Disconnected from EA Online (1)

[drfunhk]

Pretty much every time I play BF3 online I get disconnected after 20~minutes and get a message saying "Disconnected from EA Online ".

I have my firewall turned off if that's any help. So, how do I fix this?

Hello drfunhk, is your Punkbuster up-to-date and have you forwarded the required ports?

I have the same problem.  My PB is up to date.  How about listing the ports or linking to them?
