Network Errors: Two psp's on the same wifi

[Khabarakh]

What ISP do you use? Is it DSL? I ask those questions because if you have crappy DSL then that is your problem. You mentioned playing solo would give you errors every so often. What your most likely running into is not enough bandwidth for both systems, let alone just enough for one.

I use cable at my house, but at my wife's parents they have DSL running at speeds of 256Kb/s mind you dial up is 56Kb/s so your not that much better off. As it stands I wasn't able to play PSP2 infrastructure mode very well. It lagged for me and those I did missions with noticed immense lag on their end as well, compared to when I hunt with them on my Cable connection, its as smooth as can be.

Unfortunately this game requires a lot of bandwidth (given the size of the game itself... and the online functions.) Unlike PSO back in the day on the GCN using dial up was just fine... Its all in the programming.

Yeah, i have a 6mb/s connection. Its great - download speeds are usually around 600kb/s. I don't think thats the problem. It's charter - they have monthly bandwidth limits - possibly could have something to do with it?

My roommate(Autec) and I play on the same router all the time. No problems. We also have 3 laptops, a PS3, and Xbox 360 connecting to it also...no problems.

People have a misconception that a slow connection is bad for playing, and a fast connection is good. Simple reality is you could probably play this on dial up *IF* it was a solid lag free connection.

What matters more than how fast you can download PSO Porn XXX v3, is your connection to the server.

Simple concept -

Your device sends a 0 to the server, a good connection will get it there quickly and the server will respond with a 1. You keep this process going and you are playing online consistently.

If your device sends a 0 to the server, and it takes 2 seconds to get to the server, and then the server sends a message back and it takes another 2 seconds, you have a 4 second lag. Generally this will eventually time you out and sever the connection.

Also keep in mind that a laptop working fine on wifi loading webpages isn't a good indication of connection strength as you don't need realtime data transfer to occur to have the webpage to load in 99.9% of the cases.

Humorously enough one of the best testbeds for non technical people is WoW. Just log into game and look at your ping.

I have cable, and use a usb wifi adapter to connect online. I was able to play through at least 7 missions with my friend on the same connection with both our psps (I was completing cmode with the import jp version).

If you're trying to play the same game on two different machines on your local network, it's a strong possibility that your gateway router's NAT (network address translation) isn't up to the job, at least without some additional configuration.

Most home Internet connections are behind a box which takes one routable address (that anyone on the Internet can reach) and translates connections to many different non-routable addresses (also called RFC1918 or local-use addresses - think 192.168 or 172.16).

The router has to keep track of which ports go to which systems internally. Sometimes if multiple systems are trying to use the same ports the router either can't keep up or doesn't have a way to distinguish between the sessions.

I haven't looked yet to see what ports the PSN stuff for PSP2 is using, but if it's on the net somewhere, I'd look for the port numbers and check your router for something called "port triggering." It's a setting that tells your router to open certain things when it sees certain ports in use. That's one possibility.

With enough devices connected by wireless at once, It might not have enough "slots" left for the other. Or it could be the 10000000x things people above me suggested. :l

This may be a shot in the dark, but do we know if our servers are hosted in San Fran. California where Sega of America is, or Sega of Japan? I would assume the first.
