[lubuntu] Wifi Coection discoects and recoects + Wifi is slow

First up sorry for the length of this post, and my newbieness, although I've been a user of lubuntu for a while, I'm still pretty new to a lot of it's ier workings. I currently have lubuntu 16.04.1 installed on a HP Compaq nc6220 laptop.

Anyway, I noticed a few months ago (quite possibly when I upgraded to 16.04, but I can't be sure to be honest) that my wifi coection has a habit of discoecting itself then recoecting. I also noticed that my coection is quite slow - based on speedtest.net my girlfriends laptop next to me always gets at least 10mbps download speeds, whilst I vary between 4mbps al the way through to 10mbps.

After looking at other threads here I tried to install wicd and remove network manager as I heard that can help, but made some mistakes along the way and somehow removed the ability to coect to the inteet (or I just didn't know enough to fix it myself!). So I though I'd do a clean install of 16.04.1 (erased everything on the drive after backing up), but alas the same problems persist.

I went through this article here about speeding up inteet on ubuntu, but none of it works for me; https://itsfoss.com/speed-up-slow-wi...ection-ubuntu/

Solution 1: For Slow WiFi in Atheros Wireless Network Adaptors - I don't think I have atheros based on the output from lshw -C network below so doesn't apply;

Solution 2: Disable 802.11n - Ruing sudo rmmod iwlwif results in:

Code:

rmmod: ERROR: Module iwlwif is not currently loaded

Solution 3: Fix the bug in Debian Avahi-daemon - /etc/nsswitch.conf doesn't have the problems listed (it says hosts: files dns as it should do)

Solution 4: Disable IPv6 support - I went through the instructions and disabled IPV6 support but it didn't change the speed (is it problematic that IPv6 is now disabled?

Solution 5: Ditch default network manager and embrace Wicd - this could work but I don't know how to do it successfully without stopping my wifi from working completely!

Solution 6: More power to wireless adaptor - Ruing sudo iwconfig results in;

Code:

enp16s0   no wireless extensions.

I can tu the power managment off using sudo iwconfig wlp2s4 power off, but it doesn't speed up the inteet, and upon reboot power management is back on (as you can see above!).

Finally, in case this helps, here is the output from ruing the wireless info script:
