Wiring home network patch panel (568A vs 568B)
Sorry if this simple answer comes across as too basic. But you really could get the decided by looking at your own setup.


Rewire at the end that has more slack cable in case you need to cut it off some to re-do it.
Evaluate if the wall jack is reliable if re-wired. It may need replacing if not reliable for multiple re-configurations.
Evaluate if the press fit connections on the patch block are designed for multi termination usage.
Work at the end that is physically easier to access.
