Hi.

After returning from vacation and updating my PS3's firmware I seem to be unable to log in and connect to the PSN. I have accessed the PSN store and purchased things in the past.

My 60 GB PS3 is able to connect to my wireless Buffalo Airstation (current firmware 1.4 - up to date) and view web pages in web browsers. When I test the network connection I receive success on IP and Internet connections, and it fails (timeout) on the PSN network step. When i attempt to connect to the network I receive the message "An error has occurred. You have been signed out of the PLAYSTATION(R)Network. (80710B23)" after a substantial delay.

I have opened the ports suggested by this site on my Wireless router ( * TCP Ports: 80, 443, 5223, and 10070 - 10080* UDP Ports: 3478, 3479, 3658, 10070, and 50100 ) as well as doing a power cycle on the equipment involved (PS3, wireless router, cable modem - all off for 2 minutes, cable modem, then 1 minute later wireless router, then 1 minute later PS3). I do not care to play games online, I simply wish to connect to the marketplace and peruse their wares. This problem occurred after updating to current firmware.

Suggestions?

I changed the MTU to 1492 and during the network test "The connection with the PLAYSTATION(R)Network timed out". Attempting to connect normally results in the same error (80710B23).

Any other suggestions?

Maybe it is down at the moment?

am having the same problem too =(!!!
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...

I have the same problem, i cannot connect to the PSN but can connect to the web browser and update the ps3. I have an up to date d-link router (D-Link DIR-655 Xtreme N Gigabit Router) and a fiber optic internet connection (my provider is NTT).
