Hi All,
Thanks for replying here with lots of information. I'm glad to see that other people's problems have been solved. Unfortunately for me, after re-installing the correct (new) Facebook firmware, and following the technicians advice that was left to me in a voicemail, I still received an error message that said “Internal Service Error, the central server cannot be reached”.
I spent 2 hours and 45 minutes with a "Level 3" technician named Aaron. We tried several options, and nothing seemed to work. It was pretty noticeable, throughout the entire conversation, that Aaron really didn't know what the DIR-865L Facebook Wifi enabled router was all about. I had to explain the Facebook check-in feature to him, at least three or four times. Our conversation ended, after he had absolutely no idea, and said that he would call me back on Friday the 13th at 3 PM Eastern Standard Time, after he had "done research on the issue". At 3 o'clock, after I had specifically driven an hour to take this phone call, my phone sat silent.
I called D-Link at 3:15 PM and talked to another representative named Carlos. The only problem with that was that for Carlos, who was genuinely trying his best, was extremely unfamiliar with the case, and had to start from square one! Around 4 PM Eastern, my phone rang and it was Aaron! I had missed the call because I was asking Carlos if I should pick it up or not. Aaron called back again, a few minutes later, and I said to him, "I thought you were calling at 3 PM; you're one hour late!”. He went on to say that he had called and I did not answer. I reminded him that he was supposed to call at 3 PM EST (something I had made very clear on Monday's phone call). He really couldn't defend himself, and I was frustrated enough, so I said, "What did you find out!”. After almost a week of research, he said he was going to try to “re-flash the router". I said, "Aaron, you know we did that several times in our last 2 hour and 45 minute phone call on Monday; this is unacceptable”.
I told them I wanted to set up a return, and he proceeded to tell me he could not do that. I said that that was fine, but I had read online that you need an RMA number to do the actual return. He said I did not need one. I argued with him about this and told him to write in the case note that technical support had set up this router for a return and diagnosed it as such. He said he did, and we ended the phone call. He was truly a terrible technical service agent in regards to this second phone meeting.
When the new one comes in, I'm hoping it just WORKS.
Again, the problem is that when the Facebook Wifi feature is enabled, guests can check into our business, but not receive free internet after doing so...
So that is my story!
