I would like to operate an ad-hoc network in 802.11b mode. Is this possible with rt2x00 drivers? If yes, how can it be done?

Well adhoc doesn't allow 802.11g rates, so it should fall back into 802.11b mode anyway.

Is this because of the rt2x00 driver or because of the 802.11 standard? I thought you could use any PHY regardless of the type of connection.

Even so, I receive no warnings or errors when I set the link speed to 54M in an ad-hoc connection. Is this normal? Does the fallback you mention take place under the hood?

The iee802.11 specifications limit adhoc to B.
I am not sure how it is implemented in mac80211, but it should follow this rule.

However, I could establish a 54Mbps link between my laptop and my rt61 and observed speeds upto 3MB/s.

When I choose 2Mbps as the rate, does it fall back to 802.11b? I believe 2Mbps is a 802.11b only transmission rate.
