Strange problem about Ethernet speed: recently we bought an i7 core computer running Win7 64 bit with an onboard Gigabit Ethernet controller (Realtek PCIe Gbit Ethernet Family controller).
Connecting this new fast pc directly to our brand new ASUS Gigabit Ethernet router via CAT6 cable(!) shows up the adapter status (see picture attached) only 100mbit, while the router is capable of 1000 mbit. More facts:
- Connecting an 8 year old IBM notebook with gigabit ethernet to the same cable end shows 1.0 Gbit connection in its adapter status.
- Speedtest.net shows 35 mbit/s down on the new computer
- Speedtest.net shows 78 mbit/s down on the old rusty IBM notebook.
- We have an 120 mbit down internet connection, which we we truly receive on another pc (also directly connected to the router)
How to get the 1.0 Gbit going in the new pc ?
