Is there anyway to start the wifi hotspot as infrastructure mode instead of AdHoc?

Android devices, without rooting to edit 1 line of config, will not connect to AdHoc wifi. By running hotpsot in infrastructure mode, other Android tablets can easily share the wifi.

And Android devices now have built-in support to run Wifi Spot as infrastructure, why can't we have the same for the N9 (and other Nokia too)?

I've read someone said it's hardware issue, but my SonyEricsson x10a originally had Android 1.6, Wifi Hotspot was added when the firmware was upgraded to 2.3. It seems more like a software fix, unless when making the x10a, they have forseen there would be a wifi hotspot update after 2 years.
