iPhone XS Max Weak 5GHz WIFI Reception

I’m not doubting your issue. Obviously this thread wouldn’t be here if there weren’t an issue. I was one of the first posters, page 1 or 2. I was one of the first to get a call directly from Apple as a result of my post. But as time went on I realized my iPhone 7 which is still active on another line performs identically to my Max. That in itself is a little disappointing, I would have hoped for measurably better performance in reception for a much newer and more expensive device. My suspicion is that something other than hardware is to blame. Software, maybe, routers, maybe, combination of the two, maybe. Those of us with no significant problems are obviously in some sweet spot as far as contributing factors. I’m just less prone to blame the device since so many aren’t having an issue. I hope there eventually is some resolution that is satisfactory for all because my Max is an incredible device even without having better reception than my 7.

Having the same problem on my XS. I only seem to be able to connect to the 5GHz network when physically in the same room as the router and I get no signal anywhere else in the house. Contacted Apple support online and they apparently think it is a router problem even though I had absolutely no issues on my 3.5 year old iPhone 6.

I do believe it is a hardware issue, so it is quite likely that we won't see a fix. I just wish they would acknowledge that there is an issue.

Software always seemed to be at the root of the problem and it was frustrating to see some insist that it was defective hardware or Intel versus Qualcomm or AMD or the bunny rabbit. However understand that even though 12.1.1 has improved this for you there will be others who may not benefit and others who didn’t have a problem who now do. Fingers crossed that I’m not going to be one of them. After using my iPhone 7 yesterday it was easy to see that my Max is superior in data connection over the cell network even before this latest update. So I’m offering up a prayer that what solved your issue didn’t give me one. But glad to see it worked for you.

If none of the fixes have fixed their issues it's likely because there is some other factor (router problem, interference) at play.

My issue was fixed because it really was purely an iOS 12 bug with no other changes in infrastructure.

I have the same problem with the Xs non-max version. The wifi is half the speed of my iPhone 8 wherever and whatever I do. It also appears to drop and spike a lot more as well.

Same thing here. iPhone Xs. I have 2-3 bars in my bedroom with all other Apple units. iPhone Xs drops connection.

The problem here is simple, Apple is using inferior Intel modems as opposed to Qualcomm

Anyone who is having an issue here has a full year of warranty. If they can't fix this with a software update (which I'm pretty sure they can and will), they'll replace your phone.

I agree cafka.... hold off for now. Most likely software. My x did this identical stuff for 7 months then fixed itself.

Same here. Executive relations sent another new one. Testing it this fr

IPad mini vs xs max 20 meters aways of access point.

72/37 vs 47/24.

This strengthens my assertion that iOS 12 has nothing to do with the issue... it's hardware.

If it's not a hardware problem, then why do my two iPhone Xs Max's behave completely differently, yet all my other iOS 12 devices behave perfectly? This definitely implies hardware.

Hey everyone,

make sure you open up a case with apple. Apple Support is telling me there are no open tickets or known issues with these phones.

Interesting.....6 out 6 people I personally know have much slower wifi speeds and lower LTE signal with their Xs/Xs Max compared to their older iPhones (at the same location during the same time)
