Wifi problems, D-Link DWA-140 Rev. B2, rt2870

Hi!

I've tried to get my D-Link DWA-140 Rev. B2 USB adapter to work for a few days now. From my research I've found out that should™ work out of the box but it doesn't. The USB adapter fails to load entirely.
uname -r

2.6.31-ARCH

lsusb:

Bus 003 Device 009: ID 07d1:3c0a D-Link System

I Google'd 07d1:3c0a and found out from the LKDDb I've found that the rt2800usb driver should do the trick, the device ID is found in the list of recognized hardware. (http://cateee.net/lkddb/web-lkddb/RT2800USB.html),
lsmod | grep rt2800usb:

rt2800usb              41280  0 
rt2x00usb              12512  1 rt2800usb
rt2x00lib              35936  2 rt2800usb,rt2x00usb
crc_ccitt               2208  1 rt2800usb
usbcore               183764  7 rt2800usb,rt2x00usb,usb_storage,usbhid,uhci_hcd,ehci_hcd

Great, the driver is loaded but is not used, and (obviously) the device does not work...
dmesg:

usb 3-1.2: new high speed USB device using ehci_hcd and address 12
usb 3-1.2: configuration #1 chosen from 1 choice
phy2 -> rt2800usb_init_eeprom: Error - Invalid RT chipset detected.
phy2 -> rt2x00lib_probe_dev: Error - Failed to allocate device.

So, the chipset is invalid? What, the ...?
Check my /usr/share/hwdata/usb.ids
excerpt from usb.ids:

    5100  Remote NDIS Device
    f101  DBT-122 Bluetooth

So, my usb.ids is not the same as the kernel 2.6.31 usb.ids at the LKDDb website. My device is not in it. Oh, the USB adapter does not work in Ubuntu either, even though it should work OotB according to Ubuntu website.

Any ideas?

PS. If you wonder why I havn't installed any ralink drivers yet, it's because it SHOULD work without them ...

Re: Wifi problems, D-Link DWA-140 Rev. B2, rt2870

According to the commits in the kernel git repository (see link below) the rt2800usb driver in kernel 2.6.31 should recognize the ID of my device. This is really getting me out of my comfort zone and competence. According to all information I've gathered my device should be recognized and work without any tweeking. Am I missing something?

PS. I missed to inform you in the first post that I run the x86_64 version of Arch, if it have any relevance.

Hi!

Just having bought the same adapter, I am having exactly the same problems. Did you solve it or has anyone else got a solution? Running x86 by the way, so the problem isn't with x86_64.

The best solution I found to make DWA140 B2 work is to use ndiswrapper and wpa_supplicant. For more explanations, see my article here : http://blog.grenlibre.fr/2011/01/how-to … k-on-linux

EDIT: sorry, I should have noticed that the original posts are quite old... I apologize.

Is it an option to update your kernel to the current 2.6.36? Also, what is your version of usbutils (the package owning usb.ids)?

With current packages from the repos, I do find your card:

        3c16  DWA-125 Wireless N 150 Adapter(rev.A2) [Ralink RT2870]
        3301  DWA-130 802.11n Wireless N Adapter(rev.C1) [Realtek RTL8192U]

As you can see, 3c0a is there.

So I suggest you update your system and try again

Re: Wifi problems, D-Link DWA-140 Rev. B2, rt2870

I'm in the mean time running on kernel 3.0.1.
With the kernels before that (2.6.38 and 2.6.39) I used the driver from ralink which was in staging (rt2870sta). This driver was very solid (even though in staging). Download speed was also very constant.

In 3.0.1 they decided to kick out the staging driver so you're only left with the serialmonkey driver (rt2800usb). Reason : the rt2800usb did not get debugged enough (probably because people were using the ralink driver instead).

On my first reboot in 3.0.1 my wireless connection was gone .
I did have a problem with dhcp : it timed out. I increased the time out interval and now it works again. Although download speed is not always constant ...

So I suggest you upgrade you kernel

Re: Wifi problems, D-Link DWA-140 Rev. B2, rt2870

I can confirm the issue. Just after the kernel 3.0.1 update, my DWA-140 usb wifi couldn't perform dhcp connections (time out).
So I added

TIMEOUT=60

to my netcfg profile and now it works perfectly again.

I can't report any speed issue since I have a very bad connection down there, but it seems to work as good as before.
