    D-Link DWA-140 / Ralink 2870

    I've inherited an oldish XP PC and am attempting to revitalise it with an Ubuntu installation. I have never really used Linux before now and everything so far has been painless-ish. But configuring the wireless has been a total nightmare!

    The PC originally had a D-Link PCI card which for the life of me I could not get to work, at all. No respoonse, no lights, no recognition by Ubuntu. I tried and failed many times to get ndiswrapper up and running. I gathered that the chipset for this particular card was quite awkward in Linux and considering that it was quite old, I decided I might as well get a new, more convenient USB wireless n adapter. I found a page of wireless cards and adapters which worked out of the box in Ubuntu.

    So now here I am with my D-Link DWA-140 which I was informed would 'just work', running into nothing but dead ends and once again trying and failing to configure ndiswrapper as a last resort. I'm extremely frustrated and frankly can't believe how a fairly popular OS can be so outrageously incompetent when it comes to increasingly ubiquitous technologies like WiFi in the modern world. I want to love Linux, but it's not making it easy for me.

    Any nuggets of advice?

    First, you probably don't need ndiswrapper. Second, the most common issue is two or more conflicting drivers loading, which is fixed fairly easily with blacklisting.

    May we please see:
    Code:
    lsmod | grep -e ndis -e rt2
    ls /etc/modprobe.d | grep -e ndis -e black
    Thanks.

    How about posting the same details?

    Thanks chili555 - I hope it is easy to fix as you say. I've got:

    andrew@ubuntu-desktop:~$ lsmod | grep -e ndis -e rt2
    andrew@ubuntu-desktop:~$ ls /etc/modprobe.d | grep -e ndis -e black
    blacklist
    blacklist-ath_pci.conf
    blacklist.conf
    blacklist.conf~
    blacklist-firewire.conf
    blacklist-framebuffer.conf
    blacklist-modem.conf
    blacklist-oss.conf
    blacklist-watchdog.conf
    ndiswrapper

    Re: D-Link DWA-140 / Ralink 2870

    So, neither the native driver nor ndiswrapper are getting loaded. Let's take the easy way out:
    Code:
    sudo modprobe ndiswrapper
    iwconfig
    Was a wireless interface created? Can you connect?
    blacklist
    blacklist-ath_pci.conf
    blacklist.conf
    blacklist.conf~
    blacklist-firewire.conf
    blacklist-framebuffer.conf
    blacklist-modem.conf
    blacklist-oss.conf
    blacklist-watchdog.conf
    ndiswrapper
    Also, you do not need both a blacklist and blacklist.conf file. Let's consolidate. Open a terminal and do:
    Code:
    cat /etc/modprobe.d/blacklist
    Leave that terminal open and open a new one and do:
    Code:
    sudo gedit /etc/modprobe.d/blacklist.conf
    Transfer all the listings in blacklist to blacklist.conf. Proofread carefully, twice. Save and close gedit. Now do:
    Code:
    sudo rm /etc/modprobe.d/blacklist
    If the procedure above produces any errors or does not start your wireless, please post:
    Code:
    lsusb
    Thanks.

    Thanks - I followed all those instructions. No luck though; I just get 'no wireless extensions for 'lo' and 'eth0'. No wlan entry. The actual USB adapter isn't showing any signs of life either.

    Re: D-Link DWA-140 / Ralink 2870

    I performed the commands as recommended. The first set is with the usb unconnected.

    Code:
    chris@hpdv5k:~$ lsmod | grep -e ndis -e rt2
    chris@hpdv5k:~$ ls /etc/modprobe.d | grep -e ndis -e black
    blacklist-ath_pci.conf
    blacklist.conf
    blacklist-firewire.conf
    blacklist-framebuffer.conf
    blacklist-modem.conf
    blacklist-oss.conf
    blacklist-watchdog.conf
    chris@hpdv5k:~$
    This next set of code is with the usb inserted.
    Code:
    lsmod | grep -e ndis -e rt2
    chris@hpdv5k:~$ lsmod | grep -e ndis -e rt2
    chris@hpdv5k:~$ 
    chris@hpdv5k:~$ ls /etc/modprobe.d | grep -e ndis -e black
    blacklist-ath_pci.conf
    blacklist.conf
    blacklist-firewire.conf
    blacklist-framebuffer.conf
    blacklist-modem.conf
    blacklist-oss.conf
    blacklist-watchdog.conf
    chris@hpdv5k:~$
    I noticed my code was differetnt from Drewkman so I am pausing.

    @alliance1975 -
    May we see:
    Code:
    lsusb
    We need to know if you have the same device. Your modprobe.d files look fine.

    @Drewkman -

    Please do:
    Code:
    sudo modprobe rt2800usb
    iwconfig
    Any signs of life? If not, please post:
    Code:
    dmesg | grep rt2
    cat /etc/modprobe.d/blacklist.conf | grep rt2
    Thanks, guys and gals!
