a)What was the fix for your problem with the internet?
Maybe you can post your soloution here, so that the next person don't need to create a new thread and can try to
use your way to fix it.
b)The most router have a NAT "port forwarding" feature. If people can't connect to you should open these ports:
1. Port UDP 6112
2. Port UDP 9100
3. Port UDP 9101
4. Port UDP 30260
5. Port UDP 30275
The problem is that it allows people connect to you, if you have a dude you want to connect to and haven't open
these ports you will not be able to connect to this person.
Here is a small instruction for "Hot to open ports" for your router:
