Game disconnected: you were kicked by PunkBuster. Stated reason: PunkBuster kicked player (for 0 minutes) ... No Packet Flow


*This is the tutorial to fix no packet flow*

There is 4 easy things you need to do to fix this problem.

1. Allow all punkbuster files from you're firewall (Both of them, Windows' and you're internet security's firewall) and check that PunkBusterA and B (if you have it) are working, from services.

2. Update PunkBuster for Battlefield 3 (delete old folders of PB before updating it)

3. Update your modem/router drivers (very important!!) If you dont know how, try this link
