Networks and connectivity
Network and Wi-Fi management
A stable network is the foundation for computers, servers, phones, cameras and other technology. I design and manage wired and wireless networks around real operations, clear administration and secure separation of services.
When “the internet is down”, the cause may be anywhere in the network
Slow applications, Wi-Fi outages or unstable connectivity can be caused by cabling, an overloaded link, weak coverage, unsuitable routing or conflicting configuration. Without documentation and monitoring, these issues are often only worked around temporarily.
What I can cover
- New network design, reconstruction or takeover of existing infrastructure
- Management of routers, switches, access points and internet connections
- Wi-Fi coverage and separation of internal, guest and technology traffic
- VLANs, routing, firewall, VPN, remote access and site interconnection
- QoS, traffic management and analysis of bottlenecks or instability
- Documentation, configuration backups, monitoring and fault alerts
Typical situations
- Wi-Fi does not cover all areas or devices disconnect frequently
- The network grew gradually and its topology is no longer clear
- Guests, servers, cameras and normal users share one undivided network
- Branches or remote workers need secure connectivity
Measure first, change second
The design is based on device count, data flows, the physical environment and required availability. In an existing network, mapping topology, load and error conditions first helps changes address the cause rather than only the symptom.
Network infrastructure should be documented and its configuration backed up. This considerably shortens recovery after a failure or device replacement.
Outcome
The network becomes more stable, better separated and measurable. Administration gains a clear view of devices, configuration and dependencies, so future expansion does not have to be improvised.
