Hi, before i start.. let me tell you about my networking specifications.

Connection : Internet: ADSL Dial up MODEM , 512 kbit connection (download rate around 60kb/s) . Note : this is not a router. and i input my username and password for connecting to the net.

-PS3 to Pc : by LAN cable ofcourse, i share the the internet with the ps3 by connecting it to the pc and make an option to enable sharing.(that doesnt matter for now)
PC: windows xp service pack 3



I used to have no problems at all with UPnp connection and playing online.... just had a little problem before with disconnections , till i figured out from forums that disabling upnp will do something.. and it worked. so right now i got media sharing disabled and.. media sharing in windows media player disabled. I connect with the DNS which is from opendns.com. But now.. these days.. am having a new problem... which is not DNS related. I can connect to the internet successfully on my ps3 but not the playstation network.. i think that happened when i did some playing with the mtu in pc. ( and i dun even know wth is an mtu) . please... any solutions? i havent played metal gear online for soo long! thank you.

*****************

extra information:

i live in the UAE and my network settings on ps3 are : ip address automatic, MTU automatic,DNS server (the one from open dns.com) , upnp disabled, wired connection and..no dhcp hostname...wat else?
OH AND iam 100% sure this doesnt have to do anything with my firewall! i use kaspersky firewall and not windows firewall...

What are the exact makes and models of the external devices you use for Internet?
You will need to open ports 80,443,5223,3478-3479,3658 to connect to the Playstation Network.

open ports..?? dude i mentioned.. ITS NOT A ROUTER!!!!

[Hambuga]

its a cable modem connection as they say

Maybe if you specified the EXACT make/model of your modem we could be more specific.

Truthfully, I'd consider a broadband router to connect all of this stuff directly, it would simplify the complexity of using your computer to interface to the PS3.

its aztech ADSL USB modem DSL 206U

[Jason08]

That modem could also work as a router. Go to start>run>cmd. Type ipconfig, and take note of the IP address that is listed directly above subnet mask. Then go to www.portforward.com and check the external IP address. Are the 2 the same or different?

[Hambuga]

they are differennt

[JohnWill]

Hmm... The modem he posted is a plain modem, don't know where you get the idea it has routing capability.

I'd still recommend a DSL modem/router and solve all these issues the right way. I don't like USB for networking anyway, and trying to share the connection is just adding more complication and reliability issues.

[Hambuga]

dude.. its fine now... i solved my problem.. it had something to do with MTU.. i checked my MTU in my pc... and then manually set in on my ps3..

[Jason08]

Interesting. The modem is probably in bridge mode, because if directly connected to it your IP is different from the website, then often either it is in routing mode, you have a proxy, or your ISP is NATTing you.

But anyway, glad it's solved.
