I have an ACER Aspire 7110 laptop with the Intel 945 video chipset. I am running Vista Home Premium OS. When I run the AT&T Communication Manager for the Sierra Wireless Aircard 875 the video mode goes to 640 x 480 8 bit video mode. When I close the application the video goes back to normal. I have used the 6.2 and the latest 6.6 version of the program with the same results. I changed the video driver to the latest from acer and that made the display quality even worse. I have talked to AT&T support and they had no answers. There has to be a video setting in the registry that can be changed for this program, but I can't find it. Any suggestions would be greatly appreciated. Thanks!
