Since a couple of days, my QNAP NAS TS-219 is dropping its WiFi connection,
after which I can only reboot the system to get it back (as far as I know).
Although I am not sure at all, this seems to coincide with my update of the
linux-image* package, and hence the report here. Please reassign if you know
where this belongs or feel free to close it if it really doesn't make sense.
I updated the image on 2016-06-05 around 10:27:07 and am running that now
(although I don't really remember if I rebooted immediately):
paul@fuji ~ $ uname -a
Linux fuji 3.16.0-4-kirkwood #1 Debian 3.16.7-ckt25-2 (2016-04-08) armv5tel GNU/Linux
My WiFi dongle is connected via USB (the first device):
paul@fuji ~ $ lsusb
Bus 001 Device 004: ID 1737:0079 Linksys WUSB600N v2 Dual-Band Wireless-N Network Adapter [Ralink RT3572]
Bus 001 Device 003: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
In the syslog I see the following error messages about every 50 seconds, which
doesn't seem to appear when I still have a connection:
Jun 14 21:15:04 fuji kernel: [177628.821851] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x101c with error -110
Which for the very first time after reboot that this appears may be right after
the following items:
Jun 13 00:36:05 fuji kernel: [16895.965179] ieee80211 phy0: rt2800usb_tx_sta_fifo_read_completed: Warning - TX status read failed -75
The first time I can now spot this in my syslog is on 2016-06-08 00:04:35,
unfortunately, my syslog before 2016-06-06 06:25:11 is lost.
Until last week I never had any issues with the WiFi since I installed Debian
on this NAS, which was somewhere in May 2014.
At first, I thought the issue was cause by OOM of my device (no idea yet where
that is caused by) but since my last reboot, there were no OOM issues and still
the WiFi was dropped after it worked correctly initially after the reboot.
Please let me know if I can help with more information.
Paul
