Hello,
im connected to my wireless network but keep getting an error on every page stating cannot find server

are you sure that your wireless router recives internet connection..
check ip settings & DNS

You're probably connected to your wireless router, but your wireless router doesn't have a connection to the internet. Check the settings in your wireless router and make sure it's actually getting an IP from a host.
