I have a couple of folders enabled for share. I can access these from a MAC laptop wifi and desktop machine ethernet works fine. I can also access these folders via a home theatre system using ethernet cable.
I am using windows 7 ultimate x64 and all my configurations, port forwarding is fine. I have even tried reseting the router and enabling and disabling the upnp feature.
I have left the n900 on for a good while when it is searching for network but doesnt find anything and just stays like that for ages.
