Yay! - scanning produces quite an extensive list of APs, but most of them don't have SSIDs listed. This isn't in itself too strange, since I know that there are 2 networks nearby each with several repeaters that do not broadcast SSID. However, one of them (chmc_guest) is identified in the scanning output when using -Dwext. - All of the networks show a signal strength of 0. -Dwext shows varying signal strengths for each network. Considering that I am unable to associate with any of them, I have to wonder which driver is producing spurious output. I would also like to note that the maximum Tx Power of the card is significantly different between madwifi and ath5k. In madwifi, it maxes at 17dBm; in ath5k, it maxes at 27dBm. I don't know if it actually is using these values, or if one or both drivers are reporting Tx power incorrectly.
