Model: Archer C4000  
Hardware Version: V3
Firmware Version: Latest

Hello, 

 

Original internet plan was 200dl.

Switched plan to 800/50, I'd get around 700/50-800/50 upon router reboot. which is OK if it maintained that speed.

Unfortunately no, it'll drop to 350/50 after 3-6 hours ish.

Upload speed stays high - current plan 800/85.

Same thing, goes back to 350/85 after a bit of time.
 

No devices on priority.

No devices drawing bandwidth.

Currently using Archer C4000

 

Speed test done on tether app - router to nbn. 

 

Any help would be appreciated.

Hello @xO-ArChi-Ox ,

Welcome to our community.

 

Have you been able to reset and configure the router again?

The slow speed that you mentioned is the result of a wireless connection or a wired connection?

Please test the link speed when the internet speed drops:

How to check the associated/link speed on a wireless client.

How to check the associated/link speed on a wired client.

Please connect the PC directly to the modem when the speed drops and test the actual speed from the modem. This is for a comparison.

Thank you for reply.

 

I've done a reset/power cycle of both the NBN box and C4000 router over the weekend.

Same thing. 

1st test 8:48pm - 796.1/92.7

2nd test 9:20pm - 753.7/91.2

3rd test 1:02am - 390.6/81.7

 

All test done are from the Tether APP - I have no wired computer connected to router - only 1 Tapo Hub connected by wire to router.

Since the speed test is performed on the Tether APP, it should be consistent and would not matter if I did the speed test on wired or not?

Is the Tether App speed test just a direct speed test from NBN Box to Router? 

 

thank you.

Hello @xO-ArChi-Ox ,

Thanks for getting back to me.

 

It is recommended to use https://www.speedtest.net or the speedtest APP/CLI(https://www.speedtest.net/apps) to test actual speed.

Each time the speed drops, it is best to use a wired PC to test the speed of the modem to rule out the possibility that the speed drop is caused by the modem.

 

Best Regards.

Hello, during this last week I got a BE550PRO (used/tested it for 4 hours then returned it) - wifi strength and stability on it was actually considerably worst then the C4000.

Since the c4000 was unplugged for 4 hours and reconnected, speed is holding up.

No idea what has happened but seems to be working now.

 

note: the BE550PRO would have weak/drop out signal strength with speed 75/10 while the c4000 would be strong with speed 400+/80. Same computer on wifi.  

 

Thank you, for your help.

Hi @xO-ArChi-Ox ,

In other words, the Archer C4000 still isn't reaching full speed, right?
But at this point, we still need to rule out unstable network speeds on the front-end modem.
Also, have you tried resetting the Archer C4000? Of course, if the current speed is sufficient for your needs, you can continue with this setting.
