BCM4313 is handled only by staging brcm80211, Windows XP cannot into master mode.
Master mode on netbook (with brcm80211 driver) don't work: hostapd can't start, airbase-ng works only in one direction (can't receive) and easily panics the kernel. And it is said that bcrm80211 works only in managed mode now.
On the other side, Windows XP can only managed and ad-hoc.
Currently using Ralink USB inside virtual machine with debian which sets it to master mode, but this is unstable: without speed limiting it hangs soon, with limit it hangs after several hours of usage.
How to connect them reliably without additional devices?
