Another problem might be with your Internet Provider's DNS server (the thing that makes an address, ie:
www.marioboards.com, point to it's IP address) is shoddy, which you can change. I personally use Google's one and that seems to be the most recommended. You can read a bit about it
here if you're interested.
To configure that, go to your Control Panel
- Win7: Start->Settings(I think?)->Control Panel
- Win8: Right click the Windows logo->Control Panel
- Win10: Something like the above (prob)
Click on 'Network and Internet'
In the Search bar, type in 'View Network Connections' and click the result when it pops up
You'll probably see a result like 'Ethernet', 'WiFi', etc. Right click the one you're connected to (or do it for all of them)
This is where it gets a bit tricky. In the menu there will be a list of things under the message, 'This connection uses the following items.' From here, find something that says something like:
- Internet Protocol (IP) / Internet Protocol Version 4 (IPv4)
- Internet Protocol Version 6 / IPv6
You may have both, in which case, you should do this for both of them
If you have IP / IPv4 (you most likely do), click it and click 'Properties'
Click 'Use the following DNS server addresses'
Type in the following:
First entry: 8.8.8.8
Second entry: 8.8.4.4
Click 'Ok' to accept and go back
After you've gone back, click 'Close' to apply the changes
If you have IPv6, click it and click 'Properties'
Click 'Use the following DNS server addresses'
Type in the following:
First entry: 2001:4860:4860::8888
Second entry: 2001:4860:4860::8844
Click 'Ok' to accept and go back
After you've gone back, click 'Close' to apply the changes
