Speed at router (RT-AX88U Pro) is as expected, speed at all computers and phones is slow

[WeyldFalcon]

1. My router (RT-AX88U Pro) clocks my internet connection speed at around 1.4Gbps
2. My 2 wired desktops and my laptop clock around .45Gbps
3. My cell phone on wifi clocks around .62Gbps (not surprising)
4. I have 1G NICs on all my hardware except my main computer which is a 2.5G
5. I am using Cat6 cable
6. I turned off QoS
7. I am running Firmware version 3.0.0.6.102_33308
8. If I run speed test on 3 systems (2 desktops and phone) I can get the Download Bandwidth monitor to jump up to 1.4Gbps but not on a single machine.
9. What could be causing this throttling?
10. Follow-up question why are my wired machines getting slower downloads than my wireless cellphone?

When you do a hard reset do you save your settings so you can apply them back or can the settings cause the same issue?

Well that was exciting, tried applying 3 different firmware versions and the 3rd one bricked my router. I can't even get it back with reset button.

how does it know where to send the firmware file to? when it is bricked there is no ip address.
