This has been a problem for many of us....it has been discussed in a few other threads also. Honeycomb (by default) won't connect to adhoc wifi networks.
I will donate to anyone who can create a hassle-free turnkey solution for this. Many of us have Android phones that are rooted, so a solution would benefit many. And I am using a Tilt 2, whose Android ROMs do not support BT. So this tethering solution needs to support wifi.
