The first thing I would do is use new SSID's (you can use the same password) with no special characters included in either the passwords or the SSID. I am fairly certain that the microcode for the drivers has changed drastically since you had the Nighthawk.
When moving to different hardware it is recommended to 'sanitize' the network for full performance. Just because you were lucky with the GT-AC5300 doesn't mean you should expect this experience with every other router upgrade too.
I tried "sanitize" the network for performance testings, here are what I did with AX11000:
1. Restored AX11000 to factory default and setup network with new SSID "Test1", "Test1-5G-1" and "Test1-5G-2", I never had these SSIDs before so none of my devices will connect unless for my testing device.
2. Disabled HE frame support and did not enable 160 mhz channels since my testing device (iPad pro 11 inch) does not support those.
3. Sat down right next to AX11000, minimize interference.
4. Connected my iPad to 2.4 Ghz band "Test1", ran 6 set of speed tests using the speedtest.net app. Server "Comcast (San Francisco)" (I live in this area) .
5. Connected my iPad to 5 Ghz band "Test1-5G-1", ran 6 set of speed tests using the speedtest.net app. Server "Comcast (San Francisco)" .
6. Connected my iPad to 5 Ghz band "Test1-5G-2", ran 6 set of speed tests using the speedtest.net app. Server "Comcast (San Francisco)" .
reason for running 2 5G bands separately is because they operation on different set of channels.
My results were:
(I have comcast 400 down / 10 up)

Here are what I did with GT-AC5300:

2. Sat down right next to GT-AC5300, minimize interference.

(Interesting to see all 5g tests reached to 476.x mbps towards the end of the speedtest run and got rounded up to 477)
My ethernet speed tests are about ~470 down for both devices, and all my test data are showing that I am getting about ~20% "over provisioning" from comcast like other users mentioned in this forum. But for AX11000, I am not getting that kind of speed over wireless.
I know my tests are not the most scientific kind, but it mimicked the regular usage scenarios for a regular home user of the routers. I believe most of us are having AC devices and some N devices (e.g. smart home devices)
As you can see, for my 802.11 AC devices, the new AX11000 is not doing any better than the GT-AC530. And GT-AC5300 outperformed AX11000 in every test. My results were totally different from online reviews, which claim there are performance gain for 2.4G (N) and 5G(AC).
Any ideas why? I have gone through two identical AX11000s (I originally thought my first one was defective so I ordered replacement), they are all about the same.
