iPhone XS Max Weak 5GHz WIFI Reception

To make it clearer, my phone does not work on the 5ghz in my house in the same space where older phones including the X worked. Simple as that!

That’s a respectable answer. I will agree with that. Splitting the networks was the only way to make it feel semi normal....for me at least.

Got to keep the pressure on - I can not even get Apple to exchange the phone...

Not sure how you came to the conclusion that 12.1 solved most people’s WIFI problems. I did not make a difference in mine and Apple did not claim it did.

It depends upon your router and various environmental factors.

I've posted this before, but this was a 5 GHz test run against an 802.11ac Time Capsule:

Me too!

This is my second phone and second or third SIM card. I’ve been through everything. I gave up. So I’ll live with a $1200 phone for now. No other options really.

Thank you, and please let me clarify that my reply about annoying people was not intented to you personally.

How’s today’s release of iOS 12.1.2 on your end? I was fine thru all of the 12.1.1 betas, but then issues returned on the official 12.1.1 release, and now seem worse on 12.1.2

Were you having issues before and the 12.0.1 update solve it?

I am experiencing issues as well with my Xs (non max) as well coming from the X. I have amazing wifi in my home. Never have had an issue with my phones until the Xs. Videos won’t play, pages won’t load etc. I still have my X and my husband still has his X. Neither one has any issues and they are both running iOS 12. Only issue is with my Xs. No resolution within the next few days and it’s going back.

I have a XS Max here in Switzerland. Had issue to connect to my 5Ghz network but I set forgot said and reconnect. All went OK. I also by default disabled wifi assist (poor wifi will make your phone switch to lte or cellular network)

I also did a speed test comparing my 7plus, same spot same date... The XS Max was like 8Mbit/s where the 7 plus was around 10Mbit/s.

I'm very curious to see if there is something wrong but at home I didn't saw wifi (have 2.4 and 5) issue.

Not a realistic comparison. iPhone 4 antenna bands were placed in the wrong place physically on the phone and there was no way to replace every unit sold. They did tweak reception with software and for most people, the issue was reasonably resolved and became a non-issue.

This is totally different. According to some of the best labs who have tested XS and XS Max, the Wifi and LTE speeds are faster and stronger than any phone out there. The problem is often in individual owner's hands when you take into consideration all the different networks and routers out there.

Apple has the best engineering and software people on the planet. They'll collect data and you can bet an update will be released that will solve this. But Apple is always very loathe to discuss issues they're working on, so people just need to show some patience as they won't likely acknowledge this publicly, but they are, I'm sure as I type this, working overtime on understanding why some phones have this issue and how to solve it.

Same issue here... I have absolutely abysmal WiFi speeds (2.2 mbps) in my office on my iPhone Xs Max yet my iPhone 7 is much faster (15 mbps). I'm from Canada, so I paid close to $2k for a phone that's 50% or more slower than a two year old iPhone. Luckily, I have 14 days for a return... which is exactly what I think I'll do. I don't think a software update can fix this hardware issue. This will be the first iPhone that I've ever returned... very upset about this issue.

Same issue here with XS Max. The wifi is incredibly slow compared to any and all other devices i can test on my network, and when compared to my old iPhone X. And for some reason the phone wifi signal plummets if i'm like 15 feet or more away from the router. i never had these issues with my X, which is concerning. I'm on Verizon, and carrier signal has been consistent with my old phone, but the wifi is atrocious.
