Hi All,I have similar problem. so I 'm posting in the same thread. I also want to connect both my desktop and laptop to the internet at a time. I 'm able to connect to internet using LAN port directly to the internet(without entering my userid &password). My problem is I 'm not able to connect to the internet with USB port. I tried to follow the steps given in CD provided by BSNL. but I couldn't find any driver(My modem is UT300R2U 2.2) In the DSL router page of the modem, it is showing message as 'USB conenction failed'. Can any one suggest me what I should do to connect to internet using USB port. if any driver to be installed, please someone provide me the link to download. please do needful. Regards,Hari
