    Internet speed problem with 1 Giga broadband

    Happy holidays to all!
    I've recently been upgraded to a 1 gigabyte broadband connection. We have two PCs connected by LAN. One of them achieves 800 Mbps download and 100 Mbps upload, which is within the ISP parameters, while my Lenovo T450s laptop only achieves 100-450 Mbps download and 100 Mbps upload. I've tried different cables (both Cat 5e) to no avail.
    Any tips?

    Thanks in advance

    That laptop may not have a Gigabit LAN but only 10/100.

    Try TCP Optimizer and set it to: 100+Mbps - Optimal - Apply Changes.

    Thank you to both, I've checked and the laptop DOES have Gigabit Lan.
    I've discovered that the problem seems to lie with Kaspersky anti virus. If it's paused, I get full speed.
    I've tried TCP Optimiser but it actually slows it down (with Kaspersky paused).
    I'll see what Kaspersky says...
