Anyone else having this issue? When I wake up the phone, sometimes it'll drop the wifi icon to LTE and then back to wifi, sometimes it'll remain on wifi, sometimes it'll remain on LTE. I've tried resetting my network settings and updating to IOS 12.0.1, this is so frustrating.

My 8+ did this after iOS 12 after a year of ownership and having no problems. My Xs MAX does the SAME thing leading me to believe it is not the phone but iOS 12. After 12.0.1 I haven't seen it do it yet on my Xs MAX. Was wondering if anyone else was having this happen to them too.

I'd take back my Xs MAX if it hadn't happened to my 8+ as well.

REALLY noticeable when reading in bed at night... watching that LTE / WIFI flip back and forth again and again. lol. Really hope they fix this by iOS 12.1 :)

Just checking but do either of you have Wi-Fi Assist turned on? It's at the bottom of the Settings -> Cellular page. Could be the phone is detecting the cell signal is better than your Wi-Fi signal?

I do have it on. Never had a problem with it until now. I’m 3 ft from a $280 router. Very possible. I haven’t been able to reproduce this on 12.0.1. But I’ll try turning that off to see if that does it. Totally forgot about that.

Honestly I still think 12.0.1 has WiFi issues. Maybe they are related and somehow because that's on it thinks WiFi is bad and leaves you on cellular?
 
My XS wouldn't stay connected to WIFI and now it seems to be better on 12.0.1.

Mine does the same thing, but mine isn't a "Max" model just the Xs

Probably. I noticed wifi bars would go down to 2-3/4 even sitting next to my router and then the LTE WiFi would flash back and forth repeatedly - like in the video. This happened on my 8+, Xs MAX - but 12.0.1 seems to have mitigated it some cuz I can't get it to happen again.

I can't get it to happen here at work so 12.0.1 seems to have "fixed" it for me.

If it happens again, I'll try turning off assist - that's probably what's turning on.

I'm connected to a 5Ghz wifi only.
 
My XS still drops wi-fi with the 12.0.1 update. I don't have a 2.4GHz network with the same SSID as my 5GHz network, so when it disconnects, it just falls back to LTE. I never had these issues with my 7 Plus. I think the XS just has crap wi-fi hardware.
 
Having this issue on my XS Max on 12.0.1. Tried resetting network settings. We’ll see if it fixes anything.
 
I don’t know if iOS 12.1 beta has anything to do with it but I haven’t had any WiFi connectivity issues on my Xs Max. Had to upgrade it the Max to the beta out of the box because I wanted to restore from backup.
 
Reset your network settings and then sign back in
[doublepost=1539152081][/doublepost]Doesn’t appear to be fixed Even after installing the update
 
My daily routine with my SE involves having the phone ask what network I want to join every hour or so. That's very annoying.

I also reset my network settings several times and restored my phone.
 
This seems to be an old age problem with iphones for years. My max does it sometimes. I have heard it's for saving battery power in standby mode. It's supposed to come back on when you get a notification but i can't say. Wouldn't be much good for wifi calling if there's a problem.
 
What version of iOS comes on a new iPhone? Just got a new iPhone XS and trying to migrate the data from previous phone during set up but the wifi keeps disconnecting whereas it is stable on old phone.

Edit: it was supposed to do that, since the Move to iOS app creates a private wifi connection. I was confused that it seemingly switched to 4G.
The iOS version installed was 12.0.1. Wifi seems stable for the moment.
