Fix Wi-Fi Extender Issue

I'm seeking an experienced network technician to resolve a connectivity problem with my TP-Link Wi-Fi extender connected to Airtel fiber. The extender drops connection after 5-10 minutes, despite using an Ethernet cable and having the latest firmware.

Ideal Skills and Experience:
- Experience with Airtel fiber networks
- Proficient in TP-Link configurations
- Strong troubleshooting skills (IP conflicts, DHCP settings, signal issues)
- Ability to provide step-by-step guidance or remote assistance

Please provide a solution to ensure a stable and continuous connection.
