Will there be a slow down if I plug cat8 cable into a cat6 wall Jack? I am moving and will be running a hard line from the router in the middle of the house to my new office on the side of the house through the attic. Im under the 100 foot limit if cat8 but don't want to lose any speed. Finding cat8 wall plates/jacks seems to be difficult. Was planning on using female to female connections for ease and to not just have a hole in the wall with the wire running through it.
