Network repair . NYC and tri-state

Network repair for any brand, any layer.

Internet down, Wi-Fi dead zones, a slow network, a failed switch, or an ISP router swap that broke everything. We work every layer, from cabling and PoE to switches, Wi-Fi and the firewall, including networks we did not set up.

Every network problem lives somewhere in the stack.

Tap what you are seeing. We will show you where it usually breaks and how we fix it.

Nothing is reaching the internet. It could be the ISP, the firewall, the main router or the core switch.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
ISP outage or modem down Firewall or router failed Core switch failed
HOW WE FIX IT

We work from the ISP handoff inward: modem, firewall, then core switch, and get you back online first.

Everything connects, but it is painfully slow, or slows down at certain times of day.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
Network loop Bandwidth saturated Failing switch or bad cable
HOW WE FIX IT

We look for loops, saturated links and failing hardware, then fix where the slowdown actually lives.

Specific areas have no signal, or devices keep dropping and reconnecting.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
Access point in the wrong place Interference from nearby networks Too many users on one access point
HOW WE FIX IT

A quick site survey, then we move or add an access point, or tune channels and power on the ones you have.

A switch has died, some ports stopped passing traffic, or it keeps rebooting.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
Switch dead or rebooting Ports stopped passing traffic Firmware fault
HOW WE FIX IT

Replace the switch, move the dead ports or recover the firmware, depending on the failure.

Cameras, phones or access points lose power or reboot on their own.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
PoE budget exceeded Bad injector Cable fault causing voltage drop
HOW WE FIX IT

We measure the PoE budget and voltage, then fix the switch, injector or cable that is short.

One access point is dead or shows offline, and that part of the office lost Wi-Fi.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
PoE port or injector failed Firmware fault Access point failed
HOW WE FIX IT

We check PoE first, then recover the firmware or replace the access point.

A firewall change broke something, the VPN will not connect, or devices land on the wrong VLAN.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
A rule change broke something VPN will not connect Device on the wrong VLAN
HOW WE FIX IT

We audit the rules, VPN and VLANs against how the office actually works, then correct them.

The ISP replaced the modem or router, and since then things that worked do not.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
Firewall rules lost VLANs and reservations gone Port forwarding lost
HOW WE FIX IT

We restore the firewall rules, VLANs, reservations and port forwarding on the new setup.

Nobody has the admin password for the switch, the firewall or the Wi-Fi controller.

WHERE IT BREAKS
Cable PoE Switch Wi-Fi Firewall ISP
LIKELY CAUSES
Consultant kept the only login Staff member left Lost cloud controller account
HOW WE FIX IT

We recover access through the right path for that brand and hand the credentials to you.

Outage right now

Everyone down, or just some?

Everyone down at once usually means the ISP, the firewall or the core switch. One area or one group of users usually means a switch, an access point or a cable. We test the physical layer first, so you do not pay for guesses.

Note who is affected and since whenEveryone, one floor or one group tells us where to start.
Do not factory reset the firewallA reset can wipe the configuration we need to restore.
Photograph the modem, firewall and switchThe status lights tell us a lot before we arrive.
Brands we service 06

Networks we repair every week.

Dedicated pages for the platforms we see most across NYC offices and multi-tenant buildings, plus the gear that ended up in the closet anyway.

Any brand, even if we did not install it

You do not need the original IT vendor.

No admin passwordWe recover access on the switch, firewall or controller.
No documentationWe map the network and write it down for you.
Consultant gone or staff leftWe take it over, or work beside your IT consultant.

Most network calls are on gear set up by IT consultants who are no longer around, or by staff who have since left. That includes legacy unmanaged switches, pre-cloud wireless controllers, and consumer routers running commercial spaces.

UniFi Cisco Meraki Aruba Fortinet Linksys TP-Link Netgear Unmanaged switches Consumer routers

Network problems are often cabling or power problems in disguise. We test PoE voltage, cable continuity and link speed first, then move to the configuration in the same visit.

How we work 04

What a network repair visit looks like.

We work layer by layer, so you do not pay for guesses.

01

Phone triage

Everything down, just Wi-Fi, specific users, or after an ISP change. Five minutes on the phone tells us which layer and what to bring.

02

Layer by layer

Cable test, PoE test, switch link status, firewall logs, Wi-Fi survey. Physical to logical. The first 20 minutes is isolation.

03

Fix on the spot

Cable swaps, port moves, firewall rules, firmware and standard switch or AP replacements are same-visit. Specialty gear gets a workaround.

04

Test and document

Every affected user back online, speeds verified, firewall rules confirmed. Written summary for your IT or management file.

Older systems

Repair, or time to upgrade?

Consumer router, or real gear?

For a two or three person office, a solid consumer router may still be fine. With 10 or more users, PoE devices, VoIP or cameras, it becomes the bottleneck. We quote the upgrade honestly.

Working with your IT consultant

We often handle the physical and infrastructure side while your consultant handles the applications. Clean handoff and documentation on both sides.

Frequent questions 06

Network repair FAQ.

Yes, and it is one of the most common calls we get. ISP router swaps regularly break firewall rules, VLANs, DHCP reservations and port forwarding. Once we see the new network, we restore the rules, re-establish the VLANs and re-create the reservations.
Usually yes. Depending on the brand there are several recovery paths: a reset with the configuration restored from a backup, vendor support with proof of ownership, or a password reset over a console cable. The right path depends on how much configuration a reset would lose.
Sometimes. We survey first. A coverage gap may need an access point added or moved. Interference can often be fixed by tuning channels and power on the existing ones. Too many users on one access point means rebalancing. We tell you which it is.
Yes. We regularly handle the physical and infrastructure side while your IT consultant handles application-level work. Clean handoff, documentation on both sides, and we do not try to take over their relationship with you.
It depends on size and traffic. For a two or three person office a solid consumer router may be fine. For 10 or more users, PoE devices, VoIP or any real camera system, consumer gear becomes the bottleneck. We quote the upgrade honestly and tell you what you get for the money.
