[SOLVED] Can't connect D-Link DWA-160 to 802.11n router

[timek718]

I have a Linksys 310n (Rev. 1) router and a D-Link DWA-160 usb wireless dongle.

After blacklisting the rt2800usb driver, I was able to connect as a 802.11g client. I have been completely unsuccessful in connecting in Kubuntu Maverick to my router as a 802.11n client.

I fiddled with encryption: setting it to WPA2/AES in the router. I set the router to use only 802.11n. I fiddled & I futzed with KnetworkManager & wicd. I've deleted profiles & created new ones.

Just to make it all more aggravating, I can connect as a 802.11n client when I boot into Windows 7.

Obviously, I'm missing something. Can anyone enlighten me?

I figured it out.

1) Purge NetworkManager, install wicd & dpcpcd. Once wicd is installed, enable dhcpcd on the external programs tab in Preferences.

1) Download and extract. Compiling the RT2870sta driver for Maverick requires changes in the rt_linux.h file and removing the stock rt2870sta module and enabling wpa_supplicant in config.mk in [DRIVER DIRECTORY]/os/linux/config.mk

from: http://en.gentoo-wiki.com/wiki/Ralink_RT2870

Kernel 2.6.35

Ralink hasn't upgraded their RT2870 driver since July 2010. The version provided on the website http://www.ralinktech.com/support.php?s=2 doesn't compile in 2.6.35, due to some errors. The kernel developers renamed some functions.
[edit] How to fix

-Go to: [driver_dir]/include/os/ and open rt_linux.h
-Go to line 1077 and replace it with:

#define RTUSB_URB_ALLOC_BUFFER(pUsb_Dev, BufSize, pDma_addr) usb_alloc_coherent(pUsb_Dev, BufSize, GFP_ATOMIC, pDma_addr)

-Go to line 1078, replace it with:

#define RTUSB_URB_FREE_BUFFER(pUsb_Dev, BufSize, pTransfer

3) Fill in password & SSID info in the file /etc/Wireless/RT2870STA/RT2870STA.DAT. Instructions can also be found at http://en.gentoo-wiki.com/wiki/Ralink_RT2870.

4)In the driver directory at the command line enter:

make && sudo make install

5. Just for good measure reboot. Start wicd. It should now pick up your network. Proceed as normal. You should now be connecting as a 802.11n client to your chosen router.


If you get the "BAD PASSWORD" error, make sure that dhcpcd is installed & selected in wicd's preferences & external programs.

An addendum. I set my router's channel to one that is unused and has a couple of empty channels between it & the nearest used channels. That helped my desktop with the D-Link DWA160. Now, my desktop reports a steady connect speed of 270Mbs.

Anyone know of a guide to troubleshooting wireless network interference?

What is the interference you are seeing?

There are 7 or 8 routers/networks showing. Most of them use channel 6, 2 or 3 use channel 1. And one uses channel 11. I had "Auto" selected for the wireless channel. But it kept using 1 or 6. So I set the channel to 9. And lo & behold, things work much, much better.
