Network issues on ubuntu 18.04

I am becoming quite frustrated with my internet connection on my Ubuntu 18.04.2 xfce. The connection is quite unstable at times, symptoms are variable speeds and drop outs. when the instability appears I can ping google (for instance) & run speedtest-cli but web pages take ages to load or time out all together. I need to turn network off then on again to regain connection. I have done the network manager & networkd thing. Here is my network card from lspci: Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 09) Subsystem: ASUSTeK Computer Inc. P8 series motherboard Flags: bus master, fast devsel, latency 0, IRQ 43, NUMA node 0 I/O ports at d000 [size=256] Memory at d0004000 (64-bit, prefetchable) [size=4K] Memory at d0000000 (64-bit, prefetchable) [size=16K] Capabilities: Kernel driver in use: r8168 Kernel modules: r8168 I have done study and tried both r8168 & r8169 drivers/ kernel module combinations. Machine basics are AMD FX-6300 6 core processor, with 8G ram. The ethernet controller is on the motherboard. Any assistance would be most welcome as I am tearing my hair out here. Oh, by the way my router is too far away for direct hard wire so i have a wifi to ethernet device (Dlink DAP1360) to derive my connection.
