That configuration is likely to not work with any normal AP. IEEE 802.11
requires that the station supports all basic rates of the AP. In most
IEEE 802.11b APs the basic rate set is {1}, {1, 2}, or {1, 2, 5.5, 11}.
In other words, if you remove 1 Mbps from the support rate set of the
station, it will not associate with any of the APs with the basic rate
sets listed above.
