A little before & after cable management in my basement last weekend - in preparation for additional Wireless Access Points (eliminating dead zones).
Before: too many different folks working on this since we moved in, none of whom really gave a damn. And it worked so we left it and focused on more pressing issues.
After: It’s still kind of temporary as I will need to upgrade to a larger switch, and before I finish I intend to find some kind of rack for permanent mounting.
