You have a working driver for your device. However, as your paste result shows, the signals to all available networks is quite weak. This makes it difficult to connect and, once connected, it makes it difficult to stay connected reliably.
Quite often, the weak signal is a symptom of the antenna wire being connected to connection #1 on the card when the default driver is expecting to see the signal at connection #2. Of course, you could open the laptop and switch the wire or you could implement antenna selection at the driver level.
From the terminal:
sudo -i
echo "options rtl8723be ant_sel=2" > /etc/modprobe.d/rtl8723be.conf
exit
Reboot. Is there any improvement? If not, run the sequence again with ant_sel=1 and reboot again.
We also see some things that you might tweak to make your connection more reliable.
First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.
Next, I recommend that your regulatory domain be set explicitly. Check yours:
sudo iw reg get
If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:
sudo iw reg set IS
Of course, substitute your country code if not Iceland. Set it permanently:
sudo nano /etc/default/crda
Change the last line to read:
REGDOMAIN=IS
Proofread carefully, save and close the text editor.
Is there any improvement?

To replace it with a different driver or to stop using the internal wireless altogether? The approaches are different for each. – chili555 Sep 12 '18 at 13:12

If you want to get rid of it completely, blacklist it. From the terminal:
sudo -ifollowed by:echo "blacklist rtl8723be" >> /etc/modprobe.d/blacklist.conffollowed by:exitReboot. – chili555 Sep 12 '18 at 20:14 -

Screw up your computer?? How? Above, when I asked if you wanted to replace it or remove it entirely, you said remove. Did I misunderstand you? Please start a new question and give us full details. – chili555 Sep 13 '18 at 21:49
