Ethernet speed slower than Wifi connection

[kagaminelight]

Here's the situation,

My old router [TP-Link C1200 V1] was having constant rebooting and disconnecting from the internet issue. The condition worsen to the point where the connection would stay up at most for only 1 hour.

So I went and got a new router [TP-Link AC1200 Archer C6]
It's working fine and dandy with no disconnection whatsoever...

HOWEVER, the ethernet speed is slower now on my desktop than the previous router.

C1200: 550Mbps download, 40Mbps upload
AC1200: 80Mbps download, 95Mbps upload

Both of the routers - to my knowledge - have Gigabit port, and my desktop still has the same set of hardware.
- I have tried netsh winsock reset on CMD
- I have run the speedtest on another laptop

The AC1200 still provides more or less slower speed through ethernet.

SO, my question is whether the AC1200 is the problem?

Did you go into your desktop computer and reconfigure the network adapter to match the new TP-Link AC-1200?

Right click the network icon in the lower right screen corner. Select "Open Network & Internet settings".

Change adapter options.....

Did you disable WiFi while testing Ethernet?
Did you disconnect the Ethernet cable when running the WiFi test?
Have you tried another port on the router?
Try a different Ethernet cable

It's connected to Ethernet Network 3, similar to the previous router.

For both routers, the WiFi was enabled.
I did not disconnect LAN cable while doing the WiFi test.
Yes, all 4 of the ports.
I did, but same result sadly.

There is an issue when the upload speed is higher than the download.
When performing a speed test Windows might use all network devices with internet connection.
Get the latest drivers for your network adapter.
Uninstall the network adapter from device manager and reboot.
Allow Windows to find and configure your network adapter.
Disable WiFi and test LAN speed, if there are not improvements use the latest drivers for your adapter.
If there are not improvements, then try another cable.
Disconnecting a cable that was in a port for many years could damage the pins on the RJ45 connector.

Does the following link present the User Guide for your router?

The part about the pins on the RJ45 connector seems to be the case. Apparently all the cables that were hooked to the previous router was damaged. I went and bought new CAT6 cable and the speed is back to 550Mbps.

Just gonna have to replace all the cables. Thanks for the answers peeps

Very glad you got that sorted out, so you can enjoy your internet speed.
