I installed the linked kernel and the wifi still wasn't working (though
with antenna 1 it didn't even find the wifi in the first place and with
antenna 0 it wouldn't connect (the signal was really really bad though)
so it almost seems as if the problem is even worse than with the 4.13.
Though that could just be coincidence).

Title:
Poor wifi signal with RTL8723BE and 4.13.0-32 kernel
Status in linux package in Ubuntu:
Confirmed
Bug description:
When using Linux Mint 18.3 alongside with the 4.13.0-32 kernel the
wifi signal is really really poor (while almost sitting on the
respective router) whereas with the 4.10.0-38 it works like charm.
I had to use a configuration file for getting the wifi to work
properly (/etc/modprobe.d/rtl8723be.conf: options rtl8723be fwlps=0
ips=0 ant_sel=1) but chaning the antenna from 1 to 0 did not change
anything with the 4.13 kernel.
I am also running Manjaro Linux with the 4.14 kernel on my machine
where the wifi is also working just fine (with antenna 0 though).
cat /proc/version_signature:
Ubuntu 4.10.0-38.42~16.04.1-generic 4.10.17
(I tried using ubuntu-bug linux but it didn't work [The report belongs
to a package that is not installed.])
