Network Infrastructure
Wired and wireless networks designed around how traffic actually moves through your business, not a generic template.
A network is infrastructure, not a checklist of devices. TCPGrid designs LAN and WAN topologies, VLAN architecture, and routing policy around the traffic patterns, failure domains, and growth plans specific to a site, then documents it so the next engineer who touches it isn't starting from zero.
Work ranges from single-site redesigns to multi-VLAN segmented deployments across routers, switches, and wireless controllers, with attention to what breaks under load and how to isolate it when it does.
What's included
Network design & topology
LAN/WAN architecture, IP addressing schemes, and routing design built for the site's actual growth trajectory.
Routing & switching
Configuration and lifecycle management of routers and switches, including redundancy and failover planning.
Wireless architecture
Enterprise wireless design covering coverage planning, SSID/VLAN segmentation, and roaming behavior.
VLAN & segmentation architecture
Logical network segmentation that separates traffic classes and limits blast radius during an incident.
Performance optimization
Identifying congestion points, misconfigurations, and topology issues that degrade throughput or reliability.
Troubleshooting & diagnostics
Structured fault isolation for intermittent connectivity, routing loops, and latency issues.
How we approach it
Assess
Map the existing topology, traffic patterns, and constraints before proposing any changes.
Design
Produce a topology and addressing plan sized for current load and near-term growth, with documented trade-offs.
Implement
Deploy changes in controlled stages with rollback paths, minimizing disruption to production traffic.
Document & hand off
Leave behind topology diagrams and configuration records, not tribal knowledge.
