iPhone XS Max Weak 5GHz WIFI Reception

I used to have full bars at my bed with iPhone X, now the Max only has 2. And it has trouble reconnect to the WIFI after airplane mode is turned on with WIFI turned on.

iPhone Xs Max, iOS 12, 64GB

For more empirical Wifi Data you can download the Airport Utility app (no need to actually have an Apple Airport), and follow the following instructions from https://support.apple.com/en-ca/HT203068 to run the scanner utility from your XS and other iOS devices at the same location to get comparative data.
The Wi-Fi scanner in AirPort Utility
Apple’s AirPort Utility includes a Wi-Fi scanner that logs the client’s view of the network. Administrators can use it to validate the client’s view of the network at a specific location.
For accurate results, use the Wi-Fi scanner on a dedicated device that’s the same model as the iOS client.
On your iOS device, go to Settings > AirPort Utility to turn on the Wi-Fi scanner.
User uploaded file
Next, open Airport Utility and tap Wi-Fi Scan.
User uploaded file
By default, Wi-Fi Scanner runs continuously. Use the slider to set a scan duration of up to 60 seconds.
User uploaded file
To start the scan, tap Scan. AirPort Utility lists all the SSIDs that it finds. This includes hidden networks, which appear as "Network name unavailable."
User uploaded file
The AirPort Utility scans all available bands at four-second intervals. Enterprise networks that have multiple access points are grouped by BSSID. The scanner shows information about:

  • SSID
  • BSSID
  • Last RSSI
  • Channel
  • Last Time Found

To view a trace log of the scan results for an SSID and BSSID, tap the SSID:
User uploaded file
The trace log shows the date and time of the scan, along with the channel and RSSI.
After the scan completes, you can share the results. Just tap the share icon (User uploaded file), then choose one of these options:

  • AirDrop
  • Message
  • Mail
  • Copy

AirPort Utility sends the results as a comma-separated list:
SSID, BSS, RSSI, Channel, time
"ACES", "18:64:72User uploaded file3:E9:40", "-57", "11", "12:02:03 PM"
"Cuba", "F8:1EUser uploaded fileF:F9:56:BC", "-53", "149", "12:02:03 PM"
"ACES", "18:64:72User uploaded file3:E9:50", "-63", "149", "12:02:03 PM"
"Cuba", "F8:1EUser uploaded fileF:F9:56:BB", "-69", "11", "12:02:03 PM"
"ACES", "18:64:72User uploaded file3:E9:40", "-67", "11", "12:02:07 PM"
The first line is a column header that shows the SSID, BSS, RSSI, Channel, and date fields. To analyze or chart the results, import the list into a spreadsheet or other tool.

I fully understand what you're saying. I suppose not all hosts do the same things. The hosts almost always do delete links from 3rd party publications that discuss issues such as this. We can all go out and find these articles, they just don't want them posted on their hosted forum. Believe me, I've had more than my share of posts removed over the years and most of them were my fault for getting too emotional.


I'll go back to my parents basement now. 👿 [I actually wish I could. I'm 63 years old and would give anything to be able to do so, but that house and my parents are long gone.]

Me and my husband are having the same issues, we had better reception with WiFi and LTE with his 6+ and my 7+. We’ve had these phones for a little over a week this is insane I’m ready to go to apple and tell them to take them back. They better get this fixed, I’ve been with Apple for a while and I would really hate changing to something else.

When you say works better than the XS are you referring to speed tests or real world use? I fear some here have worked themselves into a frenzy over inaccurate app based speed tests. I have not run a speed test on my XS Max. I don't see why I should. My XS Max is fast and keeps a great connection to the internet at all times. That's all I really care about. It just works. I don't need a speed test to show me my phone works fine.


I have no Bluetooth issues. If anything my range seems to have increased with this phone. I don't have dropped calls either, so LTE seems to work just fine on my phone.


I DO however, have the earpiece speaker intermittently not work issue. I put in a ticket with Apple about that. But I'm not very concerned about it, because I rarely if ever listen to the speakers on my phone. I have some very high end Bluetooth headphones, which is how I listen to music or watch videos.

I have a 2017 iPad and we still have one iPhone X in the house. My XS Max is faster than my iPad and on par or slightly faster than the iPhone X. But even if it was slightly slower, in real world use, it wouldn't bother me much. As long as my phone goes to the page I want, doesn't crash doing it, I can make and receive calls and Bluetooth works as it shoud, I'm fine. I don't measure my satisfaction in fractions of seconds.

You don’t need to fear that people posting in this thread are incompetent. You have no idea whatsoever how other people’s phones are and are not working. This issue is not about speed tests. At least not for me. My phone goes from perfect 5G wifi signal to dropped connection literally by moving a few feet between places. All my other iPhones (2x5s, 6, 7Plus and 8) keep their flawless 5G wifi connection in these “dead spots” that my Xs has.


Their is no need for you to doubt the experiences people are reporting. You’re wasting your time writing pointless posts and your wasting our time cluttering the thread. You’re also wasting Apple’s time, since they ARE reading this thread and they’re taking this issue very seriously, gathering log files and screen recordings.


If Apple has determined this is a real world problem by reaching out to people in this thread and conducting real tests, maybe you should consider it a real problem as well and stop patronizing the rest of us. It is enough of a hassle having bought a very expensive phone that doesn’t work the way it should without having to deal with people like you who seem to think they know more about my specific Xs unit than I do myself.

Man just ignore him, he may finally go away. now here comes another post where he will fight to assure your phone is fine and the issue is you and overreacting. I replaced my work phone yesterday (which wifi was better after the update) and Cellular connection got better but now wifi is again getting disconnected (and slow) did try a clean install on the new one and even tried 12.1 beta 3 with no success. Maybe continue replacing phones until you get a good one will be the answer

That's definitely interesting.


I've sent mine back within the first 14 days because I didn't want to keep it just based on the promise that it might work okay some day. Still, you're making me reconsider. Maybe there's been a bad batch among their initial production run. Either way, if this is a general problem, then it's surprising me that this doesn't seem to be affecting more people.
