Networks and network security · Southern California and remote
Networks that stay below the stall
Wi-Fi, wired networks, and network security for homes and small businesses, designed from measurements instead of guesses. Every project ends with a floor plan, a network diagram, and test results you can read.
- -67 dBmor stronger at every spot you actually use, on 5 GHz
- 60%or less airtime load at the busiest hour
- 1 cableper access point, wired back to the switch
What I do
Services
Most jobs start with a survey and end with documentation. The work in between depends on the building.
-
Home
Home networks
Coverage in the garage, the back patio, and the upstairs office. Cabled to where it matters, wireless where it should be.
Typical work: Ethernet to key rooms, access point placement, replacing struggling mesh kits, router and switch setup.
-
Business
Small business networks
Offices, shops, studios, and restaurants. A network sized for the staff you have and the ones you plan to hire.
Typical work: firewall and switching, staff and guest separation, point-of-sale and phone readiness, written documentation.
-
Wireless
Surveys and optimization
Signal measured room by room, channels planned for the building, interference found and removed.
Typical work: signal survey, channel and power plan, roaming and interference fixes, before and after speed tests.
-
Security
Segmentation and security
Cameras, smart devices, guests, and work laptops each get their own lane, so one weak device cannot reach the rest. Business security work is covered below.
Typical work: VLANs, guest networks, firewall rules, DNS filtering, firmware and patch review.
-
Cabling
Cabling and racks
Clean runs to every access point, desk, and camera, with every port labeled and every path documented. A licensed cabling contractor installs it under a separate agreement with you.
Typical work: Cat6A runs, patch panels, PoE for access points and cameras, labeled ports, tidy racks. I write the spec and verify the finished work.
-
Ongoing
Care plans
Someone watching the network after the install, and a person to call when something changes.
Typical work: scheduled firmware updates, remote monitoring, quarterly reviews, priority support.
Why wireless matters
Wi-Fi is the network now
For most homes and offices, wireless is the main connection. Phones, tablets, and many laptops have no Ethernet port at all, and the rest are usually nowhere near a wall jack.
- Laptops
- Phones
- Video calls
- Smart TVs
- Doorbells and cameras
- Thermostats
- Printers
- Handheld scanners
- Door locks
Everything on this list shares the same radio airtime. More devices on the same airtime means the network has to be designed, not just plugged in.
Work happens on video
Video calls and cloud apps need steady throughput and low delay. A weak or crowded signal shows up as frozen faces and dropped calls.
Buildings fight the signal
Stucco over wire lath, concrete, glass, and metal studs block or reflect Wi-Fi. A router in a closet cannot cover the building, whatever speed the provider advertises.
Faster internet does not fix it
A gigabit plan does nothing for a device in a dead spot or one that shares a channel with twenty neighbors. The limit is the radio link, and it is fixed with placement, channel planning, and access points wired back to the switch.
Wi-Fi planner · rough numbers in ten seconds
How many access points do you need?
Enter the space and the devices. The planner sizes the access points for coverage and for load, then plots your network on the curve above. The starting numbers are an example.
Enter 300 to 50,000 sq ft, 1 to 1,000 devices, and 1 to 50 access points.

Planning estimate from rules of thumb for 5 GHz at -67 dBm. A measured survey replaces these numbers.
Why network security matters
Every business is a target now
Attacks are automated. Software scans the internet around the clock for exposed services, weak passwords, and unpatched firewalls, and it does not check how big the business is. Small businesses get hit because their defenses are thin.
These are the things attackers look for first:
- Open remote desktop
- Default passwords
- Unpatched firewalls
- One shared Wi-Fi password
- A flat network
- No logging
Each of these is a configuration problem, and configuration can be fixed.
The office has no edge anymore
Staff work from home, apps live in the cloud, and guests and contractors join the Wi-Fi. A single firewall at the door no longer describes where the data goes.
A flat network turns one mistake into a full breach
On one shared network, a single infected laptop or hijacked camera can reach the file server and the point-of-sale system. Segmentation keeps the damage to one lane.
