i am trying to set up my laptop as an access point for my Android to use WiFi, so i knew that ubuntu sets the network as Ad-Hoc which is not discoverable by android, So i tried the method explained here -which i found on many other websites- but when i run hostapd.conf this error appears : nl80211: Failed to set interface wlan0 into AP mode nl80211 driver initialization failed. ELOOP: remaining socket: sock=4 eloop_data=0x8e488f8 user_data=0x8e48ea0 handler=0x807c5e0 ELOOP: remaining socket: sock=6 eloop_data=0x8e4aca8 user_data=(nil) handler=0x8086770 this is how my hostapd.conf looks like : interface=wlan0 driver=nl80211 ssid=Any_SSID_name hw_mode=g channel=1 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=Any_password wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP and this is my wireless card info : description: Wireless interface product: BCM43225 802.11b/g/n vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:05:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:73:51:f1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=brcmsmac driverversion=3.2.0-31-generic-pae firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:f0300000-f0303fff
