iPhone XS Max Xs Max - Subpar Wi-Fi Performance (Solved!!)

Two speed tests - faster one is from the iPhone 7 Plus, and the slower of the two is from the iPhone Xs Max. Internet is running through an enterprise-class firewall and the AP is a Ubiquiti AP-AC-Pro.

Same SSID, about 10 feet from the AP. The 7 Plus was usable from anywhere on my property. The Xs Max is almost unusable if I go to the second floor of my house.

I am not pleased - Is anyone else seeing anything similar? The Max was set up as a new phone (no restore) - and I've tried disconnecting and re-connecting to the SSID, and using different SSIDs. Similar results.

Edit: Solved - Reset network settings. Settings - General - Reset - Reset Network Settings

Tbh I have Similar issues with my x, I don’t think the WiFi performance is very good at all. I’m sure others will say theirs is fine etc . Have you tried resetting network settings or restarting the phone?

My max is getting 40 and my 8 is getting 140. We have 300 but my google Wifi has been a little finicky and I have to kids playing Fortnite right now.

Would the Max speeds be affected by the fact that my phone is still downloading it’s backup from iCloud? Or maybe my Max is on 2.4 and my 8 on 5 even if they are next to each other?

I’ll find my X and test it too...but usually My X and 8 were similar.

Yes I assume if it’s downloading then the speed would be slower

Download speeds are significantly faster on my XS Max. +100mbps on my home internet. (Gigabit) And this is compared against my iPhone X (Qualcomm)

I don't notice any difference. I'll get the 6+ out of the drawer and compare head to head later, but my wifi isn't the bottleneck.

I was having really poor WiFI performance on my XS. Reset network settings and its all back to normal.
I owe you a beer.

Seriously - in all the 10 years or so I've owned the iPhone, I've never had "reset network settings" do anything useful. Today, that all changed.

Sitting in another room about 25 feet from AP and this is more like it:

Nice! I'll keep that in mind when my Max comes because I always seem to have issues with my internet speed on my 6.
Also, you should update your original post for people to quickly finding the solution. :)
