D-Link DWA 140 USB on v9.10

[markfrancis2008]

Hello, I have recently installed 9.10 and have a strange problem with my usb wireless connection. Im using a D-link DWA 140 (http://www.dlink.com/products/?pid=652), it recognises my home network but wont connect to it.

In the wiki (https://help.ubuntu.com/community/Ha...workCardsDlink) its listed as "Works out of the box on Jaunty Jackalope kernel 2.6.28-11. Module from staging at this time, with zero issue found yet." but I can't seem to find the problem.

Because its a usb and not an internal card, I didnt see much when i put in the segested commands in the sticky, but here is some infomation I could get, I dont know how useful it is.

Any help would be great, thanks.

I'm don't have the answer but I have exactly the same problem. I notice that no one has answered your question in 9 hours.

Every installation of Ubuntu that I have done I have had issues with wireless USB. When I installed 8.04 I had a linksys usb dongle and learned about ndiswrapper and finally got it working. Then I upgraded to 9.04 and wifi broke again. ndiswrapper was now dropped from the distribution so upon recommendation, I bought a Dlink DWA-140 usb wifi stick and was able to get it working. Now I upgrade to 9.1 and again problems.

This is ridiculous. If you google "wifi problems ubuntu" you see that the problems have been continual for many years.

We would appreciate a solution to this problem.

Also, why is wifi so difficult a problem for Ubuntu? Microsoft and Mac OS X upgrades have handled this just fine for me.

This is quite easy to fix. Add the following line to /etc/modprobe.d/blacklist.conf file and then reboot:

blacklist rt2800usb

This file is owned by root, but you can usually edit it using sudo program to run an editor as a root user:

sudo nano /etc/modprobe.d/blacklist.conf

I hope this helps.

THANK YOU!

This worked perfectly.

will this work for my wusb54gc?

[ktuomain]

will this work for my wusb54gc?

I think wusb54gc has different chipset. DWA-140 seems to be using RT2870 chipset (at least mine is using RT2870). This is what lsusb command shows on my DWA-140:

Bus 001 Device 002: ID 07d1:3c09 D-Link System DWA-140 802.11n Adapter [ralink rt2870]

If wusb54gc has the same chipset, it is quite likely that the blacklisting above helps. But if it is not same chipset (I think it is not the same chipset as wusb54gc seems to be 802.11g instead of 802.11n), blacklisting might not help. But it still might be worth trying even if it is using different chipset. If it doesn't help, you should remove that line and reboot again. And please let as know if blacklisting helps with wusb54gc.

I think that the problem with RT2870 chipset is that the system loads or at least tries to load the wrong driver (rt2800usb) which messes up the system. And blacklisting prevents loading the wrong driver. The same problem could also be happening with wusb54gc even if it has different chipset, but I cannot be sure about that.

[AFI420]

the windows driver for my adapter is a rt2870.conf file which i used before with ndiswrapper, but still couldnt get a stable connection to my router. but I remember seeing it say that it was using alternate driver for rt2800


maybe if I blacklist 2800 it will use 2870. do I have to load it using ndiswrapper or is it already on the system?

Thanks!
Also worked for me.

Worked great, thank you ^^

Hmm, I'm another frustrated "relatively" long time ubuntu user (2+ years). The irony is that I bought this adapter specifically because it was green lighted. I was compensating for my VT6566 built into my zotac gf3900g-e that never worked well - sheesh.

Anyway, I downloaded the latest 3070 driver (2.3.0.1) from ralink since I have the DLINK DWA-140 B2 version, but when I open the tar.gz it it's still referencing the 2870. The dat files are RT2870* vs. what I would expect: RT3070*. Also the french guide talks about checking the os/linux/usb_main_dev.c for a reference to my device ID: 07d1:3c0a , but that is nowhere to be found.

I think ralink might have just posted an incorrect driver version accidentally, which all leads to my ultimate request:

Does anyone have the tar.gz file for the version referenced in the french guide (2.1.2.0 or any version prior to the 2.3.0.1 for that matter) that they might be able to post here or email to me? I'd love to have this driver hell behind me finally. Seems like if it's not one thing it's another.

My email is my username here @yahoo.com.

Thanks very much in advance.
