This driver didn't increase connection speed for me, however it increased download speed. It definitely improved my modem performance. Please feel free to email me firstname.lastname@example.org for further info. This was used for AZT Mr2800 with a software version supplied by smartlink. Hardware version is SIL-22(sec)on ICH. I found that the driver was didnt install and would not install until i put my windows 98 disc in my CD ROM. If you have trouble try the same thing as I tried everything theorectially possible but it would not install until I put the Windows 98 disc in CD ROM DRIVE. You may be luckier than I was. IT now works like a dream!
