Re: call of duty 4 and a router

Usually you can only put on of the connections into dmz I would double check these settings and make sure or just use the router in switch mode.

I try to send my friend a game invite and when he tries to join it said session unable to join

Do a connection test and make sure that your NAT Type is 2, any other number will cause issues with games with friends. If its any number than 2 do a factory reset on your modem/router and if that doesn't do it then go into your modem/router configuration and set your PS3 as a DMZ host and that should take care of the problem.

Having trouble joining group on Call of Duty MW2 wont let me join with my friends

Usually, this is due to your friends inviting you then they enter a game so you can't join their lobby. Try talking to your friend at the same time and make sure they dont enter a game so you can get to their lobby once they've invited you.

Every time my freinds invite me to a game in call of duty world at war it say the games session is no longer available what can i do to fix that

Try turning off your console and turning it back on- that's what I did. Are you using a wireless adapter? If so, then it may have trouble connecting. Try moving it to an area closer to your router. Also, the cod5 servers **** lol, so it may clear up in time. If you haven't checked already, make sure his game isn't full.

My ps3 wont connect to my friends

The problem is your internet is not good enough to host or join their game. There is probably some type of connection problem or their game is full. Hope this helps.

Cant invite some friends

If you have a Wirless connection, try resetting your router. This helps alot and is normally the solution to your problem. If not then it could be that your playstation console is to far away from your router. Try moving it closer to the router to boost the signal and stop the signal from been fragmented.

'Invitation' on Call Of Duty

There are lots of reasons for this, you don't match the ranking requirements, the room is full, network or host error. Nothing to worry about, just try another room.

Multiple (3) ps3 and call of duty 4 in 1 house

On the Ps3 that isn't working, go into the settings and see if there is something under it that is prevent invitations or friend requests. It will probably be under parental controls or network settings. If someone else hosts the game can that Ps3 join. Also try and get the messed up one connected by ethernet cable and not wireless, it may be cutting out as there are 3 ps3's and probably multiple computers hogging the signal.
