Hi to all!. I recently bought new computer and reinstalled windows, and i have a lot of issues that i wanted to fix, but i have no idea. I was using windows 10, but i've installed windows 7 and i think that there are some issues with brandmauer. I can't use postgresql port because it's also not working and many ports are not working with other computers from the internet. May be, it is an issue with modem, but I'm not sure. So what is your opinion?
