iPhone XS Max Me too - WiFi DL speed very slow on XS Max

I noticed slower DL speeds than I'm used to last night. Didn't compare it to other devices however. I will test again and compare to others this evening when I'm home from work.

Is this a XS Max only issue, or are normal XS running into this as well?

Front page of this website seems to indicate that XS has blazing fast wifi and LTE. Only Max users are having issues with wifi.
 
About 4GB of logs going to Apple for review. Hopefully they find something. Tech did wonder, maybe the battery tuning needs work. Maybe the phone is letting go of that 5GHz signal too quickly to save battery power. Again - just speculating/talking about it.....all this is new to him, so he's looking forward to getting my logs send to engineering.

Too be clear for any new people coming in.....for me at least.....the XS Max has no issue with speeds, as long as it's connected to the 5GHz band and getting a good signal. The problem is that something with the XS Max is having it fall back to 2.4GHz much quicker than previous devices. Basically falling back to 2.4GHz when it shouldn't. Yes there are plenty of cases where it SHOULD fall back.....but I think most people are seeing it fall back to 2.4GHz when there is no need.

I've been having a completely different issue where my speeds are just crippled. It stays connected to the 5 GHZ network with no problem bc I have turned off auto join for the other networks. But it's the speed that's inconsistent for me.

Interesting. I have noticed that the Data Rate (via Airport) does vary wildly compared my other devices. Other devices tend to have a higher data rate compared to my Max. Only problem is I don't have a internet plan high enough where that would matter.
[doublepost=1537804040][/doublepost]Looks like The Verge posted a story about this: https://www.theverge.com/2018/9/24/17895772/apple-iphone-xs-max-wifi-bad-signal
 
I am having the same issues as well. iPhone Xs Max. AT&T carrier v33.2.

Not only are my wifi speeds terrible (~10mbs according to Ookla speedtest) but my AT&T LTE speeds are horrendous as well (~3mbs according to Ookla speedtest). I couldn't tell if I was having an isolated issue but it's been like this since getting my phone on launch day.

After seeing an article on The Verge this morning about people having data issues with the Xs/Xs Max I figured I'd check the forums and it seems it's a good number of people having problems.
 
Alright, update. Came home during lunch. Compared multiple speed tests on different apps, and my XS Max is much slower than my fiancé’s 7 plus.

Her phone is pulling 230 down while mine is pulling 80-100 ish.

Same network, same server on Speedtest, etc etc.
 
there are wifi software bug with iPhone xs (max) + iOS 12. always prefer 2.4 ghz. first time connect to 5 ghz but when change one time to 2.4ghz..........always here. you need restart iPhone for few minutes with 5 ghz

I did also try 'forgetting' the 2.4 network for the second time yesterday, so far that is working today.

Back in failure mode. I have been watching my phone's scenarios carefully, here is what I discovered today. I have Google WiFi with 3 access points, basement, 1str floor, 2nd floor. I was out twice today, first time I came back, from the garage into the kitchen. It was connected to the basement point, 2.4. I figured, it was getting a remote signal at some point in the garage, grabbed the 2.4 as it was the best. But once in the kitchen, it did not go to the 5.0. So I went to the first floor point, about a foot away, and checked - it was now connected to the first floor point, but still 2.4 even though I was right next to it!

I then went out again - when I came back, I walked as fast as I could from the garage right over to the 1st floor point. I checked, it was connected there and at 5.0! So I left the phone in the kitchen, which seems to be a place where the basement point is the preferred connection. I eventually grabbed the phone, went downstairs, checked it, and sure enough it was connected to the basement and at 2.4.

So it seems that it connects to 2.4 from the fringe signal areas, as it probably should - I have read that 2.4 has wider range than 5.0. But once in the 5.0-stronger-signal-area, it won't move off of 2.4.

This is what I am seeing, see my updated info in post #62. The only thing I would add is per post #62, it's not clear which of two scenarios (below) I have, as it seems impossible to tell without logs/data analysis:

Scenario 1 - XS Max legit connects to 2.4 in fringe signal areas, but locks on and never goes to 5.0 when that should be preferred, or
Scenario 2 - moves off of 5.0 to 2.4 when it shouldn't, and stays there.

