hi.i desperately need your help .3 weeks ago i was able to connect to internet on my ps3 and play online and download demos and everything.then the internet service of the place where i live in KARACHI,PAKISTAN changed.i live in a flat type of housing where there are 4 buildings of 6 floor each with a single network service.in this new service i am not able to connect to the net.2 error come ps3 disconnected from media server and connection to server timed out.i have no clue what to do and also there is no router as there is no permission to visit it as it manages all the flats.my pc works finebut iam not able to connect with my ps3.someonetold me that it may be a problem with my service or it doesnt support ps3 so i brought a different sevice named wateen telecom from my friend.he brought a motorolla router and a cable and a power supply adapter but i still wasnt able to connect as the same error came but the disconnected from media server didnt came.when i connect on the pc both the watteen and my current service ask for a login id and password of some kind ,could it have something to do with it.i am fed up of searching on google and trying again and again with no success.please help.

thanks for the advice but could you explain me that how would the router handle the log in process and also how to open up ports

ok suppose i purchase my own router...then can i operate my current net service by plugging in my ethernet wire to the router then to my pc or ps3?
"in my current service ps3 dosent works online".
and once i connected my ps3 with the motrola modem or router at my friends house and it worked fine..so i tried to do it at my home but it didnt work. and let me tell u only one out of 3 signal were comming.i think so tats the prob!?

i have also decided to buy that wateen service from my friend but i am confused because the only reason i want to purchase it because it would connect my ps3 online but currently it is not.actually i dont know how to login using the wateen on my ps3 but on pc when i open firefox or internet explorer they ask for user name and password.from where can i input the network user name and password of the wateen in my ps3?
i agree with you that the current service doesnt support the ps3 as my sevice provider said that there network have some sort of high security which may be preventing the ps3 from connecting?nonetheless i am gonna get that wateen.

i wll get another service hopefully but if my current service works that would be great.today i tried to enter the user name and password in the PPPoE section and it said attempt to obtain IP adress timed out.Is it possible for me to connect through PPPoE.
