Call of duty 4 problems connecting!!!

Hi im lvl 55 no prestige (silentsnowman is my psn id). I have a working connection i have done a test and have a working connection. I also have gone in the playstation store. When i go to play online i go into the multiplayer screen and it says loading game settings ( the area where you choose the game type) normally it takes like a second but i let it sit for exactly 31 minutes and it did not work i did that an hour ago after updating. This started 2 days ago and i examined the disk under the light, cleaned it a total of 3 times and it still wont work. I can play single player but multiplayer wont work. Even split screen wont work right it will stop in the middle of loading. I talked to someone i know and he siad it happened to him once. Is it just us or do alot of people have this problem? Please can someone help me i can't play and would like to, any help is greatly appreciated.-Thanks

I may have sorted it...

I've been having the same problem occasionally, all I've been doing recently is rebooting the modem, reconnecting and BAM, it works....
I've got one of Telstra's **** Speedstream 6520's and this works EVERY time, good luck bro hope this fixes the problem.
