So today I bought the beautiful new ASUS RT-N56U
router I'd been lusting after for some time, got it hooked up and running in about 10 minutes, and have been very pleased with its performance thus far. But as I was setting it up, I read through the included "Quick Start Guide" and saw this line, which worried me.
"Keep the device away from metal obstructions and away from direct sunlight."
I get the metal obstructions part, I think—it probably interferes with the signal, especially the 5 GHz band. But I'm worried about the direct sunlight part—right now, my router lives where the old one did, up on a corner of my mantel that gets some indirect (pretty much never direct) sunlight. The old router (a 10-year-old white Netgear WGR614) appears to have yellowed a bit on the side facing the window, though structurally, it's fine. (We replaced it due to its poor performance, but it was always
pretty poor—I received it as a gift six years ago because its previous owner finally got fed up, just like I did today.)
Anyway, long story short, I'm wondering if anyone can shed some, er, light on why it might be bad for my new ASUS router to get direct sunlight. Is it made of a plastic (like ABS or PEX) that can degrade in the sun? Or is it more likely an optimal operating temperature range kind of thing, since it's made of black plastic that could overheat? Or could it be an interference thing, too?
