How do i know that my extender is working fine?

you need to connect your mobile or computer with extender's network and check the internet access if yes that means extender is working properly.

If there is no network access on your extender network then restart your extender.

If you want good internet speed make sure extender should be 30 -35 feet near to the            main router.

After you are done with the setup, connect your devices to your extended network and see if you are able to go online and see the light on the extender it should be solid green.

if you see it, means the extender is working all good.

> connect your computer or smartphone with the extender's network and then check if you are getting the internet access on your device.
if yes ,then it means that it is working fine.
> If extender's network is not showing up on your devices then try restarting your extender and then check again
>connect your devices to the extender from the different range and check if its providing you better signal strength.
> In order to get good internet speed from extender, make sure your extender should be in 25-30 ft from the main router.

1) We’re basically testing signal strength Before & After right? So here we go:

2) Find the spot in your area that needed to be boosted in the 1st place (bedroom, upstairs, through a few walls, etc. We’re going to use an excellent built-in wireless checker avail in the last few releases of OS X.

2A: W/MacBkPro running 10.9+: With the Extender @:/OFF, 'Option-click' on the Wi-Fi icon in upper-right menu bar. There will be a drop down menu - select 'Open Wireless Diagnostics.’ It’s sorta a secret app! (I don’t know why..?) It’s located hidden inside /System/Library/CoreServices/Applications if you want to make it a perm addition to your desktop.

2B) Take a reading - it’s self-explanatory - but will give you a great overview.

2C) Plug in the ‘Extender’ - repeat reading/signal checking. If it’s setup right you should see at least a 10% or more difference. Can I suggest one more easy helper? Purchase larger/better antenna(s) for your base router - this can make a a tremendous difference on its own, and it’s usually less expensive than a plug-in signal booster.

2D) You can check signal with nearly any iPhone/Android setup as well. The signal checker program I use for both is ‘OpenSignal’ - it’s free, and it also checks 4G/LTE signals for all carriers…very, very handy.

Hope this helped
