Hi nk5514 and welcome to the eForum
Thanks for your post here. I'm sorry to hear that you are having problems with this.
Has this ever worked for you?
What colour light is showing on your modem when plugged in?
Do you have another PC that you could try the modem in?
What operating system are you running?
Please let me know and we'll be more than happy to help you further
Thanks
Wayne
