We recently carried out a network service and troubleshooting job for a client in the Puchong area, after the office experienced serious issues with their LAN (Local Area Network). Despite having a stable internet connection, the team faced interruptions when using wired devices such as desktop PCs, printers, and local servers.
The Problem: LAN Network Not Functioning Properly
The client reported:
- No internet on PCs connected via LAN
- Inability to access shared drives and local servers
- Frequent disconnection from IP phones
- Network printers showing “offline” status
Although their Wi-Fi was working fine, the wired LAN network was down, affecting core business operations, especially in departments relying on desktops and internal systems.
Our Solution: Step-by-Step Network Troubleshooting
Our team conducted a comprehensive LAN network check and service, which included:
✅ Testing individual LAN ports and wall sockets
✅ Inspecting patch panels, network switches, and routers
✅ Checking and replacing damaged or loose Ethernet cables
✅ Reviewing switch configuration for VLAN or IP conflicts
✅ Ensuring DHCP and IP address assignment was functioning correctly
What We Found
After a full inspection, we discovered:
- One of the main network switches had failed, resulting in no data transfer through LAN ports
- A few LAN ports were miswired during a previous renovation
- Some Cat6 cables were deteriorated and causing signal drops
- IP address conflicts were affecting device communication
What We Fixed
🔧 Replaced the faulty network switch with a new, high-performance unit
🔌 Rewired and labeled several LAN ports correctly
🧰 Upgraded old cables to Cat6 for faster, more stable connectivity
🖧 Reconfigured IP settings for better device management and reliability
The Result
After the service, all LAN-connected devices were back online—stable, fast, and fully integrated with the internal network. The client now enjoys:
- Reliable LAN connectivity across the office
- Seamless printing and file sharing
- More efficient day-to-day operations
