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.
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...
