I know that normally you cannot control the OFDM data rate while in adhoc mode, since the IEEE adhoc specification defaults to 11Mbps. However, I've read here that certain cards with legacy drivers can allow you to bypass this normal rate restriction. So, I have two questions.

1. Does the rtx00 driver also allow you to bypass this restriction?
2. Does anyone know (could they list) specific cards that I could accomplish the bypass with (either with the legacy or rtx00 drivers)?

With rt2x00, the driver is no longer in control of these restrictions. That is in control by mac80211,
and as far as I know no option is provided to bypass the restriction.

Well it is a restriction enforced by the driver and not hardware. So when using the legacy driver it doesn't matter which device you use.

Just for pure clarification purposes The restriction is chipset dependent and therefore I can use any raillink chipset based WNIC with a legacy driver to bypass the current restriction?

this part is true

New question When the mode is set to Ad-hoc, is the modulation automatically adjusted to ofdm?
