Bug Description

Big problem with this chip, WiFi still drops connection, and bluetooth does not work at all.
However, I can fix WiFi with this https://github.com/lwfinger/rtlwifi_new.
But I still have broken BT, and not only me have the same issue.

We need support for rtl8723be.

Ubuntu 14.04, 3.13.0-37-generic.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I'm using Utopics default kernel and I also got wifi working with https://github.com/lwfinger/rtlwifi_new. I even got bluetooth to work with lwfinger's rtl8723au_bt. But when bluetooth is enabled, wifi is not working very well (unless the signals is very good, the connection becomes slow and unresponsive at times). I know that bluetooth and wifi use the same antenna for this chipset, but I'm hoping it's a driver issue and could be fixed on the software level. I would be happy to debug if needed.

Normally my wifi works well but bluetooth is not working at all. As I don't really know what all this is about, but it seems that the bluetooth can be fixed (at least more or less), I hope someone could take the time to explain to me how I install this new drivers https://github.com/lwfinger/rtlwifi_new (if that's what they are).
