hi everyone

today i installed ubuntu 10.10 (for the first time) . my modem was working fine with lan cable . then i used additional driver to install my vga card (ati 5770) driver . after download and installing driver , ubuntu asked me to restart so the driver can be activated . after i restarted my pc the lan led of adsl modem turned off and ubuntu couldent find the modem . even in windows 7 i tried to connect the modem but the lan led did not turn on ! really confiused !


any comment ?


thank you very much.

It seems the problem in modem, check power supply of modem, otherwise it should work for one of the OS.
