NetworkManager does not show available Wi-Fi networks; iwconfig+dhclient work -- Intersil Prism 2.5 Wavelan orinoco_pci, hostap_pci

Binary package hint: network-manager

After upgrade to Lucid-RC, the Network Manager applet no longer shows available networks.

However, if I disable management of wireless networks in NM, it is possible to connect with

sudo iwconfig eth1 essid mynetwork key s:asciikey
sudo dhclient eth1

The SSID for the interface shows

eth1 IEEE 802.11b ESSID:"linford"

with Network Manager, but

Network card is Prism 2.5 using orinoco_pci

lsmod|grep orin
orinoco_pci 2655 0
orinoco 62841 1 orinoco_pci

Unfortunately, hostap has been broken since Karmic 2.6.31.10

I had the same issue with a live CD boot of Lucid-RC (kubuntu/x86) on a ThinkPad T30 (type 2366-JBU). With network-manager running, the ESSID is garbled. When I use "service stop network-manager" and then manually configure the ESSID, it shows up properly.

The card is an IBM branded Prism 2.5 MiniPCI (OE with this model) and the firmware revs are 1.1.0 for the primary and 1.8.2 for the secondary.

I'm going to download the released version and retry.

@Chris, John: Has this been fixed in Ubuntu 12.04?
