Default Gateway Problem

[kodiedawg]

Ok so I used to play this game age of empires 2, and it wouldnt let me connect so i used DMZ whenever i wanted to play, but i gave up on that game and forgot i had DMZ left on, and so ive went and played WoW and my account got hacked, and after this has happened i cannot access default gateway as i am trying to disable DMZ, i have ran alot of scans on my computer cant find anything.. any ideas?
thankyou

How are you connected to the internet, is it a wired connection or wireless connection? Try to right click on your network adapter and choose properties. Next double click on TCP/IP. Now inside here you should make sure their is a black dot next to "Obtain an IP address automatically". You should also set "Obtain DNS server address automatically".
