I've been playing TF2 offline practice today and in the middle of the game it says some connection failed or something and the game is over. I am connected via WiFi but I shouldn't even have to be to play offline.
When I was in England I tried to play HL2 (which I've successfully played on my laptop in the past) and it wouldn't let me play it offline. People reckon it should work so I don't know why it didn't, but you might be having the same problem.
So you have to be online to enable offline mode? I guess you gotta plan ahead.I play Steam games (both Win and Mac) only offline and once set up there is no need to connect to play. Here is the word from Steam. Follow the setup and enjoy unlimited offline play.
Offline Mode
QUESTION
What is Steam's Offline Mode and how do I use it?
ANSWER
IMPORTANT:
The Steam client application's files must be updated to allow for the use of Offline Mode. If your game's status is "100% - Ready" but you receive the message "This game cannot be started in Offline Mode" when attempting to play offline, the Steam client application's files need to be updated.
Firewall settings preventing Steam from updating itself are the most common cause for this problem. Please see the Troubleshooting Network Connectivity topic for instructions to configure your network so Steam may update if you encounter any difficulties with Offline Mode.
WHAT IS OFFLINE MODE?
Offline Mode allows you to play games through Steam without reconnecting to the Steam Network every time you wish to play - this is particularly useful if you do not plan on playing over the internet and would prefer not to download new updates for your single-player games.
Please note that you must connect to the Steam Network and test each of the games you would like to use in Offline Mode at least once to set up your account and configure Offline Mode on your machine.
