Before you start running Cat6 cables through your walls, it's critical to plan and prep. This guide covers seven essential steps that will save you time, money, and prevent costly mistakes. From choosing the right cable type to calculating how much cable you'll need and ensuring attic safety—this prep work will set your Ethernet wiring project up for success.
Example: 9 ft ceiling × 2 = 18 ft ? Add 25 ft span = 43 ft ? Multiply by 2 drops = 86 ft total needed for that room.
Following these steps before starting your Ethernet installation will ensure a smoother, faster process—and help you avoid common DIY pitfalls.
What’s going on, guys? Welcome back to another video. I’m Mike from Ultimate Tech Hub—thanks for joining us. Today, we’re talking about Cat6 wall fishing—specifically, what to do before you start pulling cable through your walls.
There are four to five important steps (actually seven) that will save you time, money, and keep you safe. These are all based on questions we’ve received from previous wall fishing videos.
Step 1: Location Planning
Decide which rooms need Cat6 drops—bedrooms, offices, living rooms, patios, even bathrooms or front doors for Ring doorbells or security cameras. Write them all down.
Step 2: Choose Interior Walls
Always drop wires into interior walls to avoid fire stops found in exterior walls. Also, plan wire drops near devices like TVs, computers, or gaming consoles for convenience.
Step 3: Number of Lines
Don’t drop just one wire. Drop two or three. Use the third as a backup or for future additions. Behind the wall, just leave it coiled until needed.
Step 4: Central Hub Location
All wires must meet at one location—ideally where your modem, router, and network switch are. Many new homes have a structured wiring panel in a closet or garage.
Step 5: Cable Measurement Formula
Use ceiling height × 2 + distance to hub × number of drops. Example: 9 ft ceilings × 2 = 18 ft, add 25 ft = 43 ft × 2 drops = 86 ft needed. Round up for safety.
Step 6: Cable Type
Use Cat6 riser cable—it’s bendable, durable, and future-proof. Cat6A has higher bandwidth but is harder to work with. Avoid Cat5e unless budget is tight.
Step 7: Attic Safety
Only go in your attic if you’re confident. Walk only on rafters. Bring lighting, wear a mask, and never work in high heat. Spring or winter is ideal. Tell someone you’re going in, and take breaks when needed. Be safe up there!
