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.

interesting. so i have my genius bar appointment on sunday for my XS max and my wife's XS. do i just return them and go back to our 8pluses, or wait a few days to see if the software comes out and fixes. the 8 pluses needed to be returned by 10/5, so i'm thinking return the new phones and wait to see if a fix does indeed fix and then buy them again in a few months...as someone else suggested!

T-mobile user here and I upgraded from the 6S Plus to the XS MAX 256. I live in NYC and have noticed that it is EXTREMELY difficult to get service back when I enter subway stations.



In the subway tunnels, it's pretty typical to not have service but all the stations are wired for cell service. When I get to a subway station, we'll pull in, stop and be pulling away by the time I get any signal at all. And, by that point, it doesn't matter. On my older phone, it would pop up as soon as you entered the station.



Also, I live above ground and when i get there, it takes a very long time to get signal back after coming out of the tunnel. We're usually pulling away from the first stop before I even get signal back.



This is ridiculous!!



Side note - no WIFI problems, though, that I've experienced. It defaulted to my home 2.4 signal but I just removed that from memory and now it goes to the 5.

I’m giving them until the end of day Tuesday. And then I’m calling the tech back that called me. I’ve got his personal line from the email he sent me about my open case. I understand the backlash here. These phones aren’t cheap! But I also understand software updates, and troubleshooting, having worked in IT for about 15 years. People want a fix ASAP. But sometimes the fix that’s needed just can’t be fixed ASAP.

Same here. Still have my iPhone X not returned yet. It has all 5 bars on the Apple Router in all rooms on all devices (iPad Mini 4), but was I leave the room where the 5Gh router is at my brand new iPhone X’s MAX drastically drops to 1 bar in the doorway -leaving that room. I the attached hallway I then have no internet on the MAX but all other devises (iPad Pro 2, iPhone X, iPad mini 4, iPad Pro 10.5”) maintain 5Ghz all the way to the street and driveway of my house.


What’s going on here??

So yea...avoid the chat app!

The calls and emails I received from the two advisors I spoke to came as a result of posting here and on Twitter. Of course at that time my post here was only on the second page. Then the second person called because of my Twitter post to Apple Support. He had all the notes from my first conversaion and the case number. He was the one who told me they were trying to reach out to everyone who had posted and asking those with obvious issues to install the logging profile. In general I’m not seeing the issues many of you are posting about so we deferred going the profile route. I would have been happy to if it would have helped. But I’m assuming by now enough of you have done this and that they must have a good idea what’s going on. At the time I spoke to him he said they didn’t have a handle on it yet.


These are their premiere devices that have created a lot of publicity buzz, and I’m assuming a fair amount of profit. They will make this right. I can only see returning them if they are unusable as is for you and you have no other option. For those like me on the Apple Upgrade option returning them is simple but then you’ll have to start that process over again and may have to wait a good while to get the version you want.

I reported the issue to two senior advisers and was told the issue is bein escalated. I do notice a drop off in 5ghz reception or failure to connect to 5ghz in some parts of my house. No problem connecting to 2.4 or LTE. Quality of the voice reception is good. Since I upgraded from the X to the XS Max because of the larger screen, I will keep it and wait until iOS update.
