I have had this Samsung Network extender in my house for about 8 years maybe. Haven't had a problem. I live in the mountains and don't get a good cell tower signal. My iPhone 8 all of a sudden - maybe since last update, not sure- decided it wasn't going to connect to the extender. I've taken it out where there is a cell tower signal, at my phone works. Right now when I'm at home, I can send and receive texts but cannot make or receive phone calls. I've talked to tech support and yesterday they did a trouble ticket and tried for several minutes to diagnose the problem. I did'n't know then I could connect to a cell tower some drive away though. Anybody else experience this? My wife's iPhone 5 works fine now with the network extender. Weird huh?
