Network Equipment Repair in Nairobi, Kenya

Downtime on networking or telecom infrastructure has a direct operational cost. Sinsal diagnoses and repairs routers, switches, and telecom equipment electronics at the component level, as an alternative to full-unit replacement where the fault allows it.

Service Overview

Switches, routers and access points are cheap compared with the downtime when they fail, but replacements can be slow, and failures often come in clusters after surges or when a model reaches end of life. Repairing the board returns equipment to service without a new purchase.

Sinsal repairs the electronics: power stages, PoE circuitry, interface and memory-related faults. Firmware recovery is available where a device will not boot. Brand names are used only to describe equipment that can be assessed, and no manufacturer relationship is implied.

Equipment We Work On

  • Managed and unmanaged network switches
  • PoE and PoE+ switches
  • Routers and routerboards
  • Wireless access points and controllers
  • Firewalls and security appliances
  • Media converters and optical-networking electronics

Typical Failures

  • Switch that does not power on, or reboots repeatedly
  • PoE ports that no longer deliver power
  • Ports that do not link or drop packets
  • Damage from lightning or mains surges
  • Overheated boards from blocked ventilation
  • Devices stuck in boot loops after failed updates

Diagnostic Process

  1. 01Identification of the device and the fault history
  2. 02Visual and microscope inspection for surge and heat damage
  3. 03Bench power-up with rail analysis on the main and PoE stages
  4. 04Oscilloscope and thermal checks on regulators and interface stages
  5. 05Hardware versus firmware determination

Repair Process

  1. 01Replacement of failed regulators, protection devices and PoE components
  2. 02Repair of damaged traces, pads and port connectors
  3. 03Firmware recovery where corruption is the cause
  4. 04Record of replaced parts

Testing and Validation

  • Rail verification on the repaired stages
  • Port and PoE output checks where a test setup is practical
  • Extended power-on run to confirm stability

Industries Served

  • ICT companies
  • Telecommunications operators
  • Data centers
  • Networking equipment distributors

What You May Receive

Diagnostic findings, Repairability decision, Repair record where work proceeds.

Warranty

Completed repairs are accompanied by warranty documentation. The cover, its term and its exclusions are written on the warranty document issued with the job, so they are agreed in writing for your equipment rather than assumed. Warranty applies to the repaired fault and the work carried out, not to unrelated failures elsewhere in the equipment.

Important Limitation

Sinsal repairs equipment hardware — firmware/configuration recovery is covered separately (see Firmware & Hardware Data Recovery) and network design, licensing, or carrier-side issues are outside this service's scope.

Frequently Asked Questions

Common Questions

Do you repair routers and switches, or only replace them?

Repair first where the fault is board-level and component-accessible. Assessment determines whether that's the case before replacement is the only option.

Can you work on telecom equipment as well as standard networking hardware?

Yes — the same component-level diagnostic approach applies to telecommunications equipment electronics, not only office/data-center networking hardware.

Have Failed Switches, Routers or Access Points?

Describe the equipment and the fault. Sinsal will confirm whether it is a fit for diagnostics and repair before any work begins.
