I am having qtel mosaic + . Over the wireless i use it to connect to internet, but always when i connect it says ANOTHER DEVICE IS USING YOUR IP ADDRESS.mnf.qqq.c.qwe., even though my other PCs are shut out. Why does it so cautions me and is it that my neighbours are without my permission using my wireless. Is it not dangerous for me and illegal for the person doing so.
I would suggest to you to use a password protected wireless connection so that no "neighbor" can use it.
Maybe there are rules against it but so far whenever a wireless is open (not password protected) people tend to use it freely and without even asking if they can.
Just set up a strong pasword and block anyone from using your connection without permission (remember you are the one paying while others are enjoying)
Regards!!
