I have an old Airport Extreme, probably about 8 years old. It seems to have gone wonky on me. I've tried everything including resetting to factory defaults. Anyway, the point is I need to replace the unit. However, it is mounted into a wall unit electrical box, which is not deep enough to hold the new style "vertical" Airport Extreme that is meant to sit on a desk. It's about an inch too wide. This new design really sucks for my situation. So, I'm stuck with a choice of replacing it with another used (or I think some are still boxed on Amazon) old-style Airport Extreme, or with another brand unit that does the same thing. Of course I'd rather stay with Apple, as all my Airport Expresses, my Airport Time Capsule and all our devices are Apple. Which is the best choice? And if non-Apple are there any recommendations, warnings?
