How it works

Inspect and remove the old jack

We pull the plate forward, inspect the terminated cable pairs for correct color coding and any damage, and cut back the cable end to expose fresh wire.

Punch down and install the new jack

We use a punch-down tool to seat each pair correctly in the 110 keystone block to the T568B standard (or T568A if the rest of your home is wired that way) and snap the jack into the wall plate.

Test and confirm speeds

We plug in a cable tester, verify all 8 conductors are passing, then connect a laptop and confirm the port negotiates at the expected speed.

We can help

Problems we fix

Pairs crimped without being untwisted enough, causing near-end crosstalk that drops Cat6 speeds to Cat5e performance
T568A vs. T568B mismatch between the wall jack and the patch panel at the router end
Physical damage to the plastic locking tab that lets the patch cable fall out
Old Cat3 wiring behind the jack that can't support Gigabit regardless of the new jack

Good to know

Ethernet Wall Jack Repair in Charleston — FAQ

Why is my wired internet connection slow even with a new jack?

If the cable run uses Cat5 or Cat3 wire, the cable itself is the speed bottleneck. We can confirm the cable category and let you know whether upgrading to Cat6 would actually help your setup.

Can you install an Ethernet jack where there's only a coax connection right now?

We can install the jack and wall plate, but running new Cat6 from the jack to your router or patch panel is a separate cable fishing job. We can do both in the same visit.

What's the difference between T568A and T568B wiring?

They're two different pair color assignments for the same RJ45 standard. Either works fine as long as both ends of the run use the same standard. T568B is more common in North America.

Local context

Ethernet Wall Jack Repair across Charleston

Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
