Finding the cause of slow, patchy or dropped connections, dead spots, and devices that cannot reach shared resources.
Network & Connectivity Support
Office Network Support and Troubleshooting
A slow or unstable network affects everyone at once. ItCityHub supports the wired and wireless networks that small and growing businesses depend on, from diagnosing a single dropped connection to configuring routers, switches, access points and VPNs.
What we help with
Routers, switches and access points
Configuring and maintaining office networking hardware, including firewall rules, port forwarding and guest, VoIP and corporate network separation using VLANs.
TCP/IP, DHCP, DNS and connectivity
Fixing address conflicts, name-resolution problems and misconfigured network settings that stop computers and servers from connecting.
VPN and remote access
Site-to-site and client VPN configuration so staff can reach office systems securely from home or while travelling.
Network documentation and monitoring
A written record of how your network is built, and monitoring set up as part of an agreed plan, so problems are easier to spot and fix.

Frequently asked questions
Do you support MikroTik or Cisco equipment?
Yes. We configure and support MikroTik routers, Cisco switches, TP-Link Omada and Ubiquiti Wi-Fi, and Fortinet or Sophos firewalls, including multi-WAN failover, VPNs and access controls.
Can you fix a network problem remotely?
Often, yes. If a device on your network is reachable remotely, we can diagnose and change settings without a visit. A broken cable or a failed device still needs someone on site.
Can you document our existing network?
Yes. We can record your devices, addressing, VLANs and key settings in a clear document that you keep.
Is network monitoring included?
Monitoring can be part of a managed plan. What is monitored, and how alerts are handled, is agreed in writing.
