Network configuration

Improving network access

Sometimes the problem does not lie on the internet but with the service providers that have blocked the operation of Steam traffic for a particular time.

This is because the traffic generated by Stream is quite heavy and lowers the profit margin of the internet service providers. 

A common method to avoid this is using a VPN, as it encrypts the streaming traffic and lets the bin pass through a different route.

However, the VPN has to be selected wisely in the case of Mac, as many of them create a lag between the system and the server.
