1The Challenge

The office network was supporting more than 300 computers but had several configuration problems affecting stability. Key issues included: • DHCP service not consistently issuing IP addresses to client devices • DNS resolution failures affecting internal and external connectivity • Lack of proper VLAN segmentation within the network • Improper switch configuration and trunking between devices • Limited documentation of the existing network setup • High risk of operational disruption due to LAN instability Because internet connectivity was critical for daily BPO operations, the network had to be stabilized with minimal downtime for staff.

2Our Solution

CNS engineers performed a structured network recovery and optimization process to restore stability. Key steps included: • Full audit of existing router and switch configurations • Fixing DHCP configuration to ensure reliable automatic IP allocation • Restoring DNS functionality for proper name resolution • Designing and implementing VLAN segmentation for improved network organization • Correcting switch trunk links and port configurations • Testing connectivity across all workstations to ensure stability • Providing temporary WiFi coverage across the office during the reconfiguration process to reduce operational downtime • Creating documentation of the finalized network configuration for future maintenance The improved design ensured stable connectivity for all workstations while maintaining business operations during the upgrade.

3The Key Results

• Stable LAN connectivity for 300+ workstations
• Reliable DHCP IP allocation
• Improved DNS resolution and internet access
• Structured VLAN network architecture
• Minimal operational downtime during deployment
