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’m no professional. I’m just saying that I’ve been digging hard for 2 weeks to find what is the culprit for this behavior on the latest iPhones. I’m hearing 50/50 by others and even professionals that deal with technology on a daily basis. Piecing things together to figure out what exactly is the cause of these widespread issues, only leaves me and others completely mind boggled. Honestly, I hope this isn’t hardware and the last thing anyone wants to hear is a recall. iPhone 4, unfixable. Hopefully not the same for XS and XS Max

I understand being mind boggled, but unless you're qualified to make the assertion this is hardware and can't be fixed by software update, you're not helping anyone. I don't believe for one second this can't be solved between Apple and the cellular providers by software updates. You and everyone just need to be patient. And stop running inaccurate App speed tests every few minutes and wringing your hands and fussing. Give Apple the time it needs and this too shall pass.

It’s not about being qualified. My statement was just an opinion because of the constant threads I’m coming across. I’m hoping this will be fixed soon and apple takes this seriously this time. As an ex marine, my days were hit or miss. Never knew where we’d go and end up. We just depended on our leaders. Well, same for this. Time will tell and our issues are in the hands of our leaders. Let’s see what happens in the future. Semper Fi to my bros

If you make a statement as you did that this can't be fixed by software, that's not an opinion, it's a statement. Don't "assume" Apple can't solve this. You know what happens when you "Assume!" I think you need to change your name to jerryguesses! 😉


Apple IS taking this quite seriously. They've reached out to a lot of posters in this and other threads on this very topic. They're collecting data and you can be assured the Apple Genius are burning the midnight oil on this for sure.


People just need to have a little patience.

Thanks:) The location I purchased at is high traffic. Ten days after release there was still a line for purchase of the new devices. I can only speculate the reason this device is working and the other one didn’t, but with all the logging Apple has been doing I’m sure they will get things straightened out. And many kudos to their support and being proactive.

I appreciate and thank you for serving in the Marines. But you won't see me in the jungle. I'm not a keyboard warrior either. I've just been here on this forum for several years, helping countless people through multiple launches and I know how Apple works when it comes to issues like this. Don't believe everything you read on the internet. There are those who say they can prove the earth is flat. Here's a hint. It's not.

Oct 6, 2018 6:31 PM in response to lobsterghost1

Yeah I definitely agree with that. 90% of stuff on the web is either true false or misleading. Then one person chimes in on something (apple haters) and makes it more confusing for us and to believe what is said. It’s definitely takes a lot of knowledge to work these issues, and ones like us on here, can only assist each other with their own personal experiences with the new flagships. I’m actually posting this on my XS. It’s currently reactivated and trying to live with these issues for now. Hopefully not for long. iPhone xs 64 gray by

Agree, whomever is "editing" these posts just leaves whatever it/he wants to and give a complete different message. Jerryknows I believe had every right to bring up different discussions, but some people here will just defend "helping countless people" whatever. As a shareholder I rather see apple continue having people like that, but as an iPhone owner this is a disgrace

Oct 7, 2018 3:28 PM in response to jesus253

I had been replying in another thread concerning the charging issue. The article on AppleInsider that I linked to stated that the software that shall not be named fixed the issue. All I did was put the link in and each post was removed. I thought that was a little silly since it was a publication, among several, that had a widely circulated report. Deleting my post seemed like closing the barn door after the horses have left.

Oct 7, 2018 3:35 PM in response to papjo

The hosts are just doing their job, which is to hold up to the terms of use (TOU) for the forum. In order to be able to post here, we ALL had to agree to them. If a post is edited or deleted, it's because the content was in violation of the TOU. Some people do post Nonsense, but that in itself is not a violation of the TOU. The people who are using beta software, signed a Non Disclosure Agreement stating they would not publicly discuss their findings publicly. They have their own forum to discuss the software. Discussing beta software in this forum is prohibited.


Hopefully you better understand how this all works.

Oct 7, 2018 4:28 PM in response to theozy

your...you are right, I do apologize for my previous behavior. I am on the same boat as everyone here, but I do have a XS (work only, personal had to return it) I guess I was a bit frustrated due to the fact that somebody was bashing another person on a statement, then asking for credentials to come up with such, just for them to make a statement when they are not apple engineers either. Everybody here is pitching in every single piece of information they can find, hence my visit to this forum as I am hopeful for this to be fixed.

Oct 7, 2018 4:30 PM in response to lobsterghost1

I do understand and I am a member of the beta test group but have not installed the recent iOS software so I have no knowledge of what it does. And I was not discussing it either, I provided a link to a publicly available article, one of many available by searching. I am well aware of what the hosts do but it’s curious that you could go to any Apple related site or publication and see the relevant information for yourself but the links get deleted here. Even though I have seen just today the software that shall not be named get named in many posts even in this thread. It’s all out there whether my links are deleted or not and no discussion has taken place here, that I’ve seen anyway. But it’s not my decision how the edits occur so I’m good.
