Hi, I've found that applications that make fairly heavy use of the wlan for more than a few minutes make the whole machine unstable. I'm wondering if it is the same for everyone, or is there a fault with this particular machine? E.g. video plays fine if the video is copied onto the flash, but playing it directly from a http server across the wlan causes the machine to reboot after 10 minutes or so (that's with a full battery, sooner otherwise). Similarly downloading, e.g. downloading large files with wget from a local server that runs the wifi flat out, works for 10 mins or so then it reboots or the wlan goes dead. I saw there was a thread about dynamic PSM a few weeks ago, so I've tried setting it to 0, i.e. full PSM. It reduces throughput which I don't mind, but I'm not sure how much it helps with stability, I think maybe a bit. Thanks, Mike
