I am having a similar issue with connection termination with a USB Modem UM175. I am only trying to get my modem to stay connected on my MacBook for a continuous amount of time longer than 5 mins. After a few mins I get an error message saying, "The connection was terminated by a remote site. Please try again."
Any help? Mac people nor Verizon people can seem to figure out what it is. I am so fed up but have limited options in the area.
Thank you so much!
Get a wireless router from CradlePoint I got mine from here http://www.3gstore.com/cradlepoint YOU weill get tech support for your gaming plus they have an evdo gaming guide, with a router you will only need to setup the wireless connection once and any user on any computer, xbox, playstation 3, or Nintendo Wii can connect via wifi or ethernet. its so easy even a cavemen can do it.
Order from 3gstore > Get the router and turn it on > Connect your verizon card to the rotuer > 15 seconds your connected just connect to the wifi like you would at a coffe shop.
