need help to share internet connection to android phone

[Matadewa]

hi all
i'm using ubuntu 10.10 and usb modem as my internet connection
in windows sually i used connectifity, but in linux my friend suggest me to use hostapd

he success used it, but when i try, it's give result

matadewa@matadewa-K42Jc:~$ sudo ap_ctl --start
Starting hostapd
 You can view the log at /var/log/hostapd.log
Starting dnsmasq
SIOCSIFFLAGS: Operation not possible due to RF-kill
ioctl[SIOCSIFFLAGS]: Operation not possible due to RF-kill

dnsmasq: failed to create listening socket: Address already in use

then when i try to check hostapd log, this is the result

Configuration file: /etc/hostapd/hostapd.conf
nl80211 driver initialization failed.
wlan0: Unable to setup interface.

it's seem driver nl80211 not installed yet in my system
i found this link http://linuxwireless.org/en/users/Documentation/hostapd

but i think it's too complex for newbie like me and my english is worst
can anyone describe it with more simple way?
or maybe give another suggestion how to share interent conection to android phone

I am assuming that you have installed the dhcp3-server package as well as hostapd? I believe on 10.10 this was required for DHCP IP address allocation. Could you also post the output of:

sudo rfkill list all

This would show if your WLAN card is locked in any way. The contents of your /etc/hostapd/hostapd.conf and /etc/dhcp3/dhcpd.conf files would also be very very helpful (the last one only if you have the dhcp3-server package installed).
The configuration which I used to successfully link up my Freerunner phone is here:

http://exain.wordpress.com/2011/03/3...rdusb-adapter/

I suggest you read through that document and try if that guide can help you resolve your problems. It certainly worked for me.

yes you're right i'm instaled too dhcp3-server
this is the output

sudo rfkill list all

matadewa@matadewa-K42Jc:~$ sudo rfkill list all

	Hard blocked: no

# This is a very basic subnet declaration.

# Hosts which require special configuration options can be listed in
# host statements.   If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.

#host passacaglia {
#  hardware ethernet 0:0:c0:5d:bd:95;
#  filename "vmunix.passacaglia";
#  server-name "toccata.fugue.com";
#}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host fantasia {
#  hardware ethernet 08:00:07:26:c0:a5;
#  fixed-address fantasia.fugue.com;
#}

# You can declare a class of clients and then do address allocation
# based on that.   The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.

#class "foo" {
#  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";

yesterday after make a few changed like this http://www.saranglebahinformatics.co...tu-ke-android/ *sorry it's indonesian language
it's success to make i internet from my android phone and not show nl80211 driver initialization failed.
but this time i try to connect it again. . .it's failed again like before

The webpage you quote is subscription only, so I can not see what modifications you have made. But wouldn't the message

Soft blocked: yes

indicate the cause of the problem? Therefore the command

rfkill unblock wifi

should unblock the wireless card, which you then could double-check with another

sudo rfkill list all

I would suspect that the network-manager grabs your wireless card on boot (that's why it is "Soft blocked") and that you have to unblock it before you can use it with hostapd. If you only want to use it with hostapd then I suppose you must prevent network-manager from grabbing it first.
