M.C. Escher
