got turbo ed to 800 Mbps

Huawei HG8240w (modem) --> Linksys WRT 1900 ACS (router) -- > Linksys 16 port Gigabit Switch -- > Cisco 2700 with 2.4 and 5 GHZ radio

Max speed i can get via wired = 490 Mbps download / 216 Mbps upload.

Max speed i can get via wifi from iphone x (5 GHZ radio) being 3 feet away from ap = 92.7 Mbps download / 82.3 upload.

I have enabled the Linksys WRT 1900 ACS Wifi 5GHZ as well. Iphone x download results is similar to the Cisco 2700 ap

Question

1) How to I determine its NOT my fault for not being able to get 800 Mbps - cause if TM fellas were to come to my place and is MY fault then it's 53 myr to them.....

2)92.7 Mbps download speed on 5 GHZ is PATHETIC.....what's going on ?

Any assistance is much appreciated.

Thanks

Wired, i can have about 500+ Mbps but no way near 800 Mbps. Reverting back to the TM supplied router, i get around 500 Mbps as well.

I have a Iphone X which I have made sure it's on the 5ghz band for the Linksys wrt 1900 acs and cisco 2700 ap - both yields only 90+ mbps on speedtest ios app

Any ideas ?
