Thread: Problem with Broadcom BCM4312 sharing Access Point for Android phone

workstation: ubuntu 12.04 desktop on dell inspiron 1440.

hello all. since couple of days, trying use laptop ap new android phone can connect it. have broadcom bcm4312 router ethernet connection internet access.
used http://linuxwireless.org/en/users/documentation/hostapd , http://linuxwireless.org/en/users/drivers/b43 let router use b43 firmware , use hostapd.
have installed b43 firmware via

code:

sudo apt-get install firmware-b43-lpphy-installer

, have made access point excellently scanned phone using internet if succeed.
followed instructions following link :
http://nims11.wordpress.com/2012/04/...-access-point/ make access point.

however, @ 'final steps' heading of link used make access point, don't think bash script working me. following output if run script:

code:

winuxuser@magicbox:~$ sudo ./initsoftap wlan0 eth0 internet systems consortium dhcp server 4.1-esv-r4 copyright 2004-2011 internet systems consortium. rights reserved. info, please visit https://www.isc.org/software/dhcp/ wrote 0 leases leases file. net.ipv4.ip_forward = 1  no subnet declaration wlan0 (no ipv4 addresses). ** ignoring requests on wlan0.  if not    want, please write subnet declaration    in dhcpd.conf file network segment    interface wlan0 attached. **   not configured listen on interfaces! l2_packet_receive - recvfrom: network down

, cursor keeps blinking , blinking forever.strange thing after execution of script, totally disconnected ethernet connected internet , have make restart again.

question is, missing in steps cannot forward data packets laptop phone?
phone can see network, , keeps on saying 'obtaining ip address' , after time, gets disconnected , process obtain ip remains forever incomplete...

suggestions gurus?

one more thing add... before executing script initsoftap, execution of

code:

sudo hostapd /etc/hostapd/hostapd.conf

result phone trying obtain ip continuously without luck, now, after execution of initsoftap, following:

code:

winuxuser@magicbox:~$ sudo hostapd /etc/hostapd/hostapd.conf configuration file: /etc/hostapd/hostapd.conf using interface wlan0 hwaddr 00:26:5e:54:e8:eb , ssid 'the_g_spot' wlan0: sta 3e:19:be:1f:ab:b8 ieee 802.11: disassociated l2_packet_receive - recvfrom: network down wlan0: ieee 802.11 disassociated winuxuser@magicbox:~$

i have become clueless should ...
