    No Network Access on 10.04

    Hey guys,

    I purchased an Acer Aspire 7745G yesterday and installed Ubuntu as soon as I opened up the computer.

    There appears to be a big problem however. Neither the wireless nor the LAN / ethernet are working.

    'ifconfig -a' gives two items: lo and pan0. I believe pan0 is the bluetooth.

    The wireless icon at the top right says "No network devices available". Network Tools shows the same results.

    If I plug in an ethernet cord, nothing happens.

    This is a fresh Ubuntu 10.04.1 downloaded this morning from ubuntu.com. I tried installing three times (USB, CD, DVD) including data checks on the disks. Same problem all three times.

    I am guessing this is some kind of driver issue, but since I have no Internet access, I cannot do a Ubuntu Update and have Ubuntu find the drivers for me.

    Any ideas?

    EDIT: The wireless and ethernet are working in Windows 7.

    Perhaps I'm just mis-interpreting things this afternoon (long day...), but I don't notice a driver associated with either interface.

    Thanks Iowan. Yep, I think you are right. That seems to be the problem: For some reason Ubuntu did not install either the wireless or the ethernet drivers during the install. I am not sure how to get them and install them now. I have no Internet access on the computer.

    Since you dont have internet it will be difficult to install build-essential
    Can you check whether build-essential is listed in synaptic package manager?
    If yes try this(see post #5)
