The mystery of the blue light

A couple of months ago I purchased a router/wifi accesspoint which has been running smoothly, as expected, until a few weeks ago. After I installed an extra electrical outlet and some cable channels for the power and ethernet cables it suddenly stopped working. After a frustrating evening where I at first thought I damaged some of the cables I got it working again. Until yesterday.

This time the diagnoses was simple. I couldn’t figure out how to fix it and the D-Link support desk (which was very easy to reach and provided excellent service, to my surprise) told me it was broken and I should return it to the shop where I bought it. Thats bad, but not at all difficult or complicated. After all, it’s just the wifi accesspoint that is broken so we can still hook up to the internet with the ethernet cables we have in most rooms (I installed those for gigabit access to the local fileserver).

So what about the mystery then? Well, there is a button on the side of the device which is not mentioned in the manual and when I press it it lights up in blue for a while. No idea what it does, so I just ignored it. Until today, because all the device does now is lighting up that blue button. No other lights, no other activity. A search on the internet for “dir 615 blue light” brought me to some forums where I learned that it was for WPS and that it is mentioned once in version 2.20 of the manual. Well then, another mystery solved.

Overall I was impressed with the support desk. There were no wainting lines, they promised to call me back and did withing a few hours, and, as opposed to the technical support mentioned on this forum the technical guy I got on the phone was fully capable to explain to me what this button was for. More points scored for D-Link’s support desk in the Netherlands.
