network manage doesn't offer wireless

[Ralf Hildebrandt]

$ lsb_release -rd
Description: Ubuntu jaunty (development branch)
Release: 9.04

Wireless is not being recognized by network-manager.
wlan0 is up, though:

$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:22:69:09:2f:1e
          UP BROADCAST MULTICAST MTU:1500 Metric:1

          RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

$ iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:""

unloading and loading the ath5k driver doesn't work either:

The network-manager-applet still has wireless disabled.

The Acer Aspire One netbook is affected.

Workaround is to use wicd instead of NM for the present.

setting to confirmed; see UF thread.

[Ralf Hildebrandt (ralf-hildebrandt)]

I can also confirm that it must be due to NM, since I was successfully using ubuntu jaunty's 2.6.28 kernel in intrepid, and awireless ceased to work after switching to jaunty altogether. So it cannot be the kernel.
