Fix Business Wi-Fi Mesh System

I'm seeking a skilled technician to troubleshoot and fix our business Wi-Fi mesh system, which has stopped working properly. We have 4-6 nodes, but I'm unsure of the brand (possibly Google Nest, Netgear, or TP-Link). The nodes have stopped communicating with each other, leading to connectivity issues.

Ideal skills and experience:
- Familiarity with various mesh Wi-Fi systems
- Strong troubleshooting skills
- Experience with business network setups
- Ability to quickly diagnose and fix connectivity issues
