In Software Center I found only one wimax driver "madwimax 160-0ubuntu1" which is already installed (based on Samsung CMC-730 chip). I can only uninstall it. But if I will uninstall it I can not install it from Software Center because I have only Wimax internet.
Well stopping NetworkManager solves the problem of deb files installation, but when it is running again, the problem recurs (after you reboot computer).
Thus, the temporary solution for installation deb files can be solved by switching off NetworkManager or installing through the command line.
