Sony Vaio laptop having problems connecting to the internet, PLEASE HELP!

Hi there, I have a Sony Vaio VGN-NS110E laptop computer running on Windows Vista Home SP1, and I felt like reformatting it, so I restarted the computer and went to the Vaio recovery center and reformated it from there (I wasn't aware that simply having Vaio installed on my computer could do this and self-reformat without a CD & Cdkey... or am I wrong here?) Anyways I reformatted it now but now there is a major Wireless problem. The previous owner told me this compute had a wireless problem initially so I was forced to always use a wireless adapter (TP-Link, 150mbps) but now my computer cannot even find a wireless connection at ALL. Usually I've had problems in the past where it could not connect, but now I can not even detect a connection! I installed the Unknown Device Driver and tried to detect anything but there are no red flags (meaning all the drivers are installed properly,?) so am completely CLUELESS on what to do now... Where do I start? Have I given insufficient information? I need to get started on a paper due very soon so I am praying that somebody can help me asap. Thank you so much!



Please help!

 

So you're saying about internal or external wireless adapter?
If it is internal, there may be a problem with your wireless minipcie adapter or its contact to slot issue.
If it is external, first check usb ports to make sure they are all working properly.
