Playing call of duty 4 online

Crowded servers lead to this issue, try connecting at a different time.

Try doing a factory reset on the modem/router, also do a connection test on your PS3 and make sure that your NAT TYPE is 2 anything other than that will give you problems playing online. Let me know if you need help with getting your PS3 to a NAT TYPE 2.

Hi,

can you go to network settings in your ps3 then test internet connection. If it says UPNP unavailable then you need to enable it in your router or upgrade router firmware if router shows UPNP as enabled.

Thanks.

Upgrade to the newest firmware, since 3.0 had some freezing issues with some games, if your internet connection is slow it would also cause it to freeze up

Most likely you are behind a Firewall / or preset Router Settings. If this is the PS3 version of the game, most likely its the router. Double check with the specs for Port forwarding online, and make sure the ports are open to allow you to play.

-GamePorts required open / Notes Call of Duty 3Source & Destination port 3074 allow outbound + inbound on UDP and TCP. -

CoD in most instances uses the same ports for all there games. This is the first thing I found after looking through Google search. Hope it helps.

Welcome to the servers at call of duty :)
I've got a ps3 and call of duty 4+5, half the fun of the game is playing with a mate and I've had exactly the same problem as you. It just seems to be about trial and error sometimes, have tried connecting like you for over an hour before and then on other days it just connects wth my mate straight away.
Sometimes it helps to join a game(so you can see and hear other players) then invite your mate, if he/she to reply to your invite is quick sometimes you can get in that way.
The only other bit of advice is to try different times of the day as the load on the servers does change throughout the day, apart from that it really is an issue with activision and for me the playstation network
hope it gets better for you

Playstation3 needs reliable, stable, and quite fast internet connection. Check with your internet service provider to get better speeds and this will solve your online gaming problems

if you are using a wireless connection the signal may be to weak. if not you can try deleting your game and save data. you will lose any single player saves you will also have to re download any map packs you purchased. the game should also do an update when you load again after deleting the game and save.

They are making updates to the servers.
Please be patient as they are trying to get the servers up and running.

And yes, some people can still connect to the servers while others can't. This is normal during updates. Just wait for about a week and this will go away. If there's still a problem, call Activision and tell them of the problem.

do a hard reset and try the same
