After coming back from a two day vacation I turned on my MBP to realize the date abd is incorrect. I connected to the internet and a pop up came up asking to accept or deny, i hastily clicked deny. I think that is the reason why I now cannot use the wifi connection. My airport is on and it shows full bars however I cannot access any websites. My only option for internet is to use an ethernet cable.
I searched and searched but I have not found a solution yet.
I went through system preferences, reset the router, all of which did not work.
Any tips? Thanks in advance!

you dont have any proxies turned on like a socks proxy right
 
Have you checked the advanced settings of Firewall in the Security prefpane for anything that shouldn't be blocked?


Also another thing you might try is this:
open network prefs, highlight Airport on the lefthand side and click the minus sign to delete it. Then apply. Then hit the plus sign and re-add Airport and set it back up.

this^^, also i just thought of this did you try a different browser. if it works with other browsers reset the one you want to use
 
Thanks but none of these solutions worked. :/
any others? In the preferences my ethernet is green and my wifi is red.
 
Try turning off the application firewall, deleting com.apple.alf.plist (in /Library/Preferences/), and restarting the machine.

You will have to reconfigure your firewall settings but I find this solves issues with default services prompting for firewall exceptions and network issues.
 
You actually have to delete two plist files.

/Library/Preferences/com.apple.alf.plist
/user/libexec/ApplicationFirewall/com.apple.alf.plist

This post will show you how to find these files with Finder

I was successful at finding and deleting the files. Restarted, however wifi is still not working.
I tested it at a family member's house and the issue is within my own laptop.
 
did you take your laptop on the vacation and use it? sounds like you might have residual default gateway settings in there or something from another network
