I got MobileHotspot to work in my N900 with Macbook and iPad today, after numerous frustrating reboots to the phone, reading this message chain and eventually uninstalling also AutoDisconnect from the phone. I don't know whether AutoDisconnect was a culprit of anything, but after uninstalling it and rebooting the phone - Mobile Hotspot started to work ok.

Rambo has done great job helping people here and his messages in terms of debugging helped also me to get through everything. Now I know that if the hotspot does not work, I can try to drop into Xterm and check with sudo what the backend says and whether there is anyone else blocking port 53.

It would be great to have seamless and bulletproof operation straight out of the box, but all and all I am grateful that this piece of software exists at all.

So thank you and keep up the great work!
