Model: Archer C5400X  
Hardware Version: V2
Firmware Version: 1.1.0 Build 20180904 rel.41828(5553)

Hey Guys!

I own a TP-Link Archer 5400x router which has been working well atleast until I actually looked at my download speeds and did a speed test.... So I have gigabyte internet and realised that I was only downloading at 300 - 400 Mbps and when I did a speed test I got the exact same result. When I reboot my router I instantly get over 1 Gbps download  and test speed but I don't understand why this is happening and how I can fix it so it doesn't happy every day. From what I can tell my speeds reduce again over a few hours until its locked again to around the 300-350 Mbps .

 

I have also tried plugging straight into my modem which fixes the issue so its for sure something to do with the router.... I was thinking maybe a QoS issue but I can't disable it...


Any suggestions?

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:

https://static.tp-link.com/2019/201912/20191206/ArcherC5400x-up-ver1-1-4-P1[20190629-rel24006]_sign_2019-06-29_18.47.02.zip

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~

Okay, that would be great.

 

After you installed the firmware, you can take some time to test its performance. 

 

Any further problem, please let us know. 

 

Best regards.

I actually thought that the issue was resolved with the new firmware but it's still happening.... I was downloading a game on steam at 35Mbps and after a router reboot I am now at 99Mbps which is what it should be. Kinda dissapointed to be honest
