Re: you have lost connection to playstation network, online unavailable!

I noticed one person noted that they had this problem. Here's how I managed to fix mine:

If anyone was suffering from the same issue as I with getting this message every time trying to connect to a game "Lost connection to the Playstation Network, online features will be unavailable" here's how I got mine to work.

Apparently the modem my internet provider gives me also doubles as a router (a rather poor one). Because of how poor it is, I've just always plugged in my own router into it and never bothered to touch anything with the modems built-in router. Apparently a router going through another router like this causes this issue with the game. So to fix it I connected to my modems router manual in the settings, turned it in into a bridge (effectively disabling it as a router) and now I'm finally able to play star wars battlefront online.

So in summary:
- My internet modem was also a router and I had plugged in my own router into it.
- This caused the issue with me constantly losing connection to the PS Network with this game and this game only.
- I effectively disabled my modems built-in router by making it a bridge, and am now able to play this game using my own router.

This specific link below was the guide I used to turn my modem into a bridge. I'm sure you're ISP has one on their website: http://www.rogers.com/web/support/internet/home-networking/247?setLanguage=en

Hope everyone with this issue can get it to work.

Cheers
