I've got exact the same issue with 4.2.7-300.fc23 (oops when trying to reconnect).

But it is not as easily reproducible by switching off/on as in bug #1173877 . Can you confirm?

Test patch

This bug appears to be triggered when the interface is shutting down while conntrack is active. Note: I have not seen this bug, and I am guessing on how to fix it. The patch disables the lock in rtl_pci_reset_trx_ring() - it should be safe, but testing is needed.

Please test and report back.

The bug is reproducible by switching off/on on me. The bug report tool comes up when I switch off/on.
I also tried running:

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

But nothing changed.
I do not know how to install this patch. I know it is irrelevant but could you show me how to patch it?

The patch is for the kernel source. To use it, you would need to build your own kernel from source.

As an alternative, you could do the following:

git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout test
make
sudo make install
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be


The above sequence assumes that you have previously installed the git and kernel-header packages.

[Larry Finger] I did exactly what you said. The kernel I am using is 4.2.8-300.fc23.x86_64. Things got a lot better but there are issues need to be solved.

First of all "make" command had an error about an unused variable (I think it was about a variable named "flags" or something. When I hit make again it is not reproducible).

An other problem is that abrtd has about 1000 different bugs about something but they are not able to be reported.

That was a warning, not an error. It should not prevent building. In and case, I fixed it and pushed the new version.

I still have a problem. After a while i get disconnected and unable to reconnect.
