re-bob: Reported Version is OpenWrt 19.07.4 r11208-ce6496d796 with other device no disconnection occurred |
re-bob: I have found other similar problems and is a kernel/driver problem, see [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/548992|https://bugs.launchpad.net/ubuntu/+source/linux/+bug/548992]] [[https://ubuntuforums.org/showthread.php?t=881354&s=a943200d2c6e31236f47bfebb4148917|https://ubuntuforums.org/showthread.php?t=881354&s=a943200d2c6e31236f47bfebb4148917]] |
