Wi-Fi Fluctuates Wildly, Disconnects - Tops Out 5 Mbps - Dell Inspiron 5559 [UPDATED]

I’ve been using Manjaro on my Dell Inspiron 15 5559 laptop for about 9 months now. This is my second Linux distro and my first on a laptop. I’m still pretty much a newbie.

Every wifi connection I’ve made fluctuates from 0 to around 5 Mbps. I was testing online speed today and my test came back 6.75 Mbps download speed and 7.90 upload speed. I’m on a Frontier FiOS service and router and on my desktop and, using the same test, I get 60 Mbps both directions. Before this installation, the laptop also got 60 Mbps in both directions in Windows 10.

This is very frustrating, considering that I used the open source drivers. The onboard wifi is an Intel dual band Wireless AC 3160 adapter.

Is there some setting I’m missing? Should I switch back to the proprietary driver, and if so, how?

I keep seeing other subjects that are for other PCs, but not mine, specifically, so I worry that the solutions won’t work for my setup.

Any assistance or information anyone can provide would be greatly appreciated.

My thanks, in advance!

Pax, harmonia,


Also, here’s my speed test, as well as my wifi connection, that shows it at 0 B/s:
