Recently been noticing the LEDs on my TP-Link routers turning very bright then burning out. Also happened on my modem. Usually the INTERNET light that's always on burns out. The other blinky lights seem fine. Since my current openwrt router wasn't exactly cheap, and I'd rather nothing on it break, I want to know if there's a way to prevent this. Like scheduling down time for the LEDs and how long it should be to help prevent burnout? seconds or minutes?
