Hi.
I had D-Link DWA-160 (HW B1, FW 2.00) for a while and it worked on my Debian Linux (I had to install firmware-ralink package for that. It's Debian testing x86_64, kernel 3.11-2, KDE / NetworkManager), but I never managed to connect using n band, (it was always b/g). My router is D-Link DIR-825.
I thought may be there are some issues with older revision, so I just got DWA-160 revision B2 (FW 2.40). But I get exactly the same problem - it connects only on b/g band (which prevents using it with higher bandwidth). Is it a known problem on Linux, or I'm missing something here?
-
Possible problem with drivers for Linux. If you open the security on the main host router and set it to single mode N, WPA2/AES only, does the DWA connect?
-
Some mixed results.
I enabled both channels on my router (2.4 GHz and 5 GHz) and set both to 802.11n only (WPA2 only/AES).
With DWA-160 B1 I can connect to 2.4 GHz as b/g and to 5 GHz as a. With DWA-160 B2 I can connect to 2.4 GHz as b/g and can't connect to 5 GHz at all.
May be there is an updated driver from D-Link which I can compile from source? This obviously seems to be some driver issue, and B1 is even working better than B2.
-
Can you try the adapter on a Windows PC?
-
I don't have one here, but I doubt that would help diagnose the issue, since Linux driver is a separate thing from the Windows one. In my case I'm using the rt2800usb one: http://wikidevi.com/wiki/Ralink_RT5572 (http://wikidevi.com/wiki/Ralink_RT5572)
For B2 it's reported by lsusb as:
D-Link Corp. DWA-160 802.11abgn Xtreme N Dual Band Adapter(rev.B2) [Ralink RT5572]
-
It would check to see if the DWA is working or not. Also you could try RAlink drivers from RALink if they have any Linux drivers.
-
rt2800usb is a mainline kernel driver, but there is a 3rd party one (from the Mediatek, former Ralink, their chipset is used in the DWA-160): http://www.mediatek.com/_en/07_downloads/01_windows.php?sn=501 (http://www.mediatek.com/_en/07_downloads/01_windows.php?sn=501)
I didn't try it yet, since it's reported to work not so well with the new kernels and they didn't update it since 10/22/2012.
My question basically is (if anyone knows), whether not using n band is the limitation of the rt2800usb, or I'm just missing some configuration on my side.
-
If this is useful to anyone, I found support mailing list for the rt2800usb:

N mode is the max supported on the DWA-160 so thats it's only limitation. Configuration of the main host router and drivers should be reviewed to ensure that the signal is N mode.
