Windows 7: PC LAN running slow

13 Jan 2016   #1

W7 64 bit ultimate
PC LAN running slow

Slow LAN speed on PC
I have a PC connected to a GigE Ethernet switch ( TP-Link TL SG108)
I also have several other devices connected to this switch ….. Particularly my laptop.
The switch then connect to GigE port on my BT Home Hub 4

If I test Laptop Wifi to Hub … download speed ~3.03Mbps
If I test Laptop wired to Ethernet switch … download speed ~3.03Mbps
If I test PC wired to Ethernet switch … download speed ~1.9 Mbps
If I test PC wired to Hub … download speed ~1.9 Mbps

I seem to be getting a 30% loss of throughput when I use my PC compared to Laptop.
Both Laptop & PC running W7 64bit - used in same room .. even interchanged Ethernet cable to check those.

Is there some config or similar on my Ethernet on PC that could account for this ?
I’m no LAN expert ……..

PC uses on card Ethernet port, no config all as standard ………. It’s a new good quality motherboard on a fast PC …

LAN says it’s a Realtekฎ 8111F, 1 x Gigabit LAN Controller …. Settings that I can find are:

Any suggestions ?
