Firewall is somehow blocking my entire wi-fi?

[ThisIsMyName]

Randomly after rebooting, two or three notices came up for a utility or application and asked for permission to connect the internet. I chose deny for each of them. (not knowing this would create a problem)

Now, when i try to connect to the internet with firewall on (which i need), it's blocked like this.

And when i went to advanced settings for firewall there were no "blocked applications".

sudo ipfw flush

That will reset all your OS X firewall rules.

A n00b like me must ask, how do I use that code?

Go to your Applications/utility folder and run a terminal, then type the command in the first line of his post.

Everyone was a noob once.

See the above instructions, or just open spotlight (by clicking the magnifying glass at the top right of your screen, or by pressing command + space) and start typing 'Terminal' the icon should look like a little black box. When the terminal opens type the command as I wrote it above.

Come back of it doesn't work

'sudo ipfw flush' didn't work.
Any other suggestions?