I would say today I saw scenario 1 in post #62, although in the past couple of days I could easily have seen scenario 2. @netnothing your post highlights scenario 2.

Thanks for the testing. Yeah I'm more seeing scenario #2 since in my test cases I'm only 20ft away from the Airport router, and there's only 1 wall in between me.

We have an Airport in the bedroom. Last night with testing, sitting in the bedroom is fine.....gets on 5GHz (after some help) and stays there. However, just simply going into the bathroom, which is in our room and shutting the door.....it will step down to 2.4GHz. This is maybe 20ft away and the door is one of those cheap, almost hollow builder grade doors.

So I think it's all a mix.

I reset network settings, and restarted the network. It came up connected to 5 GHz, but after a minute or two it was back on 2.4 GHz. An iPad, and 2 older iPhones in the house are solid 5 GHz, so it's not that the router doesn't support it.

Same here. Resetting network settings forces the XS to use 5 GHz for a bit. Then back to poor performance on 2.4 GHz. Only XS is affected other iOS 12 devices in house stay on 5 GHz.
 
I can’t get on - or stay on - my 5Ghz network.
AT&T store concierge told me to call Comcast.
AT&T phone support useless.
Opened Apple case - now in engineering’s hands.
Phone goes back Wednesday if they can’t sort it out.

(On XS Max) I know another user reported issues with download speeds using the XS Max on WiFi, I have the same issue I think. When I read his post, I tested mine and I was getting 80 Mbps d/l right next to an iPad getting 505 Mbps and an iPhone 8 getting 480 Mbps. So as he suggested, I rebooted - and I got 470 Mbps, so I wasn't worried - still probably doing stuff.

But I noticed this afternoon a picture has been stuck uploading to iCloud for over an hour, in Photos - so on a hunch I tested again, and back to 80 Mbps. When I powered off/on, brought up Photos, the photo had uploaded. But, in Speedtest it is only getting 87 Mbps. I forgot the connection and restarted, and I got 570 Mbps. But then, two more times, with the iPhone not obviously doing anything, it was back down to 80 Mbps. Other times, it is 480 Mbps - 570 Mbps.

I checked, and it is on a 2.4 GHz connection again. I think it slips from 5 to 2.4 periodically, I guess this is a bug?

If you have the Apple AirPort Extreme router do what I just did in Airport Utility. Give the 5GHz band a different name. Then log into that with your XS/XS Max phone. That way, on home network it will only use 5GHz band.

Partial solution till apple fixes software.
 
Tested again this morning. Other devices are getting 250-280 down. On the Max I’m getting 40-45.

Per google Wifi app my phone is connected to 5 GHz
[doublepost=1537877761][/doublepost]Is there any hope this is a software issue?

For me It is staying connected to wifi but with no internet access. I keep having to disconnect wifi in control centre and reconnect to get anything to work. This is on a 5ghz network.

I've tried a reset network settings and still. All looks fine, no internet until I disconnect. Very annoying. Same on the wifes XS (regular, not maxxxx). No problems with any other devices in the house.
 
Use EERO mesh at home so can’t separate SSID.

Currently have the following:

2 iPad Pro, 2 iPad Air, iPad 4, iPhone 6, iPhone 7+, Mac air, iMac, appletv - all are connected to 5ghz and are located in 7 different rooms.

2 iPhone XS Max’s - connected to 2.4ghz

I placed the iPhone max, iPhone 7+, and iPad Pro next to each other on the table. Turned off WiFi on all 3. Then turned WiFi back on. iPhone 7+ and iPad connected to 5ghz and iPhone Max connected to 2.4ghz.

I get close to 80mbs on 2.4ghz and 400mbs on 5ghz with the max so not a speed issue. The max just doesn’t want to connect to the 5ghz band on a reliable and continual basis.

Devices should be able to pick the better band on their own without separate SSIDs. This is a software bug with band selection. That being said, there's really no harm in an iPhone camping out on 2.4ghz, other than getting lower Speedtest results. I suppose it would be slower during the initial setup and downloading of apps, but otherwise you won't notice the difference.

The issue is, "iPhone Xs max antenna is not able to generate enough power to sustain latching on to 5 Ghz when signals are weak. And that's why its latching to 2.4 Ghz."
