I have a wireless G USB NIC (ZyDAS ZD1211 chipset) which is set up using ndiswrapper. In Windows, the utility that comes with the NIC allows me to set it up as an access point (not ad-hoc).

Is there any way that I could set it up as an access point in Linux?

I'm using Slackware 10.2 and the standard 2.6 wireless modules with ndiswrapper.
