Thanx maskrider. Although I wonder what matching failing implies. Could it be that I have a (slightly) different setup than the race host? Or is it a network problem or ....
Edit> From the FAQ pages on the official GT5-p site (japanese) one could conclude that I have an unstable network connection (Babel Fish translation):
' The グランツーリスモ 5 prologue ' Online (the online) matching error occurring in the race/lace event of mode, there are times when it cannot participate in race/lace. Online of this software (the online) with race/lace of mode, it distinguishes automatically the prayer of the circuit environment which is suited for play as a host, focusing on the host it communicates with the prayer. When there was no circuit environment which is suited for play in the prayer which participates in the same race/lace, matching error becomes easy to come out. Because of that, if possible participating as a host, when it receives, also the your other customer who participates in the same race/lace including to your many customers with good quality circuit environment, matching error becomes difficult to come out. Please refer to the page below concerning decision of circuit environment of the customer and improvement method. When your own circuit how you should have judged environment, is? Online race/lace is the host in the event what kind of ones? Online it cannot participate in the event well
When how you should have judged your own circuit environment, is? < GT5 prologue > Presently in Japan there is various types in available Internet circuit environment, but with this site concerning those which are used mainly with general home "due to" the classification the connected method at three level "of wire network equipment of the contract circuit" "/the radio" it classifies, explains. As for details please refer to the page below. Contract are there some ones in classification of the circuit?
Is the host in the online race/lace event what kind of ones? < GT5 prologue > ' The グランツーリスモ 5 prologue ', there are two roles below in the host in the online race/lace event. (1) start and end of race/lace are managed Communication between all the participation prayers is borne (2) at the time of internal data communication which is in the midst of playing, When from the above-mentioned reason, the host passes through from race/lace midway, race/lace itself ends. In addition, when circuit environment of the host deteriorates, being to be also times when the trouble that occurs it becomes the く where the car around does not travel normally in race/lace please note.
Edit 2>>>>>
PROBLEM SOLVED!!! (sorry for the caps, I'm just one happy 40 year old puppy right now) Connecting the PS3 directly (so not through a router) solved the problem. I have been playing on-line now for a few hours and the connection only failed twice out of some dozens of tries. Too bad though that now I either play on the PS3 or I'm online with my PC (so e.g. no more movie downloading while playing....)
Maybe a better router might still allow more than one connection at a time. Someone has experience with this?
