Unable to connect to the Steam network

Steam worked fine yesterday, but then I start it today, and it comes up with a updating loading bar that freezes at zero, then comes up with an error:

Quote:
Unable to connect to the Steam network, 'Offline Mode' is unavailable because there is no Steam login information stored on this computer. You will not be able to use Steam until you can connect to the Steam network again.
So far I have:
-Restarted my computer
-Deleted ClientRegistry.blob
-Unchecked 'Read Only' on the Steam folder
-Created a network bridge for both of my network adapters

I had this problem previously when I tried to install Steam. I fixed it by creating a network bridge. I try that this time however, and it doesn't work.

Please help. Thanks.

If you are certain that your internet connection is fine and nothing that may potentially interfere with Steam has been installed, updated or is running:
Steam KB/FAQ: Programs Which May Interfere with Steam
Then replace files and folders located under the "\...\Steam\" path:
  1. Exit the Steam client application.

  2. Browse to the Steam installation folder ("C:\Program Files\Steam" by default).

  3. Delete all of the files and folders except the "SteamApps" folder and "Steam.exe" file.
    (Optionally, you can also choose to retain the "Userdata" folder to preserve settings.)
  4. Under the "Steamapps" folder, delete the file "winui.gcf"

  5. Reboot computer and <Right-Click> "Steam.exe" and select [Run As Administrator], log into your account as prompted.

  6. Steam will re-download all the missing deleted files and then start up.

I did everything you said and the same thing happens, except I get a new error:

Same error I guess it's probably a network problem then?

I would think so. Something on your PC or net connection has changed since the other day when Steam worked fine.

Did you check that list linked earlier for any programs that could be causing an issue? Specifically Anti-Virus, Firewall, etc?

Check if your ISP is on this list:
Steam KB/FAQ: Known Issues with Internet Service Providers (ISPs)
Check that the required ports for Steam are allowed through your Router and Firewall:
Steam KB/FAQ: Required Ports to allow for Steam

I think I'll have to open some ports on my router. Thanks for the help anyway.

ran the Firebind Steam Port Tester - got this result:
TCP Result: SUCCESS
Testing TCP Port: done
TCP Passed: 27014-27050
TCP Failed: none

UDP Result:
Testing UDP Port: 27018.........
UDP Passed:
UDP Failed: 1500,3005,3101,3478,4379-4380,27000-27017

Dont think I can edit the ports as i'm on a university network (but one that according to the forum list should be ok)

The problem is resolved

My Router Firewall was set to 'Medium' instead of 'Low' aggressiveness.

I changed the settings for more security but it seams this program can't connect on Medium.

I'll keep my Router Firewall settings to Low and allow Steam to connect with its ports.

I to am having the exact same problem - just started today. Absolutely nothing has changed in my networking config, same router as ever, same anti-virus software on my computer. The ONLY difference, is that all of a sudden I can't log in it says that I am offline.... which I am not as I can reach this page and make this post.

Speed tests confirm my connection is at normal performance levels.

Whats going on?
