@LewisD2820 are you using a good quality ethernet cable from the hub 3 to the wan port on your router?

@LewisD2820 How are you measuring the download speed?

@Sandyman0_1 my ax 6000 use to do this. Found it was the wifi security. Wpa3 wpa2 mixed caused havoc. Now i have wpa2 only for 2.4 g ( i have some older devices) and wpa3 only for my 5g devices.

@itip Same here AX6000 workaround...select led's to be off but night mode on and put times as off from 2100 to 2100 My tp link extender though has the same issue but only accepts 2100 to 2059. So...

@skogach i've got the ax6000 have you got a page like this?

@Vrix i had to manually do it. Firmware updater wasn't picking it up. I'm in the UK
