What Does It Mean When You Cannot Connect to a Steam Network?


Quick Answer

Failure to connect to the Steam network could mean that the user's router is not configured properly or is running in DMZ mode, the firewall is not configured to be compatible with Steam, or that there has been a Steam update that is blocked by the firewall. Additionally, a port required for connecting to Steam could be blocked by some networks, such as those used by schools and universities.

If the problem consistently occurs during certain times, the connection issue could be caused by the Internet service provider blocking the ports needed to connect with the Steam network. Some background applications and programs could be keeping the computer from connecting with Steam, and other potential culprits include adware, spyware, viruses, worms and trojans on the user's computer. In addition, some antivirus and adware programs that include Internet connectivity security elements can block the Steam network. Using a wireless connection rather than a wired one can interfere with the connection, and using a 56K modem, which cannot handle the bandwidth necessary to connect to the Steam network, can also be the cause of connection issues. Disconnecting other machines on the network, turning the modem and router off briefly, changing the rate setting on the modem, and launching Steam using the TCP option may resolve the issue.
