My wireless internet is very unreliable, so I usually have to connect to the internet using a cable, but this is very inconvenient.

I tried doing the solution for what seems like a similar problem here, but it still does not fix the issue: 16.04 LTS wifi connection issues with Realtek RTL8723BE adapter ... That is, I created /etc/pm/config.d/config and added SUSPEND_MODULES="rtl8821ae"

$ lspci -knn | grep Net -A2
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter [10ec:8821]
    Subsystem: XAVi Technologies Corp. RTL8821AE 802.11ac PCIe Wireless Network Adapter [1b9a:2482]
    Kernel driver in use: rtl8821ae
    Kernel modules: rtl8821ae

I had a similar issue with Ubuntu a few versions back, and it turned out to be the wireless adapter's power management. I am pretty sure this was fixed in 16.04, but you can check this link to see if it fixes your issue with WiFi:

ubuntu 14.04 wireless constantly disconnects

Hope this works for you too! :)
