Question: 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

Wow i'm having the exact same problem. I hope they will fix this soon. I can't even browse on my phone because I have low wifi signal and low patience. I have an ipad and ipod and macbook right next to me and I am sitting right next to my router, yet my iphone xs max does not have full wifi strength and is super slow. Usually, I have all 4 service bars in my house and now i have 1-2. I still haven't seen three bars since I've had the phone. This is frustrating and this phone cost way too much to have these issues.

Same here on my XS (not Max). My X connected to 5ghz all the time, but even right next to my access point, the phone is kicking over to 2.4ghz. I suspect I'm going to have a tough time when I go to the office tomorrow and we have a 5ghz only network.

Having the same issues myself. Used to have full bars for wifi throughout my whole house with my X and now my XS Max is struggling to keep 2 bars. It's uper frustrating. Having the same issues at work 2. I still have my X and tempted to return this and pay TMobile the restocking fee.

Thanks but I'm familiar enough with networking to troubleshoot beyond that. I've tried all sorts of router options, but it's pretty clear there's some issue with the Xs because in the exact same conditions using the exact same router settings, the iPhone8 gets on average double the speed no matter where I'm at. It sounds like I'm not alone.


Doing some more testing, I found that I can actually force a speed drop of 2x to 3x in the Xs if I put my hand behind the phone. I had my phone propped up in one place and soon as I put my hand behind it the speed dropped about 2x. Take my hand away away, it goes back up. I was able to do this repeatedly and consistently. So it's more evidence that this is some sort of antenna/interference issue with the Xs. Antenna-gate repeat?


Also, fyi, that page has a section about enabling 802.11 n/ac on 2.4ghz and as far as I know, ac is only 5ghz...

I'm in the same boat, in places where my iPhone 7 Plus and iPad (2017) are able to connect to the 5ghz network just fine, the XS has trouble. It only shows two bars and doesn't maintain the connection that well. Really disappointing, for now I've switched to the 2.4ghz network on the XS. I hope Apple can fix this with a software update.

Same here, I have had an iPhone X before upgrading the Xs Max this past week and I have had significant degradation in both WiFi and Data speeds over T-Mobile. I can't figure out if its hardware related or the fact that there may be iOS software issues that hopefully Apple can fix.


I have dropped reception/signal now in places where I had no issues on the iPhone X.

Just adding my iPhone XS Max to the list. iPhone X in the same room getting much faster speeds on Wi-Fi and both on AT&T. On the XS Max, some web pages in Safari don’t even START to load for maybe 10-15+ seconds, and then once the page does start to load, it still takes longer than it should.

I was thinking it was an issue with some leftover junk in the backup from the X to the XS Max, but I’m not seeing any change after restoring and setting up as new. I even made sure to “forget” the XS Max in my router’s admin settings and in the xfinity iOS app. So it’d be truly like a new phone connecting for the 1st time when setting up as new. This is either a software issue that a 12.0.1 release could hopefully fix, or a hardware issue (yikes).
