GT-BE19000AI Issue

Don't be surprised, ISP DNS is the fastest. It's one hop away and sends your request to local resources.

I switched back to ISP DNS...will test tonight

I know the router won't be intercepting it

Not sure what do you mean by "intercepting it". ISP DNS is like any other upstream DNS service.

I mean disabling "Advertise router's IP in addition to user-specified DNS"...my understanding is that setting add's the router as a middleman for DNS and disabling allows everything to go directly to the ISP's DNS. I don't fully understand this setting, but disabling it fixed my lag without any adverse effects.

Use Search for the difference between WAN and LAN DNS settings.

There's a customizable DNS comparator on the Dashboard page. You can add your ISP DNSes to the list. It will compare all of them with the fastest at the top. For the longest time Google was quickest for me here in Southern California, but lately the primary AT&T DNS has topped the list as fastest.

For whatever reason setting the primary and secondary WAN DNS tends to make the comparator test them as "artificially" slower, so sometimes I will change both to other DNS servers completely, check the results, then switch back to my preference.

Be very careful if you are enabling IPv6. I haven't touched anything on the LAN DNS settings as it seems very sensitive, even crashing the Ai router...

OK, thanks for that!

Welp, I lied. It's back to lagging again (haven't tried in several days). I give up. I don't really care about this specific website...I am just annoyed that this is happening, and this just happens to be the one place I notice it. It's not difficult to switch to the AT&T router, but it bothers me that this very expensive ASUS is somehow not faster than my cheap butt AT&T modem/router.

Should I enable MLO maybe? I have the GT6 as my main AI Mesh nodes, with an AC5300 in one of the more remote bedrooms.

@AlphaGator1 That's a pretty complex setup. The GT6 is tri-band but dual 5 GHz. As an AiMesh node each one of those lose control/use of 5 GHz-2 (I suspect). Same with the RT-AC5300 as I just checked it's specs. All nodes including the wired one backhaul directly to the BE19000Ai...

Without seeing the layout, I am hoping you can leave the BE19000Ai as a standalone router, (remove all the rest from it's AiMesh). Set up the Basement GT6 as an Access Point with AiMesh, then try to add the remaining routers to the Basement GT6 as nodes....

I'm not confident this will 100% solve the late evening lag you experience, but it should make for a lot more available bandwidth.... That is how most of my network is setup:
