Hi Everybody!

Do you know that this is an Arch problem?  I suspect it is an Android problem, in all likeliness, a problem deliberately created by your phone carrier.

Be that as it may, does tether work on other OSes?  Also, to get my Android to tether (both USB and wireless), I had to change the iptables on the phone to allow it to route correctly from the wlan to the 3g network:

# uname -a
Linux localhost 2.6.37.6-cyanogenmod+ #6 PREEMPT Mon Jan 23 23:31:52 PST 2012 armv7l GNU/Linux
# cat /data/local/userinit.sh
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -P FORWARD ACCEPT
iptables -t nat -A POSTROUTING -o rmnet0 -j MASQUERADE


# 

Make a file like that, reboot, and check your iptables config.  [In case it is not obvious, I am talking of the phone itself]

Re: tethering internet from my Android device doesn't work

a couple of month I was able to tether without a problem, I think the only difference is that I'm using cyanogenmod 10-1 and before was cyanogenmod 10-0, because of this I was thinking it was a arch/linux problem. I even called my phone service provider and it was alright.

I created userinit.sh with the information that you gave me, but I don't know how to write on /data/local/, could you tell me how? please

Re: tethering internet from my Android device doesn't work

Yeah, this is turning to an Android tread, so we will keep it quick.

ewaller$@$odin ~ 1004 %pacman -Qo $(which adb)
/opt/android-sdk/platform-tools/adb is owned by android-sdk-platform-tools r16.0.2-1
ewaller$@$odin ~ 1005 %adb shell
# 
# bash
localhost / # uname -a
Linux localhost 2.6.37.6-cyanogenmod+ #6 PREEMPT Mon Jan 23 23:31:52 PST 2012 armv7l GNU/Linux
localhost / # which vi
/system/xbin/vi
localhost / # 

Install the android package, tell the phone to allow ADB debugging, and use a shell
