New Macbook Pro M3 slow wifi since setup

Possibly similar symptoms, but NOT the same issue.

For Wi-Fi, each and every case depends on the exact conditions in your "network neighborhood".

Please hold the Option key while you click on the Wi-Fi icon in the menubar, to create a snapshot of operating conditions like the one just above. Transcribe, photograph, or screenshot the results and post back here, or start a new discussion with that information

... and what speed on Internet speed test on the MacBook Pro?

and if you hold down the Option key while you clock on the Wi-Fi icon, what do you get for operating parameters, like this older version provided by MrHoffman:

If you were connecting to the Internet through a High speed CABLE whose specs such as crosstalk and impedance were well controlled, using high quality standard cables such a Category 5 or Category 6, you MIGHT be able to says something about Apple hardware.

You are instead Broadcasting your signal over the air using radio signals, using channels that are open and Shared. EVERYTHING about its performance depends on exactly what else is around you -- your neighbors' Router sgnals WILL have profound impact on your Wi-Fi performance. Setting this up properly so as not to DIRECTLY clash with your neighbors data is essential. "It depends on your 'network neighborhood'".

It also depends on how far away your Router is from the computer, and what construction materials might be attenuating the signals.

Example: My home is solid masonry construction. I have determined experimentally that the attenuation of Wi-Fi signals when passing through a four-foot-think brick chimney makes the resulting signal unusable.

I have the same issue. I have to use my Galaxy Note 20 Ultra as a hotspot to go online period. Everything else in the house works except this 3k piece of junk that I purchased today. it timed out when I was trying to migrate, crashed, and wouldn't connect to a LAN or wifi. On a lark, after 3 hours I used the phone with security off and that worked. This is a disgrace. If I can't get it to connect to my ATT fiber network with 2gib speed, it's going back to apple.

if you would like some technical assistance instead of returning your Mac, please start new discussion and post the exact model-year and model of your Mac, and what version MacOS you are running.

Then hold the Option key and click on the wifi-icon on the menubar, and screenshot, photograph, or transcribe the operating parameters that appear there. Looks like this older one:

Great.

Now please post your option-WiFi snapshot and lets get to work own why that's not working for you.

I'm unclear on the responses in this thread asking people to be more specific. Similar to the poster, I purchased a new M3 MacBook Pro Max and experienced the same problems with wifi. The four iPhones (11,11, 13, 14) and four other Macs in my house (intel, intel, M1, M1) have no issues with wifi dropping and slowness.

If someone asked me if they should buy an M3 pro for 4K USD, I would resoundingly say "No" until they resolve whatever is happening with the sub-par wifi connectivity on the M3 MBP.

Hi there,

I have been having this issue for quite a while now. For me, your workaround seemed to work at first (using either an USB-C hub or an HDMI to USB-C cable) but then the issue re-appeared.

At the moment I am using Powerwire and have the WIFI disabled while I am using my monitoir(s), it's the only thing it works for me.

Best of luck.

<<. it's either the wi-fi hardware or driver issue. >>

Your conclusion is NOT supported by the many posts here on this issue.

When you choose Wi-FI, you are choosing to use Shared radio signals over-the air through a network neighborhood that may contain devices creating interference, or neighbors' routers competing directly with your signals. The radio signal Strength falls off as the cube of the distance to the Router, and building materials (walls, ceilings, windows) cause additional losses. Solid masonry construction like thick brick chimneys, cause very large losses.

By far the majority of the issues are caused by conditions in your 'network neighborhood' and need to be examined on a case-by-case basis.

Actual Wi-Fi Hardware issues are extremely rare, and mostly tend to be caused by disconnected antenna leads after service.

Configuration issues are few. Driver issues encountered to date are essentially none.

--------

One other under-appreciated point: When you change what version of Wi-Fi is in use, such as by upgrading to a Mac with more advanced Wi-Fi capabilities, your data can present a larger over-the-air 'footprint' and subject the same data to more interference from other devices, both Routers and interference generators.

I'm having the same issue. Just bought a new MaBook Pro M3 Max (IOS 14.1.1), and the wifi (both 2,4 and 5 Ghz) does not work (while it works perfectly on my other 2019 MacBook Pro with i9 Intel). I recently had a similar issue with a Mac Mini M2 connected through LAN, could fix it only after switching the TCP/IP settings to manual. But unfortunately I still haven't found any solution for this M3 case. Please Apple do something, it is quite embarrassing to buy such a great machine and then not being able to connect to the Internet

Seems like a few people are having the same issue, or “similar” at least. I have an Intel MacBook Pro, 3 iPads, 2 iPhones, an iMac all within 3 feet of each other, all fine with the internet. My new MacBook Pro 16 M3 Max is the only one with issues.

this discussion is already quite crowded with many different systems, and solving these problems needs intense concentration.

To get the attention YOUR issue deserves, Please start a NEW discussion with a Title that will attract readers who can help you, and post your model-year MacBook Pro and the Option-WiFi snapshot data for that computer.

Same issue here. I have some different devices in my room and M3 PRO is the only device with limited wifi connection.

Even the iPhone 13 Pro Max can reach 800mbps, but my Macbook only gets 150mbps.

Can HDMI cable create interference, even when connected to a different MacBook? It sounds weird and doesn't even make sense.

Devices in the same room without any issues:

iPhone 13 Pro Max, iPhone 14 Pro, Samsung S20 FE, Macbook Pro 16" 2019, Macbook Air M1 and a PS5.

modern Wi-Fi routers use the spectrum from 5,000 to 6,000 MegaHertz and WifI 6e uses additional spectrum to and slightly above 7,000 MHz.

This this could be a sub-harmonic of, and influenced by, the very high data rates used by HDMI 2.0 and above.

This makes it even more important to be using tested CERTIFIED cables for HDMI.
