Solved: how to connect a laptop via wifi and share its access to internet
I've tested several build before. eg: donut, eclair, tattoo...
I remember that I've had one build (Android 2.1 probably) by which I could use wifi to connect my laptop and access the internet.
BUT only by that build. And after that I've tried several build(also include 1.6 and 2.1), but none of them can find the wifi network of my laptop.
I've searched about this problem. It seems that it's because ad-hoc tethering is not working stablely. And I found an app named "android-wifi-tether", but it looks just used to let the computer share the mobile's connection, not the opposite direction.

And I still find a complex way. But I think it's not convinient. If you change a computer, u'll have to change the wpa_supplicant.conf file again, bcz the SSID might be different.

Is there any patch for this?
Finally I GOT IT!!!!!!!
Thx to kallt_kaffe's post: http://forum.xda-developers.com/showthread.php?t=700669
With the build RLS6, I can connect my laptop with out modifying the two files.
And I found the tiwlan.ini is almost the same as in the other build, that's odd. BUT it really works!!!!
Thx again kallt_kaffe!!
