I have been playing this game since closed beta. No problems except the once in a while bugs, however everything messed up when I changed my isp provider.
Suddely I could not run MWO anymore, I would always the the error "No internet connection detected" and the launcher would crash. I don't even get to the log in screen.
Tried the uninstall/reinstall route, but I found that now I can't even reinstall the game now as I get the same error "No internet connection detected" and it will crash out.
Nothing has changed on my pc except my isp provider and than I'm using a router now. However, I did once try plugging in my pc directly to the modem, but it didn't change anything.
I hope the more tech-savvy people here could give me some ideas, it has been almost a month since I was last able to play and am sorely missing the game and my guild buddies.
By the way, this only happens to MWO, I am able to surf, email, download, play other mmo's so 100% am connected to the internet, except for MWO.
Here's a sample of what I have been saying
