Windows 7 and HUAWEI E1550 USB Modem

A little background

For some, access to the Internet is an integral part of life, for some it is a must, and for someone a privilege. In my case, this is a privilege ... In our provincial town in the south-east of the Krasnodar Territory, the situation is at a very deplorable level (the local UTK monopolist, which provides access to the Internet using ADSL technology and several small offices that work with several fiber optic areas), moreover the prices and quality of services leave much to be desired ... And fate decreed that there was no way to use the services of any of these offices. Due to duty, and just for the soul, the Internet is at least some, but needed.

I decided to purchase the MTS Connect package, which comes with a HUAWEI E 1550 USB modem and a SIM card with a more or less favorable rate for surfing. At the customer service center, I carefully studied the box of this miracle, which indicated in the section "system requirements" the presence of a standard USB interface, OS Windows XP / Vista, Mac OS X 10.4 / 10.5. The first question that I had is whether this piece of hardware works with Windows 7 because I have been its user since the release of the first beta. The center employee categorically replied “No, it won’t work with Windows 7,



When I got home with absolute certainty, I decided to connect the modem to the desktop on which the same Windows 7 build is installed, only x64. Almost immediately, I received a notification that the driver installation failed. I can’t say that I was disappointed that I made a useless purchase - from my own experience I was convinced that Windows 7 works and the only difference is in the bit depth of the OS. The first thing that came to mind was the search for the appropriate driver on the network, but 2 hours of hard searching did not lead to a solution to the problem. Partly ... Having connected the modem to the laptop, I climbed into the device manager to analyze the situation. The modem is defined as a regular CD-drive, on which there are drivers and software for accessing the Internet (MTS Connect). Googling on the issue of determining the optical drive of Windows OS came across an article Help and support for Windows, which examined one of the solutions to the problem.

Small solution to small difficulties

3. Remove the parameters UpperFilters and LowerFilters from it
4. Reboot car
5. Problem solved
Note "If the LowerFilters parameter is absent, this article, unfortunately, will not be able to help anything anymore" caught up with some anguish :) but fortunately this did not apply to my case. After rebooting, the modem successfully detected and earned.
