Yesterday my AC1900 WiFi extender started refusing connections to some devices on the 2.4GHz band. I can connect a couple Chromebooks but other devices (cell phones, Wyze cameras, and iPads) will no longer connect at 2.4GHz. iPads and phones will connect on the 5GHz band. This problem just started yesterday, had been working just fine. I updated the router's firmware and cycled power on all devices. Still can't connect devices that had connected just fine at 2.4GHz. Any ideas what would cause this?

The router is connected via WiFi to a router supplied by CenturyLink using the 2.4GHz band. This connection is working fine since I can connect to the Netgear extender using either band EXCEPT on those devices that are now failing to connect via 2.4GHz. The Netgear was setup so long ago I don't recall what method was used. However, the setup was successful, has been working correctly for years until a couple days ago. The devices that won't connect to the Netgear via 2.4GHz can connect to the CenturyLink on it's 2.4GHz band. This failure to connect issue with some previously connecting devices just started a couple days ago. Had been working fine for years.

When some devices work while others don't, my first move is to look at the wifi clients rather than the wifi source. Tried getting the refuseniks to forget the connection and rejoining the wifi?

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

What router is the EX7000 connected to? Did you setup the extender using wps or using the installation wizard?

Everything has been working fine on the 2.4GHz band for several years now. It just started refusing connections a couple days ago for connection attempts from about half of my devices that have been connection just fine for years. After several of my devices would no longer connect on the 2.4GHz band I updated the firmware in the router. No change, some devices will connect, others will not connect. Disabled the 5GHz band on the router. No change. On the router setup page there is no ability to reduce the number of clients so I should get 16 on each band. This limit was never reached, just some devices no longer connect at 2.4GHz. Looks like I have to buy a new WiFi extender.

well, you didn't answer any of the questions asked.
