Two of these one to replace the connection between the router and modem and one to hardwire the pc. I'm now able to get 4-500 mbps instead of what was 80-150(with a gig internet) for years. Using these on my new 10gb network.

Out of all my years in it and working with network cabling, these cables are not reliable. There is almost zero point in investing in the cat 8 standard when there is no practical home use for it in the foreseeable future.
