I recently upgraded my cable internet speed from 800Mbps download to 1200Mbps.

But my download speed has not increased. It used to typically be 940Mbps and still is. However the upload speed has increased from 24 to 42 which seems correct.

The cable company says everything appears correct on their end.

The B760M Pro RSD4 mobo manual states it has a 2.5Gbps LAN. The modem/Gateway states it is 2.5Gbps. And I'm using a cat6 Ethernet cable to connect to a Windows 10 PC.

I changed one of the Network Interface Card Setting speed settings that I saw mentioned but it made things worse.

Any suggestions would be appreciated,
Thanks

This makes no sense. How on earth is only getting around 42 Mbps upload speed on a 1200 Mbps line normal? Unless you meant to type something else? For around a gig speed connection around 940 may indeed be normal. That's what I get on gigabyte Fiber, upload and download. One thing you can try is to check to see if you have Windows autotune enabled and then either disable or enable it and see if that makes a difference. Open an elevated command prompt and type in:

netsh interface tcp show global.

See if Receive Windows Auto-Tuning Level reads normal. If it doesn't and isn't enabled, then you can enable it by typing in:

Enable: netsh int tcp set global autotuninglevel=normal

If you want to try disabling Windows autotune, then type in:

Disable: netsh int tcp set global autotuninglevel=disabled

Reboot after each change and retest your speeds.

This only gives you the negotiated speed of your current network configuration (hence your ethernet port must be connected). The speed indicated also depends on the cable and the other end of the connection. This does NOT give the max supported speed of the NIC on your PC. For that, you need to look under Supported link modes also shown in ethtool.


mm@desktop ~
??ethtool enp8s0
Settings for enp8s0:
        Supported ports: [ TP    MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
                                2500baseT/Full
        Supported pause frame use: Symmetric Receive-only
        Supports auto-negotiation: Yes
        Supported FEC modes: Not reported
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
                                2500baseT/Full
        Advertised pause frame use: Symmetric Receive-only
        Advertised auto-negotiation: Yes
        Advertised FEC modes: Not reported
        Link partner advertised link modes:  10baseT/Half 10baseT/Full
                                             100baseT/Half 100baseT/Full
                                             1000baseT/Full
        Link partner advertised pause frame use: Symmetric
        Link partner advertised auto-negotiation: Yes
        Link partner advertised FEC modes: Not reported
        Speed: 1000Mb/s
        Duplex: Full
        Auto-negotiation: on
        master-slave cfg: preferred slave
        master-slave status: slave
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: external
        MDI-X: Unknown
netlink error: Operation not permitted
        Link detected: yes



you can try forcing the 2,5gbs speed, but if it's not hardware supported (cables, router) it wont work

sudo ethtool -s enp8s0 speed 2500 duplex full
