Wondering why your netgear wifi extender not connecting to internet? It generally occurs due to the unstable power supply, low signal strength and ISP outages. Also, recheck your login credentials. Additionally, update the firmware. If the problem persists, power cycle or reboot your extender. If a technical glitch interrupts the work, perform a factory reset on your extender. This will reset the device. Afterwards, you can reconfigure it from scratch to fix the connectivity issue.
