Attention I bought this cable (sold by Amazon) and it has never worked in 1000Mbps although it is mentioned everywhere he is Category 6 and it supports 1000Base-T (you can even read "Gigabit Ethernet" on the packaging). I hesitate in the future to buy the brand Lindy (as there is obviously no test or inspection of products) by Amazon against the service has not been a problem for repayment.
