Большинство винмодемов не поддерживаются Ubuntu, но драйвера для работы таких модемов можно найти. Сначала вам необходимо определить, на каком чипсете построен ваш винмодем.
Read this file; it should list what modem chipset you have. Once you are aware of the chipset you have, see http://www.linmodems.org/ and follow the directions for your modem. More infomation can be found at SettingUpModems on the Ubuntu Wiki.
All PPPOE and router-style ADSL modems (that use ethernet for the connections) are supported by Ubuntu, and some USB ADSL modems are supported too. For router-style ADSL modems, just connect it, configure the modem per your ISP's instructions, and configure networking in Ubuntu. For information on PPPOE modems see this guide on the Ubuntu Wiki.
