Conectivity problem unable to connect usb datacable/bluetooth L6 mobile to pc for internet in my computer having windows vista stater operating system.

I didnt get pc suit disk along with my phone w270.fromwhere i can get it.

Well, ok first-of-all check if u have installed all the drivers for your motorola phone.They should have been included in the pc-suite disk that u must have got with ur phone.
Drivers tell the computer or software on how to use and communicate with the device.Without that u wont b able to connect ur device with the computer.
Secondly, check the "Device manager" in the control panel in windows and see if the correct drivers have been installed and there is no "?" icon there. "?" icon means that either the device is not working or the drivers have not been properly installed.You might also have to enable the option "Show hidden devices".This option can b enabled from the "view" tab inside the device manager. 
In case "?" icon is there than double click the "?" device and an window would open showing the details of the device.Just insert the phone cd and under the "driver" tab cick "update driver" and just folow the instructions that follows.
Thirdly, if all this does'nt work than check from the manufacturer's site if an update for ur phone's driver(that supports vista) is available or not.Also, get the latest motorola PC-SUITE that supports vista as well.You can also see if any "FIRMWARE" update is available for ur phone."FIRMWARE" adds more functionality to the phone and they r provided from time to time by the respective manufacturers.You can check the motorola site for all these details.
Fourthly, check if ur network operator provide "internet connectivity service" or not.Talk to the customer care executive and if the answer is "yes" than ask him to provide u with the internet settings.These settings r usually sent to the mobile and than they r saved there itself.
Note: that all network operators such as vodaphone,idea etc dont provide internet service everwhere so check with ur operator wheather these services r provided or not.
I hope one of these points should solve ur problem.
