I am trying to setup this specific wifi extender but I can't. The main WIFI provider does not show up on the list. I did all the troubleshooting steps but still unsuccessful. For background, I changed to new ISP, on my prev ISP I was able to connect it and it works fine, but when I am trying to set it up on the ISP... it won't go through. The WIFI/ROUTER does not show up when I try to connect it.
