[maemo-users] N800 wifi power usage

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 

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.
