Transfer rates on LAN are insufficient, lagging at 5 MB/s or below.

Keep all devices with offload enabled; they act as hardware boosts and lower CPU load via the driver. Confirm jumbo frames aren't active. Temporarily turn off power-saving or green Ethernet features—they save about 0.2-0.5 watts during normal use. Review your power management settings (battery and always on) and try disabling power saving for network cards or PCI-E devices, since the network card is a PCI-E device. Turn off wireless completely during transfers, as your traffic might be routed over Wi-Fi instead of cable. Verify the network cable is intact, and check the laptop's jack for any bent or misaligned contacts (there are 8 spring pins that could be damaged). Consider switching to a different driver for the laptop network card if needed, though it's unlikely to help.
Router performance is impressive—direct connections handle up to 5 MB/s, while 102 MB/s is definitely achievable.
It seems strange since the router should already include a Gigabit switch, making the connection unchanged. Double-check that both devices were connected at full Gigabit speeds. If not, consider upgrading to a more affordable Gigabit switch—though it might not be necessary.
