As a test, can you move close enough to use a wire? Maybe there's a TV within reach of your router? What you're describing sounds like a connection issue and they are far more likely to happen over wireless than wired. Even if it's normally fine, wireless is very easy to interfere with. If you can't do that, I'd suggest going through the connection troubleshooting steps here. HUT Rush and Squad Battles are single player, but they're not offline since HUT requires an online connection. So, they are going to be susceptible to the quality of your connection.
