Except for rack mounted routers, they use passive cooling. Just an
undersized heatsink trying to dissipate heated air through tiny holes in
the case. That is why they recommend against stacking their units
despite they even provide case recesses to allow stacking. Over time,
and with no active cooling (e.g., fan), the dust collects on the
heatsink (and other PCB components) which is a thermal insulator. They
die after 2-5 years simply because their brains got cooked. Consumer
grade Dlinks last around 2-3 years. Linksys lasts longer but I've had
to replace those, too. Look at LCD TVs or monitors and routers. The
monitors are vertically oriented, have more dead space inside, and the
heated air gets to rise and escape through larger vents. In contrast,
routers have their PCB horizontally oriented, the dead space is maybe an
inch high, if that, and the air cannot get through those tiny case holes
(so so flow is established by the movement of heated air out the top
bringing in cool air at the bottom). If you want better air flow, you
have to drill out the case holes in the router to enlarge them and also
be sure to include holes at the bottom so outside air can be drawn but
assumes the air can get around the PCB since the case probably comes
right up to the PCB.
Having an air conditioned room only procrastinates death from bad air
flow design. No, I do not operate my house rooms at the frigid
temperatures of a computer room; however, there is enough air
conditioning so temps and humidity are within a range that is
comfortable for me. In comparison, my computers never die due to
overheating because I design them with decent air flow plus they are
monitored unlike routers that bake away without any alert.
Typically you'll notice flaky connections. You think there is a problem
with your ISP but that's not it since a direct connection from computer
to modem (bypassing the router) works just fine. The flaky outages
start increasing in occurence and duration until one day you'll be damn
lucky to get any connection.
