Plasma 4 or Plasma 5?
If you are interested in Plasma 5 then you first need to remove kdebase-workspace.

Arch Wiki:
Plasma 5 is not co-installable with KDE 4 Workspace. If you install it you will be prompted to remove kdebase-workspace. It's a good idea to remove it first and then install plasma-meta or plasma.
The Plasma 5 Desktop workspace is available in the official repositories as plasma-meta or plasma group.

rtl8723be disconnects:
https://wiki.archlinux.org/index.php...tion#rtl8723be
The rtl8723be module is included in the mainline Linux kernel since version 3.15.
Some users may encounter errors with powersave on this card. This is shown with
occasional disconnects that are not recognized by high level network managers (netctl, NetworkManager).
This error can be confirmed by running dmesg -w or journalctl -f and looking for output related to powersave and the rtl8723be module.
If you are having this issue, use the fwlps=0 kernel option, which should prevent the WiFi card from automatically sleeping and halting connection.
Code:
/etc/modprobe.d/rtl8723be.conf
options rtl8723be fwlps=0
