Exploring Maximum Speeds on Cat 5e Cable with FTTH, TP Link Switches and Huawei Router

For several years I have FTTH internet with 120/12 Mb UL / DL speed. The connection from the Huawei GPON router to two computers is via two Gig Link TP Link switches. The first splits the signal into four points, i.e. to the TV, Asus RT-AC1200G + wifi router, VOIP Gigaset telephone and the second switch, which again splits the signal to two desktops and a TP Link router for wifi. Both on computers and wifi over 5 GHz I have a transfer speedtescie reaching up to 200-230 Mb and after a while it drops to about 140-150 Mb. There is about 40 meters of gelled LAN cable to every network point bought about eight years of demo at dipol. I wonder how much I can get in this network when I change my supplier's speed? Apparently everywhere is connected on 1 Gb except VOIP phone, but this one has only 100 Mb port. Despite the gigabyte connection, can it be that already 200 or 300 Mb will be a problem and then only cable replacement remains? Currently, everything works without a problem.

For speed testing Instead of copying files, use the iperf3.exe tool.

Do I understand that I need to move one computer in place of the GPON modem and give the router along the way so that the copiers can see each other on the cable without patching? If so, I need to get a laptop, because moving the tin to the basement will be difficult.

Hey from my experience: I increased the connection in UPC from 60mbps to 250mbps and it turned out to be for wifi I pull max about 150mbps - despite the network connection showed that it connects elegantly 300mbit to the router.
The Ethernet 5e cable elegantly connects to 250mbps.

As for theories, eth 5e should pull this 1gibt calmly. However, you should use a ram-ram network speed test application to exclude transmission restrictions due to hard drive write capability.

These 300 are the sum of both ways. The radio changes and receives, so it goes out half.
