I need to correct myself: the card stopped working out of the blue and started to print Tx status -71 to dmesg. So the statement "network works perfectly while the computer is turned on" is not true.
Excerpt from the dmesg: [11284.014421] audit: type=1400 audit(1617704946.490:148): apparmor="DENIED" operation="capable" profile="/snap/snapd/11588/usr/lib/snapd/snap-confine" pid=24752 comm="snap-confine" capability=4 capname="fsetid" [11292.590915] audit: type=1400 audit(1617704955.062:149): apparmor="DENIED" operation="open" profile="snap.chromium.chromium" name="/run/udev/data/c510:0" pid=24752 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 [11292.590920] audit: type=1400 audit(1617704955.062:150): apparmor="DENIED" operation="open" profile="snap.chromium.chromium" name="/run/udev/data/c510:1" pid=24752 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 [11328.103406] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.111513] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.119627] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.127759] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.135889] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.144009] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.152141] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.160250] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.168395] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11328.176506] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11333.085154] retire_capture_urb: 2492 callbacks suppressed [11333.110654] net_ratelimit: 596 callbacks suppressed [11333.110660] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11333.118785] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [11333.126913] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922651 Title: r8152 tx status -71 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1922651/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
