Very Slow WiFi on new MacBook Pro 13" w/ touchbar

I did have the same issue but this solved my issue.

Quit all of your internet connected applications

Turn off Wifi

Go to: /Library/Preferences/SystemConfiguration/

(Open finder click on Go in meny and then choose Go to folder)

Then delete this files:

com.apple.airport.preferences.plist

com.apple.network.eapolclient.configuration.plist

com.apple.wifi.message-tracer.plist

NetworkInterfaces.plist

preferences.plist

Then reboot you MBP and then reconnect to wifi.

Yes, I'm having the same issue 2017 MBP 15" with touch bar 512 SSD.

My iPhone rocks at 49meg down 5 up and on the 5G network right next to it my MBP rocking 1-2 down and like 0.5 up.

It's so horrible that when I'm working at coffee shops when I use the local network again my phone logs on the local wifi and no issues something always around 10 down and 1-2 up. And again my MBP runs at nearly half that or less. The only way I can get speed out of my MBP with wifi is to use the thunderbolt connection between my phone and the computer and use the hotspot as a wired device. Basically using the phone's antenna and using up data on my phone providers hot spot. But if I don't I can hardly work on such slow wifi network speed.

Also, weird thing is that when I ping the router of whatever network I'm on its ping lag is terrible.

To test this theory I put both my laptop and my iPhone 7 next to each other about 15ft away from the Wireless router.

Both on the same 5G network

As you'll see I have 1193ms times and even 2682ms ping times. I see one test as low as 2ms. But that's a huge variance especially since the majority of the time I'm around 1000ms on my MBP.

So now compare on the EXACT same network my iPhone 7

My average ping was 6ms! 6! my average on my MBP is probably closer to 800-900ms! That's significantly slower on my MBP. And I test this out where ever I go. Hoping it's just my router or something else. But it happens everywhere. I'm starting to think at this point it's hardware related. yes, I did the following instructions on this thread to remove the files as directed. But that maybe worked for an hour and then again this crap.

Anyone else noticing the same?

If the Deleting files part doesn't work. Try this.

This did seem to do the trick for me. The battery on My MBP died last night and lo and behold when I got it powered back up I had blazing fast speed.

SO I saw this and now it's making sense. From another thread.

This did work for me!

iPhone connected to the same Wi-Fi had 10Mb speeds while Macbook Pro 2016 13" with Touch Bar had barely 1Mb speed. Similar slowdown happened in three different Wi-Fis. After removing the configuration files and rebooting MacBook was on par with iPhone speeds immediately.

This worked! OMG, thanks! Saved me $200 if AT&T came out to find out their equipment was operational. I have a new 13" MacBook Pro w/ Touchbar only 2 weeks old that showed same slow 0.24 Mbps to 13 Mbps on worst days. iPhone showed 78Mps, normal speed on same network.

Wow this worked for me too. All night I kept Pinging my Router and seeing that from my brand new 2017 15" Macbook Pro I would get such random ping times out of 4 it would be 1,000ms - 200ms. Then on my iphone 7 right next to it nothing longer than 70ms. So I was so frustrated I was about to take this computer back. Saw this post and thought what the heck I'll give it a try. I'm at a Starbucks and noticing that my Macbook can't seem to get anything faster than 5m down and 1m up. But again my iphone is rocking 50 down and 5 up. SO my witt end said to give this a try and low and behold IT WORKED. I have no idea how those specific files were tracked down to be the issue. But Im curious now. But maybe not so curious as now I can finally enjoy the speed of wifi.

Hello!

I tried the SystemConfiguration steps a couple of times and it finally worked! Thank you!

I had the same problem with my 2017 MacBook Pro 13". I was testing the speeds against my old 2011 MacBook Pro 13", and the speeds were much slower. I tried deleting the files one time, and it didn't work. I was afraid that I was going to have to take the MacBook back after I spent so long getting all of the software I needed loaded on. Just to be safe, I tried it a few more times. After the last time, I loaded up my MacBook, and the speeds were testing faster than the old (although my internet connection is already slow as it is..).

Thanks for the help!

Ha, had the internet providers out to both offices and home with the same wifi issues on newer mac-pro 15 retina. the wifi was great on iphones, ipads, and tablets (cheapies).

I found this post and walked through the steps and went from 13 to 169 with great upspeed.

Thank you @Calby! I also updated the firmware on the time capsules.

What I did was go to Finder, click on Go (in the top menu bar) and then 'Go to Folder' and then paste the address that is mentioned and it takes you directly to those files.

The shortcut is Command + Shift + G.

Good luck!

Thank you for this tip. It worked for my MacBook Pro 🙂

I have a 13inch MacBook Pro touch bar 16 gigs of ram i7

SAME ISSUE. wifi super slow compared to other computers

please help

aa

Thanks! Worked quite well. Speeds went from 8up/2down to 50up/20down.

Just a quick thanks to Calby for posting this tip. The WiFi on my 2016 15" MacBook Pro with Touch Bar was also achingly slow, but clearing these files seems to have fixed the issue for me!

Hi, can't find these files on my Mac, I'm in Mexico and everything is in Spanish but I'm sure that they are not in the Preferences folder.

Where else should I search? Thanks
