| Message-ID | <wZblT-6Yt-5@gated-at.bofh.it> |
Package: firmware-ralink
Version: 20180825+dfsg-1
Severity: normal
Dear Maintainer,
Under Debian Buster, a usb wi-fi adapter D-link DWA-130, rev. F1 can
display available wifi services but could not connect
to any of them. An "ip link" command shows:
wlx74dada1c2b5d: <NO-CARRIER, BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq
state UP mode DORMANT group default qlen 1000
link/ether 74:da:da:1c:2b:5d brd ff:ff:ff:ff:ff:ff
The same D-link usb wifi adapter installed on a same make and model
computer but running under Debian Jessie works without problem, able to
connect to any chosen wifi service.
On that Debian Jessie system, ip link shows:
wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode
DORMANT group default qlen 1000
link/ether 74:da:da:1c:2b:5d brd ff:ff:ff:ff:ff:ff
=== Workaround: ===
I am able to make the D-link usb wifi adapter work under Debian Buster
by creating the file
/lib/udev/rules.d/70-wifi.rules
which contains this single line (address comes from device name
"wlx74dada1c2b5d"):
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="74:da:da:1c:2b:5d",
NAME="wlan0"
After rebooting the Debian Buster system with that file in place, the
D-link usb wifi adapter works, and "ip link" shows the now shorter
device name:
wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode
DORMANT group default qlen 1000
link/ether 74:da:da:1c:2b:5d brd ff:ff:ff:ff:ff:ff
The workaround solution comes from:
https://askubuntu.com/questions/826325/how-to-revert-usb-wifi-interface-name-from-wlxxxxxxxxxxxxx-to-wlanx
The discussion in that thread mentions a (Ubuntu studio) kernel having a
low latency, wondering whether the long device name is the source of the
problem?
I have not tried forcing names other than "wlan0" to determine whether
it is "wlan0" that is magical or whether other names would work.
I would expect the D-link usb wifi adapter to work under Debian Buster
without this workaround, as the adapter works fine under Jessie.

Concerning bug 914920, sorry, the subject line ought to be something like "firmware rt2870 cannot connect until device name is shortened" Here's more information about the firmware being loaded when the system detects the D-link DWA-130 usb wifi adapter. $ "dmesg | grep rt" excerpts: [ 7.617423] ieee80211 phy0: rt2x00_set_rt: Info - RT chipset 5392, rev 0223 detected [ 7.632788] ieee80211 phy0: rt2x00_set_rf: Info - RF chipset 5372 detected [ 7.683411] usbcore: registered new interface driver rt2800usb [ 241.595520] ieee80211 phy0: rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin' [ 241.602284] rt2800usb 2-2:1.0: firmware: direct-loading firmware rt2870.bin [ 241.602293] ieee80211 phy0: rt2x00lib_request_firmware: Info - Firmware detected - version: 0.36 Thanks.
