Wire your computer directly to the router and test your pings. 

Test the pings on all other available wireless devices as well, 2.4G and 5G. 

Do you get the same delay?

Ping spikes appear to be present on 2.4G and 5G, but are resolved when on a wired connection. I'd prefer to connect wired, but the layout of my apartment relative to other devices simple doesn't allow it.

I was having the same issue(s) so I changed the DNS settings from automatically receiving from my ISP (Spectrum) to Cloudfare's public DNS server.  

Primary - 1.1.1.1 

Secondary - 1.0.0.1

May not be the true solution but my speeds have gone up, very little latency issues, but then again the AX1500 isn't the most powerful router out there.  If you're needing max speed then you may upgrade to a gaming router that covers like 2,0000 sq ft area.

Thanks,

Is there a specific reason to use Cloudfare, or should I be looking for something specific from my ISP?

@themig35 There are a few different public providers available I believe. You could also try changing to Google's public DNS offering, 8.8.8.8, as well, there's a relevant article here: https://www.allconnect.com/blog/best-free-dns-servers. Cloudflare does claim to be one of the "fastest" though

One other suggestion I would have, did you try turning off smart connect? I had issues prior with the same router wherein if smart connect was enabled, it would cause extremely poor latency on devices connected via wifi anytime a device was connected via ethernet. It would also tend to throw everything on the 2.4ghz band and generally hurt speed (20 versus 200 mbps on the same, ironically wifi 6, device sort of difference, it was wack) in pretty much every instance for me. Given I'm in a small apartment I disabled it entirely and connected everything to only the enabled 5ghz network and got much better performance and the other issue stopped (this was a few versions of firmware back though)
