That's interesting. What brand cables are you using? Strange that a network chipset can be affected by the brand of cables. What affects it? Aluminium, copper, resistance, impedance, conductance?

My 2 main computers are Realteks; Zotac Z77ITX, cheapo USB3 GBe for my MacBook. The MacBook is connected to a router using a Mediatek switch chip and the PC is connected to one using a Artheros switch chip.

This just made me realised that I don't know the brand of cables used in my house. Or I had forgotten. I must have specified something to the contractor. Must go check.

I think probably is aluminium which is not good in performance compare to copper wire. I dont think i can figure out the brand , i remember this cable just ordered almost 3 years ago from Taobao. Maybe i was being scammed 😧. I just know the quality of the cable is very cheap la , it just simply aluminium fiber.
