We can then start debugging from that position. > 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? Erich
