MacBook Pro 16 2019 10.15.4 WiFi Issues / Dropping Connection -- Help!

I confirm, the same issue fixed in the described way (reinstall MacOS)

Same issue, we bought 4 of the new 16" last December and all of them are experiencing this. BT KB and Mouse and AirPods also suffer brief disconnects when the wifi is dropping.

Now using LAN from USB HUB to avoid this annoying problem and not using BT KB or Mouse

I hope Apple get this resolved.

DPJ,

One of my colleague had a case open with Apple support. Had to send his laptop in to get hardware replaced.... Same issue when the device returned.

As a test I used my 2015 MacBook Pro for a few days w/o any issues. I was on wifi, using AirPods, Apple Keyboard/Mouse and corporate wifi. During that test, the 2019 MBP's experienced several connectivity blips (separate events). Meanwhile, I was solid, with 0 issues for 72 hours. When I returned to my 2019 MBP, issues returned.

We have a new case open, and Apple has collected logs from my 2015 MacBook and 3 of the 2019 16"MBPs.

Finally, we are all senior IT consultants, and I'm confident in our ability to troubleshoot and identify any environmental variables that could impact our Wifi performance/reliability.

Based on the data we have provided to Apple, something is up with the gear.

Thanks

I had the same issue and tried the same thing (disabling the Apple watch unlock), it worked fine for a good 2-3 months but then started happening again. Upon turning the "Unlock via watch" feature back on, the issue stopped happening!?

We have two other MacBooks (2013 & 2015) at home, a couple of iPhones, all connected to the same Time Capsule router, none of them exposing this problem. They never have either.

I do not really think that the watch itself is the issue but more the radio in the MacBook itself (which somehow gets "reset" every time you toggle this "watch"-setting). It could be a starting point for Apple to "backtrace" to the root-cause (I am over-simplifying things of course, it is never that easy).

Hi

I found this thread as I'm having the same issues, mine slows down and then eventually gives up until I toggle the wifi setting off and on again or wait 5 minutes. I've disabled the Apple Watch and so far not seen any slowdown, still pulling 400-500 MBs but I'll leave it toggled off for a few days to se if that fixes it. I have a case open with Apple and wiped and reinstalled Catalina last night so still setting stuff back up again but the issue was happening today. I have wifi monitoring on and have captured dumps when this happens but nobody in Apple is interested in seeing these.

If this fixes it, I'll still progress the case with Apple as it's important they are aware the watch causes issues. If it doesn't fix it, then I'll return the laptop to Costco for a refund.

I can reproduce this 100% as you can see in the attached video. This is on a partition Apple Support asked me to build and it has only Catalina and Ookla Speedtest. After an unlock with watch, Speedtest crawls at first and never fully hits the 516 targeted download speed.

I've since upgraded to Bug Sur on that partition and early indications are that it's doing the same.

I plugged in with a third party dongle that uses two of the USB-C ports and had Ethernet as one of the ports. Using this, I get 550MBs regardless of whether unlock with watch is on or off, it makes no difference.

Apple have requested I take the MacBook Pro in to a store to check the Airport card but that's going to be a week at least before I can get a slot.

I was getting nowhere with wifi on Big Sur, even the public beta. I've also failed to get the disc to partition for Windows. I tried a full restore from backup after wiping and when it finally restored, it said there was another 11.1 update. I've installed that and it's brilliant - full speed back on wifi and unlock with fingerprint is coming up all the time rather than at random.

Still can't partition the drive, but 2/3 of the most irritating issues fixed isn't bad.

Before you become irate about this, see my summary posted nearby:

I haven't had a drop out with my 16" MBP since changing to a new router to the Netgear X6 R8000 Nighthawk and im using the Apple Watch unlock :)

So after multiple conversations with Apple support, they told me to send in the unit. I'm waiting for the Apple stores to reopen to get them to work on the laptop. I hope to have an update in the next few weeks. I will update this thread.

Thanks

Hi, It seems that Apple is aware of the problem. They did release a new update 10.15.6 supplement update for September but it also seems that they pulled it for whatever reason.

You are adding a "me, too" to a thread that is already 9 pages long.

To get the best advice, start a new discussion, and post your Option-Wi-Fi snapshot as well as your Mac model and macOS version.

How much weaker?

Post the numbers.

Hi,

I have the same problem with my MBP 16 of 2019. The wifi is slower than my MBP of 2017. The wifi speed of the MBP 2019 is always half of the MBP 2017. I can see in the parameters that the detection is weaker. They are placed in the same place. I tried a new installation, but the problem is still there. Is it a hardware defect?
