The above sequence without the second "iwconfig" works fine with a RTL8187 device. I'm running compat-wireless-2.6: master-2009-07-26-11-g83c091c wireless-testing: v2.6.31-rc4-29204-g6b3a8c9 on top of a 2.6.30 kernel. The WLAN NIC is a: 02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01), PCI id: 168c:001c (rev 01) ath5k identifies it as: ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70) It's not a big issue, but a bit annoying sometimes.
