C5400 v2 only half speed on gigabit internet
![](/avatar/avatar-11.png)
Hardware Version :
Firmware Version :
ISP :
I have a gigabit internet connection. Speedtest gives mee 900+ Mbps when wired directly to my modem. Tested with laptop and Apple TV 4K.
A brand new Archer C5400 v2 only provides half the speed - with the same devices wired to it. Cat 6 cables in all tests.
Speedtest from the "Thether" app also shows connection speeds around 4-500 Mbps both up and down - I guess this should test the speed between router and modem.
So - is my Archer a defect unit, or are there fixes for this?

Thanks @mikengail for your valued suggestions, we greatly appreciate it.
Hello all, sorry to respond late.
If you have ever encountered any speed issue with the Archer C5400 V2, please ensure first you are already on the latest firmware version which can be found and downloaded from the TP-Link official website:
https://www.tp-link.com/support/download/archer-c5400/#Firmware
If the speed is still not good as compared with that you can get from the ISP modem directly, log into the web interface of the C5400 and go to Advanced->QoS, manually set the speed to that you get from your ISP, and leave QoS on Standard, then reboot the router and confirm the speed again.
Let the community know if you still have inquiries, thanks a lot~

1. ensure that you have the latest firmware available for your region. If not, upgrade.
2. reboot the modem and then the router (keep the modem connected to the WAN port during the reboots).
In my case, after doing the above I managed to get all the speed from the router that my ISP was delivering and everything is still working well. Good luck . . .

No, it's not defect. I have Xfinity Gig internet with my own modem & C5400. Most of the time I get 940/41. You should consider a factory reset of your router or do a restore from backup, I know it's a pain in the butt for a factory reset. For whatever reason, every week or two my download drops to half of what I should be getting. Unplugging everything and restarting does not get me my speed back. What gets me my speed back is a restore from backup or just a plain old factory reset. I'm doing this on a weekly basis, which is pissing me off. Other than that, my c5400 provides excellent connections both wifi and ethernet.
P.S.
I dropped the Gig speed internet for Blast Pro 250/11 ........ Gigabit was overkill for me, didn't really see a big difference. My equipment is pushing out 290 down which suits my household well.

So this appears to be a half-gigabit router, not a gigabit router.

Latest fimrware and factroy reset but still the same speed?
When it's connecting to modem via a cable on the same device, it's 900+Mbps but it's 4-500+Mbps when it's connecitng to Archer C5400 V2?
Make sure there is only one device which is connecting to the router and there is no other application running when you test speed.

Both were version 2.0 with the latest firmware. I never tried a factory reset - but that should not be neccessary. The first was updated to latest firmware, the second already had the latest.
