Here's what I'm talking about: https://gfycat.com/UnselfishCloudyChimpanzee
In the clip, I visit two websites (youtube.com and miway.ca) while wavemon runs in the background.

Why might signal levels to fluctuate so wildly if just visiting 1-2 websites? Is it Ubuntu, or my router?
This never happened with the other router I used to use. I stopped using it just a few days ago. It's an ASUS 2.4GHz-only router. Speeds were stable, if slow, but I was capped at only 11Mbps with it. Wavemon also didn't go crazy with it like it does with my other router (below).
My WiFi itself is fine... for the most part. Sometimes pages can take a while (30 seconds to 1 minute) to load. Videos generally run with no issues, no matter the website. Downloads speeds are okay--usually averaging 1-2Mbps. I live in Canada and have Rogers Cable. According to speedtest.net, my download speeds on this laptop with my current Ubuntu setup average 21MBps down and 9Mbps up. On really, really good days I get 35Mbps down. Ping is 11ms.
The router this computer is connected to is the ASUS RT-AC56U on its default firmware with the latest firmware upgrades, running both 5Ghz and 2.4GHz networks. No other routers are running in my household except for this one. My laptop can only connect to the 2.4GHz network since it's got b/g/n only WiFi (the RTL8188CE, according to Ubuntu, and Thinkpad 11bgn according to Windows).
There are five other 2.4GHz SSIDs in my neighbourhood. Maybe they're causing signal interference? Any thoughts?
