Yesterday my laptop, a toshiba with windows Xp, would not let me browse the internet. It keeps saying webpage cannot be displayed. The wireless connection signal is strong and it cant be the wireless as i have two more computers that connect to the same wireless network perfectly. It is a wireless signal that we are picking up from someone that lives above us and we have the password etc. It has worked for months now and this is the first time i've experienced a problem. I already tried to restart the internet , and i've restored my pc to a few days ago but nothing seems to work. It's really frustrating so if somone could help me i would be really grateful.

Thank You,
Nayome
