Network design and installation
A business-grade firewall in place of the ISP router, managed switches and access points, and clean Cat6 runs to where you need them.
Networks, cameras, security and IT support for homes and small businesses, set up properly and documented.
I design and secure the network behind your devices: firewalls, Wi-Fi, separate networks for smart devices, monitoring that tells you when something's wrong, and remote help when you need it. Serving the ArkLaTex from Louisiana, on evenings and weekends.
Services
What I can set up for you
Security assessments
A scan of every device on your network, a plain-English report of what's exposed or outdated, and a prioritized plan to fix it.
Smart-home isolation and privacy
Cameras, vacuums, TVs and voice assistants on their own network, kept away from your computers, with ad and tracker blocking for every device.
Monitoring and alerts
Push or email alerts when the internet drops, a service goes down, a new device joins, or something on the network looks suspicious.
Home servers and self-hosting
Private photo backup, media and file servers on hardware you own, with secure remote access that doesn't open ports to the internet.
Security cameras
UniFi Protect camera systems that record locally on a UNVR, with no monthly subscription, on their own network away from your other devices.
Point-of-sale support
Support for Epicor Eagle point-of-sale systems: registers, receipt printers, workstation setup and the network they depend on.
IT support
Troubleshooting for PCs, printers, scanners and Wi-Fi, remotely through a secure session or on-site when it needs hands.
Recent project
Putting a shield around a family's home network
A busy household with more than 20 phones, computers, game consoles and smart gadgets, all sharing one wide-open network.
What the family gets
- Strangers' scans and known-bad websites are stopped before they reach the house.
- Smart gadgets can't snoop on computers or phones, even if one gets hacked.
- Fewer ads and trackers on every device, including TVs and tablets.
- Kid-safe search on the kids' devices.
- A text alert if the internet goes down or something looks suspicious.
- A one-page guide to how everything is set up.

How a project runs
Four steps, with nothing left undocumented
Assess
Scan and inventory every device, then list what's exposed, outdated or misconfigured.
Plan
Agree on networks, equipment and budget before anything is bought or changed.
Build
Stage the firewall and switches first, then cut over at a quiet time so nobody loses internet mid-task.
Hand off
Test everything, set up alerts, and leave you a cheat sheet of every address, rule and login location.
About
Hi, I'm Chris
I run CtrlAltFix LLC, an IT business for households and small businesses across the ArkLaTex. I bring deep, hands-on experience with enterprise Ubiquiti systems at scale: managed switching, wireless access points, UNVRs and Protect cameras across large, multi-building networks.
I also know Epicor Eagle point-of-sale systems inside and out, from registers and receipt printers to the network they depend on.
I build networks the way I build my own: segmented, monitored, and written down, so you're never dependent on one person remembering how it works.
