[Bug 1451233] Re: Realtek RTL8723BE drops connection until reboot
I made a ppa with new Realtek wireless drivers. They fix most of issues. Theu can be installed by sudo add-apt-repository ppa:hanipouspilot/rtlwifi sudo apt-get update sudo apt-get install rtlwifi-new-dkms linux-firmware Note: For some usb dongles this combined driver does not work well. There is a standalone driver, that can be installed from same ppa sudo apt-get installed by sudo apt-get install rtl8192cu-dkms There is also a bluetooth driver for rtl8723be/rtl8723au combo chip. sudo apt-get install rtl8723au-bt-dkms -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1451233 Title: Realtek RTL8723BE drops connection until reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1451233] Re: Realtek RTL8723BE drops connection until reboot
Paweł Kowalik, just to clarify, if you have to use WORKAROUNDs like fwlps/ips=0, then the root problem of having to adjust those parameters wouldn't be considered solved. Also, regarding filing reports upstream, it's not considered an upstream issue unless you have tested the latest mainline kernel (not default Ubuntu kernel). Hence, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
