I'm not sure which sub-category is best for this query, but I thought this might be a good place to start.
I have a PS3 which I use as a media centre, wirelessly connected to my D-link wireless ADSL router (the one Telecom provide), and have problems where the PS3 drops the media server connection randomly but quite frequently. The connection to the router itself stays intact but I will be watching a video file and all of a sudden it will stop playing, the PS3 will tell me that the connection to the media server has been lost, then about 2 seconds later the media server icon re-appears and I'm good to go again.
I have experimented with changing the wifi channel - the signal strength is at about 60% and videos start to play after about 2 seconds so I figure that signal reception is not the problem. I have also tried running a LAN cable across the house for a wired connection and with this I experience no drop-outs at all so I am fairly certain that the configuration of my LAN is not the problem either.
Has anybody else experienced this issue? Does anybody have any ideas as to what might be causing this?
