Yes, I installed b43-fwcutter to extract the adapter firmware, as suggested in linux-wireless page. I did other experiments and I have an update: the issue is only with ad-hoc networks. Moreover yesterday I successufully connected to a Windows ad-hoc network using Network Manager (that is able to force BSSID address to grant access to the same cell of the ad-hoc network) following these steps: 1. I created an ad-hoc network (essid "SkyNet") under WinXPPro, to share my Internet connection via wireless. To achieve this result I manually set 192.168.0.1 IP address and 255.255.255.0 netmask. I also selected connection sharing option under the adapter connected to the internet. 2. Connected to the ad-hoc network using my Nokia E52 phone. The phone and WinXPPro successfully created the network and negotiated IP addresses via DHCP (note that after connection the phone can access internet and navigate) 3. At this point, I connected Ubuntu to the ad-hoc network via Network Manager. dhcpclient founds an active network and connection happens :) (Note that I later I discovered that I can achieve the same result skipping step 2 and manually setting a 192.168.0.x address in Ubuntu via Network Manager profile). However I still have a problem: even if the connection is established, I cannot ping the 192.168.0.1 address and the Ubunbtu laptop can't use the shared internet connection. Here is the syslog printed during the connection (with dhcp negotiation): Jan 18 22:30:23 giuseppe-laptop NetworkManager: <info> Activation (wlan0) starting connection 'Auto SkyNet' Jan 18 22:30:23 giuseppe-laptop NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0) Jan 18 22:30:23 giuseppe-laptop NetworkManager: <info> Activation (wlan0) Stage 1 of 5 (Device Prepare) scheduled...
