There are so many ways to fix the Linksys WiFi range extender issue.
The central location of your entire house and office is the best to enjoy the fast internet speed in all directions. In case your extender device is placed closer to the metal or electronic appliances then immediately change the position of your extender because metal or electronic appliances absorb all the WiFi signals which come from the extender and router device.
Now, visit the web management page of Linksys Extender. After that, look for an administration option and then click on the software upgrade option. Now, if you see the latest version of the software file then download it on your computer. In the end, restart your Linksys extender device to complete the Linksys extender software upgrade process.
At the side or the back of the Linksys extender, you can see the reset hole button. Now, push the reset button by inserting a hairpin for 10 seconds. Now, all the Linksys extender LEDs will be turned off. As it means the extender is now completely reset.
Note: After resetting the Linksys extender do the Linksys extender setup process again.
