Thanks for the feedback. The kernel posted in comment #41 was the first of a series needed for the reverse bisect. There will be about 7 in total. I built the next test kernel, up to the following commit: e002434e2d8f8205619b5b8f1d8e373a2724 The test kernel can be downloaded from:

@jsalisbury: ant_sel=1 with 4.15.0-36 kernel gives no improvement, both ant_sel 1 & 2 yield a poor signal. So, I believe http://kernel.ubuntu.com/~jsalisbury/lp1788997 has the problem fixed, but only with ant_sel=1. -- You received this bug notification because you are a member of Kernel

I've tested with the kernel as recommended and suggest in #25. Wifi with rtl8723b3 works again (like a charm). However, ant_sel must be set to 1 (ant_sel=1) as opposed to kernel 4.15.0-32, which required ant_sel to be set to 2 (ant_sel=2). (e.g sudo modprobe rtl8723be ant_sel=1 vs. sudo modprobe

I'll ping upstream and the author of the patch that was reverted. However, before doing so, we should test the latest mainline kernel to see if the bug is already fixed upstream. Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds
