Business Network Engineering | MD, DC & N. VA

Sound familiar?

If you have said any of these, we should talk.

From a one-person office to a growing team, these are the network problems that come up most often. Pick a category, tick what sounds like you, and we will start the conversation there.

“Our Wi-Fi drops in the conference room and during video calls.”We survey the space and place access points where people actually work.
“Everything crawls when the whole team is in the office.”We find the bottleneck: the internet link, the switch, the Wi-Fi, or the setup.
“Our internet goes down and we cannot tell if it is us or the provider.”We test the line, the router and the setup, so you know what to tell your provider.
“Our equipment is a mix of old consumer routers and switches.”One set of business-grade equipment, configured to work together.
“Staff working from home cannot connect reliably, or we opened ports to make it work.”Secure remote access with a VPN or zero-trust tool, not open ports.
“Nobody has looked at our firewall since it was installed.”A review, then rules written for how your business actually works.
“Our network closet is a tangle of cables nobody dares touch.”Clean, labeled, tested cabling and a tidy rack.
“Our IT person left and nothing was written down.”A diagram, address plan, and settings on paper for whoever comes next.
“I could not tell you what is connected to our network.”We map it, separate it, and document it, so you can see what is there.
“Customers and guests use the same Wi-Fi as our business computers.”Guest access is kept apart from your business systems.
“We are moving or opening an office and need the network ready on day one.”Design, installation, and testing planned around your move date.
“There are dead spots: no signal in the back office or the warehouse.”Coverage planned room by room, with access points placed on purpose.
“Phones and laptops keep disconnecting as we walk around the office.”Roaming and channel tuning so devices move between access points smoothly.
“Printers and scanners keep dropping off the network.”Stable addressing and a network layout that keeps shared devices reachable.
“We keep getting IP conflicts or running out of addresses.”A proper address plan and DHCP setup.
“File transfers to our server or storage are painfully slow.”We check cabling, switch ports, and the storage path to find what is holding it back.
“Video and phone calls sound choppy.”Voice traffic given its own path and priority, plus Wi-Fi fixes where needed.
“We pay for fast internet but never get close to it.”We test each step from the provider to the device to find where the speed is lost.
“Everyone shares one Wi-Fi password, and former staff still know it.”Separate networks and a password plan, so access can be changed without chaos.
“Cameras, printers, and smart devices share a network with our computers.”These devices are placed on their own segment, away from your business data.
“We had a security scare and are not sure what is actually protecting us.”A review of what is protecting you today, with written priorities.
“Our router, firewall, and switches have not been updated in years.”A firmware and configuration review, with a safe update plan.
“Our second location cannot reach the main office network.”A secure link between sites that fits your setup.
“I travel and need to reach my files and systems safely.”Secure remote access that works from anywhere, without exposing your network.
“If our server died today, we would be down for days.”Virtualized servers with tested backup and a written recovery plan.
“Our server hardware is old and nobody wants to touch it.”Planned migration to current virtual infrastructure, with minimal downtime.
“We back up our data, but nobody has ever tested a restore.”Backups that are tested, with a restore procedure written down.
“We keep running out of storage and do not know where it goes.”A storage review and a growth plan.
“We are unsure about our virtualization platform and its costs.”A neutral review of VMware, Proxmox, and other options for your workload.
“We need more network ports, or moved desks and have no jacks.”New drops and expansion of your existing wiring.
“Cables are old, damaged, or unlabeled, and we get random link problems.”Testing, certification, and replacement of bad runs.
“I am the IT person by accident and do not have time for this.”We take the network work off your plate, and hand it back documented.
“Every fix is a patch, and nobody knows why it keeps breaking.”Root-cause diagnosis with findings written down.
“We do not know what to budget or replace next.”An assessment with a prioritized, plain-English roadmap.
“My home network is whatever my internet provider handed me.”A proper router, Wi-Fi, and settings for a home office.
“My family's devices and my work computer share one network.”Work and personal devices separated, so one cannot affect the other.
“Client video calls freeze when someone else is online at home.”We find what is limiting the connection and fix the setup.
“New printers, cameras and devices keep causing network problems.”Each device goes on the right network with the right settings, written down.
“We give vendors and contractors remote access and do not know what they can reach.”Access limited to the systems each one needs, with a way to switch it off.
“We are buying a new server and do not know what size we need.”Hardware sized to your actual workload, with room to grow.
“After a power outage, nobody knows what to start first.”A written shutdown and start-up order, and a UPS sized for the equipment.
“We keep adding small switches because we run out of ports.”A proper switch layout sized for your devices, with room to grow.
“Our cameras, phones and access points need power but we have no PoE.”Switches with the right PoE capacity for the devices you plan to run.
“We do not know where our equipment logins, warranties and provider contacts are kept.”One written record of equipment, accounts and provider contacts.
“We are moving to a new office and need the network planned before move-in.”We plan the cabling, Wi-Fi and firewall with you before move-in.
“We are adding people and the current setup will not keep up.”We check what the network can handle today and plan the growth.
“The landlord or a contractor gave us a cabling quote and we cannot tell if it is right.”We read the scope with you and point out what is missing or not needed.
“We need to choose an internet provider for the new space.”We explain what each offer means for an office of your size.
“We pay for a fast plan but never see those speeds.”We test at the router and inside the office to see where the speed is lost.
“We want a backup internet line but do not know if it is worth it.”We explain what a backup line covers and what it does not.
“The provider says everything is fine on their side.”We give you test results from your side, so the conversation with them is factual.
“We received a proposal and want someone independent to read it.”We read it with you and flag what is unclear, missing, or too big for your office.
“Our IT person left and we do not know how our network is set up.”We map what is there, so you know what you have and what needs attention.
“We have a limited budget and do not know what to fix first.”We rank the issues by risk and cost so you can decide in order.

More about our work and experience

Engineer-led

The engineer who designs your network stays with it through build and handover.

Plain English

You get clear recommendations, including what is not worth buying.

Documented

Every project ends with a diagram, an address plan, and recorded settings.

Vendor-neutral

We recommend what fits your environment and budget, and work with equipment you already own where it makes sense.

What it costs you

Small network problems get expensive quietly.

Lost time

Staff wait on slow files and dropped connections, and then wait again for someone to look at it.

Lost business

Choppy calls and unreliable connections are visible to your customers, not just your team.

Hidden risk

Unknown devices, default settings, and no recovery plan are easy to ignore until the day they matter.

How we fix it

Four steps, in this order.

Assess
We review your site, devices, and pain points before touching anything.
Design
You get a written plan with scope, hardware, and layout.
Install and configure
We build it, test it, and plan the cutover to keep disruption low.
Document and hand over
You receive the diagram, address plan, and settings in writing.

Questions

Questions we hear before the first call.

Short answers. If yours is not here, ask us.

Still have a question?

Send it with the form below, or call. You will get a straight answer, not a sales pitch.

Ask a question

Getting started

What does a network assessment involve?

You tell us what is going on and what you want to change. We review it, ask follow-up questions, and look at the network where that helps. You then get a written scope and quote before any work begins.

How much will it cost?

It depends on the size of the office, the equipment, and the work involved, so we do not quote from a price list. After the assessment you get the scope and price in writing, and nothing starts until you agree to it.

What happens after I send a request?

We read it, then reply by email or by phone, whichever you prefer, with questions or a suggested next step. If it is a fit, you get a written scope and quote before any work starts.

How we work

Do you work onsite or remotely?

Both. Troubleshooting can often start remotely. Cabling, rack work, and equipment installation happen onsite. We serve businesses in Maryland, Washington DC, and Northern Virginia.

Do you offer ongoing support?

Support after a project is scoped case by case, with the scope and response times agreed in writing. NETDZIN is not an emergency or 24/7 service, so we tell you plainly what we can commit to before you sign.

Will I get documentation?

Yes. Every project ends with a network diagram, an address plan, and recorded settings, so the network does not depend on one person's memory.

Can you work with our current IT provider?

Yes. NETDZIN can work with your in-house IT person, your managed service provider, or your other vendors when you need network engineering. We agree on who does what before work starts.

Can you troubleshoot a network you did not install?

Yes. Most troubleshooting starts with a network someone else built. We map what is there, test it step by step to find the cause, and write down what we found.

Equipment and vendors

Do I need to buy new equipment?

Not necessarily. We work with equipment you already own where it makes sense, and tell you what is not worth buying. When new equipment helps, we recommend what fits your environment and budget.

Which vendors do you work with?

We are vendor-neutral. We install and configure equipment from major vendors, including Cisco, Juniper, Ubiquiti, Netgate, and MikroTik, and recommend what fits your needs.
