With Ad-Hoc mode: No.

If the PC could make itself appear as a basestation then in such case power-management (and WPA) would be available.

Unfortunately there is no sane way for the PC to "host" the connection even if in theory DHCP (and via that routing information) could still be served from the N900.

("why not sane": it would require separate hosting programs for each OS, and depending on the wifi drivers etc it might or might not work. While Linux makes stuff like this easy [supposing proper drivers are available] you can count me out of trying to develop something for windows).

As for windows, at least Realtek wifi utility has a "Software AP" feature. Haven't test it though. In this case you just specify gateway adress on the PC = N900 adress and you should be done.

I think ASUS has the same option.
In my case it's Atheros under Win7, I use windows to maange wifi.

Besides, there have been rumors about finally implementing p2p mode to wireless adapters as standart.

As long as your operating system is Windows 7 and the drivers support Virtual WiFi, your PC can act as an AP:

If you haven't tried it yet - I just discovered this today - even if you are prompted with the error message "Mobile Hotspot failed to start", if you see a data connection established, your MH might still have connected.

I kept receiving the error after the tether was broken due to an incoming call. I reinstalled the app several times, rebooted, physically deleted /opt/mobilehotspot/libs etc. to no avail. Finally decided to try it despite the error, and here we are, using it as we speak. [Using Titan's latest kernel]

Hi,
recently mobilehotspot doesn't work any more on my N900; in particular, I can't find its essid network name with my other devices. The log seems normal:

you're using stock kernel, (re)install titans kernel for power users, reboot and try again.

the log indeed looks normal, I have no idea why the ssid would not be visible to other devices sice iwconfig does not return failure either.

I have been unable to get this to work. I do not have FMMS installed. Pretty sure I have titan's kernel installed. My other devices see the N900 and connect to it but internet does not work on them (although I seemed to have been able to get my Galaxy Tab to work- but peharps it was only going to pages stored in the cache memory).

When I run /usr/bin/mobilehotspot in xterminal I get the following:

ERROR:dbus.proxies:Introspect error on :1.88:/com/nokia/icd2: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NotSupported: Unsupported interface or method
