Hello All,
For what this is worth, I saw a post on an XDA Developers forum that the guys that made android-wifi-tether have a beta version that supports Infrastructure mode. If anyone reading this particular board is trying to tether their tablet to an android phone that they have rooted, I strongly recommend that they consider this as an alternative. I installed it on a rooted Samsung Epic running stock Gingerbread 2.3.4, and my tablet is a Heropad C8 running Evolution 1.3.5 (Gingerbread 2.3.3) and there seem to be no problems.
The versions that support infrastructure mode are the 3.x version, and they are in beta at this time. For this reason they don't appear in the market, so in order to install them you have to allow non-market apps to be installed on your rooted cellular handset and download the APK files directly from the website. The newest version currently available supports WPA-PSK2 security and MAC address based access control. Also, 4G mode is supported, but I don't live in an area that is serviced by Sprint's WIMAX 4G service, so I can't confirm how well that part works. I can attest to the rest of it, though. It works without a hitch, as near as I can tell.
