Use a Wi-Fi analyzer app to find the least crowded channel among and set it manually. Transition to Bridge Mode
To begin any firmware-related tasks, you must log into the router's management panel:
By default, the router uses auto-channel selection, which frequently drops connections due to local interference.

Next door, Jordan was stress-testing. He had four streams running: : Equipped with 4 Gigabit Ethernet (RJ-45) LAN ports
Can improve data handling efficiency, leading to potentially faster speeds and lower latency.
Jordan smiled. “The stock firmware is like a rental car with a governor on the engine. This ‘Extra Quality’ firmware is like tuning the ECU yourself. You get the performance the hardware was always capable of. But you also accept the risk. You become the engineer, not just the user.”
