Setting up Airport Express as Access Point for Asus RT-AC68U
Looking for any advice on the following wifi router question(s)
My old Linksys router was having issues so I purchased an Asus RT-AC68U router to replace it. It has worse coverage than Linksys. So my IT at work suggested I get an Airport Extreme as an access point.
(Even though we use all Apple products in our house, it never occurred to me to purchase an AE in the first place. It never showed up in any reviews...)
I have now purchased an AE and tried to set it up this evening, wired into the Asus router.
Using the Airport Utility on my Mac laptop, Selected "extend existing network" and it only found my neighbors "base stations", presumably their Apple wifi.
I then tried "configure other", entered the Asus SSID login and password. It found the network but the little wheel just kept spinning...nothing happened.
So all you networking experts out there (not me for sure), what should I do? I literally wish to set this up and never think about it again for three years until something breaks. We are modest users with 10-20 wired and wireless devices. Options I am considering:
1. Try another method to join current Asus wifi network?
2. Swap Asus and AE to make AE primary router and Asus the access point?
3. Send Asus back and get 2nd AE, and never look back. Least preferred option but think I still can.
Thank you in advance for any assistance/guidance/opinions.
