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.

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:

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.

Hey everyone,

I’m having the same problem!! I upgraded and it’s making me think this is the worst iPhone (iPhone XS MAX 512gb) apple have ever made!! It’s meant to be the fastest phone on the market!! I got almost full 4G with my iPhone X and now I can’t even get 3 bars of 3G on the new phone! What the? I use my phone to make video calls to adoptees around the world and help connect adoptees world wide, as I am adopted as well, I came on the same plane as Saroo Brieley who made the movie “Lion” so my work is important with helping support other adoptees and I used your iPhones because they were the best to do it on!! I used my hot spot to my iMac to also video call but NOW I can’t do that because I have hardly any reception at all to do ANYTHING!! This NEW iPhone is the worst!!! Please please fix this problem quickly!!


Also please add an option to the phone where you can turn the SWOOSH sound OFF when you send a TXT message!! so annoying having to put your phone on silent every time I want to send a txt message without anyone else knowing!!! ADD AN OFF OPTION

(Other than that love you apple!) lol

Having similar issues with WIFI, speed cut in half from my router when doing fast.com speed test. Iphone XS Max loses internet connection via my router. In fact if I go into particular apps, twitter or Instagram it loses connection and goes to LTE mode but I'm still connected to my router. I have other devices that have a solid connection to my router without any issues so it's not the router.. I've rebooted etc, still having issues with my Iphone and keeping it connected to my network. A bug without a doubt Apple needs to take action. Phone reception is not the best, carrier settings updates but still half bar status, which is garbage for the amount we spent on this phone.

So I just got a call from someone saying they are from Apple and wanted to collect logs from my phones to help diagnose the problem. Anyone know if this is legit? They gave me a case number and sent me an email and I can see it matches up when I look at the support page online. But they called my home phone and I don't remember ever putting that down anywhere. It's possible that I entered in somewhere, but can't remember. The person on the phone said they needed me to install a certificate on my phone and send diagnostic information from both my phones to help narrow down the problem. If it is legit, super cool that they reached out already and it's a good sign that they are investigating it seriously. If it's not, beware of a scam going around 🙂.

They contacted me on Twitter last night and arranged for a senior representative to call this morning. He seemed to think that the new carrier update, 33.2 on att, might take care of the cell network connection problem. Because I’m not experiencing any functional issues on WiFi in my apartment other than diminished signal strength but no drop in connection or download speeds he did not think there was a problem there. However , again, I live in a one story small apartment. In a larger home I could very well have a significant problem. He plans to call again on Saturday to see what my cell connection experience is over the next couple of days.


They do do seem to be reaching out to people so hopefully a solution will be forthcoming.

This is so frustrating I have been on the phone with Apple 3x today I have the XS Max. I have been trying to make calls because they had me do a reset of my Network Settings. Whoever I speak with say they hear every other word then it says System Failure. I’m nervous because I don’t want the 15 day window to go by without being able to return it and I just received the box to send my 8 Plus back and I don’t want to send it back and get stuck with this. My husband has the same phone and his is just as bad as mine, only thing is his phone doesnt need to go back he was finished with his 2 year plan. I don’t know what to do, how long does it usually take for an update to come out.
