My sisters hp notebook has been unable to connect to the internet for a few days now. She said she hasnt added any software or made any major changes but she doesnt really know as much as I do when it comes to the softwares I put on her computer for protection such as Spybot and the Comodo Firewall. She told me she has denied request from both applications but Im not sure thats the problem because I uninstalled both and still cannot get a web page to open. I thought it could be the cheap USB Network adapter she was using because it was very flimsy and had broke open a while ago (its now held together by clear masking tape lol) but I installed the drivers for a linksys adapter (WPC11 ver4) she had and used it and I still cant get any results. I can even get a connection to our wireless network sometimes but I still cant view any pages when I open Internet Explorer. Can anybody let me know if this is a hardware, software, malware issue because this is the most trouble Ive ever had with a pc.
