I cannot get my wireless to work on my Ubuntu 8.04 machine. I have tried restarting my router. I have tried restarting my computer. I went through the troubleshooting guide in the Ubuntu help file.

The problem is, my computer can detect the network (in fact, it says I have a 100% signal), but cannot connect to it. I think it's a problem with my DHCP.

I can ping myself, but not my gateway or any external servers.

I'm using a D-Link AirPlus DWL-520+ adapter and ndisgtk, which SHOULD make the Windows drivers work.

The network works on Windows, which is on the same computer. (I used Wubi- I have a 15GB installation.)

Edit: Someone should probably move this to the Networking and Wireless forum. I didn't notice that the forum was there!

Either forum would work fine.

And the D-Link DWL-810+ wireless adapter is based on a Texas Instruments ACX-100 chipset... TI won't let anyone look at the info on it, so there are reverse-engineered drivers available. They (supposedly) work pretty well.

A quick check of Google shows that a lot of people had trouble with these cards in Ubuntu 6.06 "Dapper Drake", and I have found one report that it still wasn't fixed in "Gutsy Gibbon".

Can you post the output of a sudo lsmod and a sudo dmesg for me?

[herefishyfishy]

I am using Ubuntu 8.04 (Hardy Heron). I'm not using a DWL-810+, but instead a DWL-520+.

I have to attach the command-line outputs in a .rtf because they are too long to post!

Sorry... I bought an 810+ (Ethernet to Wireless bridge) to replace the 520+ PCI card I couldn't get working... This was waaaaaay back in the day, when I had no idea what I was doing with Linux, and could just about use `cd` and `ls`.

The info on the card still stands. The only error was my getting the name wrong.

Well, you can't ping anything because you're A) not associated to an AP, and (which is more an follow on to A) you don't have an IP address.

It looks like NDISwrapper is failing horribly at setting an encryption mode.

Are you using WEP?

Can you post the output of this command: find /lib/modules/ -type f -iname '*acx*'

I'd like to see if you can get online without the use Ndiswrapper. No reason to use a work around when there's a perfectly good native driver... Unlike Broadcom chips.....

[herefishyfishy]

find /lib/modules/ -type f -iname '*acx*' outputs

/lib/modules/2.6.24-16-generic/ubuntu/wireless/acx/acx.ko

I'm using WEP, but I'm SURE I typed in the key correctly.

I don't know how to install a driver in Linux.

[MorphiusFaydal]

Turn off all NDISwrapper stuff, do sudo modprobe avx, and you should be able to use NetworkManager to finish setting up your card.

[herefishyfishy]

OH NO! I followed your instruction, but...

FATAL: Module avx not found.

I'm wondering if this means I need to reinstall Ubuntu.

No, it means I need to drink more caffeine before typing anything in the middle of the night/early in the morning.

sudo modprobe acx is what it should be. Note the "acx" rather than "avx".

I don't understand how you have an ip & can ping yourself, but DHCP hasn't assigned you anything? That's what you are saying, correct?

What's in /etc/resolv.conf?

He doesn't have an IP. He's pinging 'localhost'

[no2pencil]

Ahhh, good 'ol local host.
Yeah, that's completely independent of DHCP.

Does Ubuntu have anything like dhcpclient or dhcpcd? I know you've narrowed down this issue to the WEP Key, but I'm just curious, as a lot of different distrobutions have different options for obtaining an IP.

[MorphiusFaydal]

IIRC, Debian (and its' derivatives) use dhclient.

But NetworkManager should default to trying to grab a DHCP address.

Also, I don't think it's a DHCP issue. Check the file he posted... In his `dmesg` output, NDISwrapper is showing a *ton* of errors. All the same thing, but....

[herefishyfishy]

Thanks MorphiusFaydal! My internet works great now! Thank you.

[herefishyfishy]

Only problem: I have to run sudo modprobe acx every time I restart my computer, right? How can I make this autorun at startup?
