Extender from Linksys Won't Stop Blinking. Now what? Your Linksys extender has malfunctioned, either in terms of hardware or firmware, if you notice it continually blinking.
Ensure the extender is turned on and plugged into a power source. After then, confirm that the equipment is not broken or damaged. Now, make sure there are no symptoms of deterioration on the ethernet wire that connects the extender to the PC. Additionally, the ethernet wire that connects the modem and router should be in perfect condition. Always keep your extension away from heavy walls and home appliances. Continue with the reset process if there is no other way to resolve the problem.
