So i had tried 2 way to connect output lan rj45 cable from tplink Archer C1200.
tplink Archer C1200 LAN port----cat5 2 meters lan cable----dlink 4-port switch----generic white color 15 meters lan cable---desktop pc.
tplink Archer C1200 LAN port----cat5 2 meters lan cable----dlink 4-port switch----3.3 meters lan cable----desktop pc.
Im signup 30M unifi package.tm speed test site show download=34M , upload=10M when used wifi pci card. dlink 4-port switch used because 15 meters lan cable fixed and tie on the wall was not long enough connect to tplink Archer C1200 lan port.
Here are the result:
First connect way---download speed=10M , upload speed=10M .
Second connect way---download speed=33.5M , upload speed =10M .
The culprit was the generic white color 15 meters lan cable caused download speed drop to 10M....lost 24M download speed.Found only 4 small core wires inside the lan port head.Others lan cable got 8 small core wires inside the lan port head.
I need 17 meters length lan cable. I want cat.6 cable.
My question is....if i buy quality 20 meters cat.6 lan cable , will it cause download speed drop again ?
Shouldn't be. Cat 6 should be good for 1gb for 100m. A good real Cat 6 cable of course.
