Recently, I bought a TP-Link AC1750 Archer C7, which has four Gigabit Ethernet ports (800 Megabits each), 1300Mbps 5GHz WiFi and 450Mbps 2.4GHz WiFi. I have connected my PC to the router by an Ethernet cable, and the link is shown that it is 1.0Gbps in Windows network. I have a FileZilla file server running on my PC.
I tried downloading a 4GB file from the server with my Mac Book Pro 2015, which has 802.11AC, and connected to the 5GHz network of the router.
Surprisingly, I only get 37.0MBytes/s of download speed. Shouldn't I be getting around 100MBytes/s of download speed?
I have my file on an SSD, which has a read speed of 100MBps+.
As I know the router has 1.7Gbps of total wireless bandwidth, and each Ethernet port has 800Mbps of bandwidth, I don't see any way why I am getting around 37MBps. Is it the cables? Even though Windows recognizes the link as 1Gbps, can the cable reduce the speed? I am using the cable that came with the router (CAT5).
As far as I know, only CAT5e or higher is compatible with Gigabit Ethernet. But here, as Windows shows that it is a 1Gbps link, is it really the cable or something else?
Can somebody please explain me this?
