(not the perfect place to post this, but there wasn't a forum specifically for the W306AV)
I have a new DHL-W306AV (PowerLine 802.11n extender). It seems to work well, but I can't find a way to turn the LEDs off (for now, it looks like it's going to live in a school hallway, and flashing lights might not be good for its longevity). Any help?
