    WiFi AP for sharing 3G Internet - No AP SSID

    Hi Guys,

    New Ubuntu user here and are liking it a lot.

    I have a problem that I was hoping someone might be able to help me out with.

    Situation

    I have installed 12.04 desktop i388 on my Toshiba laptop and managed to get it working with my 3G internet modem (E1762) all good.

    However, I'm having trouble trying to create a WifI AP with the laptop to 'share' my 3G internet.

    I have created a "New Wireless Network" AP as follows:

    SSID: ubuntu
    Mode: ad-hoc
    band: automatic
    IPv4: Shared to other computers
    Security: 128 bit WEP

    When I enable this WiFi AP, Ubuntu appears to create the network, however I can't find the Wifi Network when I search for it using my other WiFi devices. It is nowhere to be found.

    Am I missing something?

    TIA,

    Mike

    I wonder if your WiFi card doesn't support adhoc mode.

    Do you know which wireless hardware you have installed? If not, please paste us the output of this command:

    Does your other device support adhoc networking? like many phones and tablets have no support of adhoc.

    That might be a good point. I found another forum thread with a similar question, and they solved it by following a tutorial to make their Android phone recognize the network.

    See: http://ubuntuforums.org/showthread.php?t=1977556

    Do you have any other laptops you can test this Ad-Hoc hotspot with in the meantime?

    My phone is an Android Google Nexus S. I'll follow the link and see if it contains anything that might help.

    Mike

    EDIT:Have checked out links and looks like it wants me to root the phone to install software patches... I don't want to do that so I guess my phone just cant connect to ADHOC networks.

    Thanks for the help regardless.

    I mentioned your problem to my coworker who owns an Android phone, and he looked at me like I was insane when I asked if his phone could connect to Ad-Hoc networks. He's done it many times.

    He has an HTC Thunderbolt. What sort of phone do you have? (Then again, I know his is rooted)

    I have the same problem with the same scenario. I manage to get the 3G connection up and running, I create a wireless network with NetworkManager, but it cannot be found by my other computer.

    My wlan card is an Atheros ar9285, does it support adhoc?