Insurers and customers now ask
Cyber insurance questionnaires and customer security reviews increasingly ask about multi-factor authentication, patching, backups, and segmentation. A documented network makes those answers easy.
For businesses
Network security
Small businesses get attacked because their networks are flat, unpatched, and unwatched. I apply the controls enterprises use, sized for a business with ten staff instead of ten thousand.
What you receive
- A findings report in plain language
- A ranked fix list with effort and impact
- Configuration backups and a change log
- A diagram that matches what is actually deployed
Assessments run only against networks you own or have authorized in writing, with the scope agreed first. I prepare the network side for audits such as PCI DSS and for cyber insurance questionnaires. I do not certify compliance.
Firewall review and hardening
Rule audit, exposed services, firmware, logging, and admin access, with a ranked list of fixes.
Firewall replacement and migration
Move from an aging firewall to a new one with the rules translated and tested, and a rollback plan.
Segmentation
Staff, guests, point-of-sale, cameras, printers, and smart devices on separate networks, with only the traffic each one needs.
Secure remote access
VPN with multi-factor authentication in place of open remote desktop and port forwards.
Wireless security
Per-user or certificate sign-in instead of one shared password, guest isolation, and a check for rogue access points.
Monitoring and alerts
Alerts for new devices, config changes, failed logins, and outages, with regular configuration backups.
Also available
Beyond the install
Work that follows naturally from the main services.
Internet failover
A cellular or second-provider backup, so card readers and phones keep working when the main line drops.
Short-term rental networks
Guest Wi-Fi that survives turnover, with remote reset and a separate lane for smart locks and cameras.
Home office hardening
Work laptops kept apart from smart TVs and game consoles, with VPN-ready firewall rules.
Private servers
NAS and virtualization hosts for photo backup, media, and home automation, set up and documented.
Network audits
An inventory, a diagram, and a one-page report on what is exposed, outdated, or misconfigured.
Smart home foundation
A network that lights, locks, and cameras can depend on, with devices grouped by what they need to reach.
Platforms
Gear I work with
I recommend what fits the site, the budget, and whoever will manage it afterward. I have worked with all of these, commercial and open source, and I will tell you when the cheaper option is the right one.

How a project runs
Process
Five steps, in this order, on every project.
- 01
Scoping call
A short conversation about the space, the people using it, and what is going wrong today. You get a written scope and an honest answer on fit.
- 02
Survey
I walk the space with measurement tools, record what the building does to Wi-Fi, and mark where cable can run.
- 03
Design and quote
You receive a floor plan with access point locations, an equipment list, and a written quote for my work. The licensed cabling contractor quotes the cable runs separately. Nothing is ordered before you approve it.
- 04
Installation
The licensed contractor installs the cabling and bills you directly. I configure the network and check that every port is labeled and live.
- 05
Verify and hand over
Signal and throughput tests at every mapped spot, compared against the design targets. You keep the results, a network diagram, and a credentials sheet.
Questions
Straight answers
Is a mesh kit enough?
In an apartment or a small open home, often yes. In a larger or older house with cable access to each floor, wired access points are usually steadier. The survey settles it with measurements.
Do I keep the passwords and equipment?
Yes. You get an admin account, a written credentials sheet, and a network diagram at handover.
Can you fix only the Wi-Fi?
Yes. Many problems come from placement, channels, and settings, and need no new cable.
Do you run the cable yourself?
Cabling is installed by a licensed contractor I work with, under its own agreement and invoice. I design the layout, specify the cable, and verify the results.
What does a security review cover?
Firewall rules and firmware, exposed services, segmentation, remote access, and wireless settings. The scope is agreed in writing before anything is scanned, and you receive a ranked list of fixes.
Where do you work?
On site across Los Angeles, Orange, Riverside, and San Bernardino counties, centered on the San Gabriel Valley. Security reviews, network design, and care plans are also delivered remotely to businesses anywhere in the US. On-site work farther away is available by arrangement, with travel billed. Cabling is always installed by a contractor licensed in the state where the work is.
