hello

I am using two range extenders connecting to the same router.  They both have different SSIDs, and different to the main router SSID.  

Sometimes, the wifi to one of the extenders drops and to get it back on, I have to restart the other one.

I tried fixing this by assigning a manual IP address on one of the extenders, different to the other one, but no luck

Can anyone help to stop this from happening?

Thank you
