I'm having a problem with my dsl connection (was my fault that it doesn't work). I launched a program (that launched cmd and did something with ipconfig), and now, the internet doesn't work. The modem was reset, unplugged, etc. and it still doesn't work. I compared my ipconfig with my cousin's ipconfig (we use the same connection): everything is filled in (connection specific DNS suffix, ip address, subnet mask and default gateway), while I'm missing connection specific DNS suffix and default gateway. The ip address is also changed (it's 10.0.0.1), while my cousin's is 192 something. Edit: I copied all of the info from my cousin's ipconfig and entered it as my own. I reset the modem, and it shows me as connected (when I go to the modem's ip), but I still can't use the internet. Edit: When I set my TCP/IP properties to obtain an ip automatically, the ip address and subnet mask come up as 0, while the DNS suffix and the default gateway stay empty. My cousin's properties are also set to obtain an address automatically, but ipconfig shows the connection specific DNS suffix, ip address, subnet mask and default gateway. Edit: After waiting a couple of minutes, the internet works again. Are there any ways to solve this problem, in case this happens again?
