We've made progress. I've tested the rt2870.bin file from linux-firmware 1.53 which works :-). You still have to blacklist rt2870sta because otherwise nothing ralink-related is loaded. Syslog:

This also works, but not as good as the one from linux-firmware. NetworkManager is reacting slow on connecting/disconnecting and the syslog shows the following: Jun 2 09:33:13 sixpack kernel: [ 288.072780] phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x1328 with error -71. But the one from linux-firmware is working great, I will test it for some days to check its stability, speed etc. Thank you for your help + your explanations, I learned a bit more about linux' wifi architecture. :thumdsup ** Attachment added: "MD5 checksums of different rt2870.bin versions" https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/762987/+attachment/2151762/+files/md5sums -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762987 Title: RT2870 WLAN Stick (D-Link DWA 140) not working. firmware does not support detected chipset -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
