Well - the heat is not the problem in my case.

i did a small test - tried to set the devices to static ip and connect to the hotspot. when i do this - the connection is established very fast but not working - no internet and no access to the n900 itself.

maybe this is dhcp issue? is there a way to set up static ip using one of the hotspots apps (qtmobile/joiku/script) that it'll work?

so far i was not able to create a working connection using the script (which is the best method for me to start/stop the hotspot). the hotspot is visible to other devices, but a connection to it cannot be made
