I am having trouble connecting to my office network using this wireless card, UM175, and connecting with a VPN. I have the VPN set up the same as many other computers connecting to our server. Currently when I start VZAccess, I can access the internet and everything works fine. When I start my VPN to connect to my office server, it takes multiple tries with error 691 being returned. After two or three tries it connects. I can ping my computer from the server. I can ping my router and my server from my notebook with the UM175. However, I cannot do anything with the server. I cannot access the internet, access files from the server, or access any software on the server. I contacted IT and our administrators and they tested the system and VPN and state that there is a problem with the modem UM175. Is there some setting that I must set to make this work correctly. This is an urgent matter and must be working, or I will have to purchase another type of modem.
