Hi,
I just purchased AC5400X and I am using 800Mbps from my ISP. I tested the speed through Ookla Speedtest and consistently getting 800Mbps for 1st time. However after few hours, the Speedtest dropped by 50% to 400 Mbps and I have to restart the C5400X router in order to get back 800Mbps from Speedtest.
May I know why is this happening and any solution to maintain the internet speed in long term?
Thanks

Thanks for the tip. I was about to pull the trigger to jump to Asus but now I guess I will sit with this problem for a little longer. Seem no solution other than keep rebooting the router. It is really sad that no one from the companies care anymore.

The problem I have was never on the Wired devices. Seem LAN ports does get the full bandwidth when you disable the QoS. However, the same cannot be say abut the WIFI side where it keeps dropping after a few hours. In my case, no matter what setting I try to use on the QoS, nothing works on WIFI. Only reboot.

Hello all, apologies for the super late reply.
It is suggested to update the Archer C5400X to the latest firmware released on the local website, which should fix this speed issue you reported.
While if it still persists and we want to try the beta first, here it is:
Note: There is guidance in the download folder and you may refer to it to update the firmware.
Do let the community know if the issue is fixed or not, thanks a lot~

Contacted local tplink support and my issue is fix now. Need to do hard reset and flash with firmware as mention in website for the latest.
Note to taken where u run speed test from router it alway ovsrite the speed in homecare. If your speed getting slow from ur device that because the qos speed had been reduce time to time when ubdoing speed test.

The slow speed is from LAN or Wifi? Or thr speedtest done in router apss?
Is thisnhappen in ur previous ? After reboot u get the same issue?
If after reboot ur speed remain half then i beliefe something sifferent issue from us. We get speed slow down after few hours and the speed restore every reboot.
Which package you using?

@Leonlay my speeds going into router are what im supposed to get 600mbs but if I connect thru ethernet or wifi from the router it cuts it down to 200mbs or lower. I tried the beta firmware update and the newest update, still having the lower speeds.

Hey @Kevin_Z,
I was already running the latest version from the website:1.1.2 Build 20191223 rel.73956(4555)
The beta you linked, is it EU or US? or it doesn't make a difference? The download website says it does, but I'll install the beta if you say it's ok.
Also, isn't this beta older than the 1.1.2 release? at least in date they are, although I see the version is 1.1.4
Thanks

Hi, thanks for asking.
The beta we provided in my previous reply is older than the latest version published on the website, do you mean you still have the half speed issue with your C5400X? If you would like to give it a go, this beta can work for both EU and US versions.
Good day.
