// DATA & NETWORKING REPAIRS
Fault-finding and repair for data and networking faults across Hertfordshire and London — for dead network points, WiFi dropouts, and network hardware that's stopped working reliably.
The faults we're called out to most often.
Network switch or router faults causing loss of connectivity
Dead network ports or intermittent connections
WiFi dead spots, dropouts, or access points offline
Faults on existing structured cabling (Cat5e/Cat6)
Patch panel or comms cabinet faults
PoE (Power over Ethernet) devices not receiving power
Network faults affecting connected systems — phones, access control, CCTV
Slow or unreliable network performance traced to a hardware fault
Engineers work on structured cabling, switches, routers and wireless access points already installed on site, across the makes and models in place.
The same disciplined sequence, whatever the hour.
Describe the fault — no connection, WiFi dropping out, a dead port — and we'll advise what to check before we arrive.
Switches, cabling, access points and connected devices are checked in turn to trace the fault to its actual cause, then confirmed with one fixed price before repair work begins.
Repairs are completed and the network tested end-to-end before we leave, with a service or fault report provided.
Engineers check switches, cabling, access points and connected devices in turn to find the actual point of failure rather than replacing parts on guesswork.
Where a fault has taken down connectivity for critical systems — phones, access control, payment terminals — restoring a working connection is prioritised as the first step.
Network faults are diagnosed on the first visit, repaired on the spot wherever possible, and tested before we go.
You will receive a fault report or a service report describing the fault found and the work carried out, and a remedial quotation where further work is needed. See our documentation guide.
