I am not so sure if it is a general problem or just a DLink problem.

I just activated my own access point and it worked there. The only
problem is that it also works with DLink but only randomly. So, it
still could have been that I was just always lucky when connecting to
the ProLink access point I have.

As the DLink is not mine, I am not even able to access its
administration interface.

Can I suggest to wait a bit to get more feedback to see if it is a
general problem or a problem only linked to one manufacturer?
