slow internet on macbook air

Try doing this,

1. Quit all apps or programs that are using internet.

2. Turn off the macs wifi connection

3. in the finder window enter this: /Library/Preferences/SystemConfiguration/

4.Find the following 4 files

(1. com.apple.airport.preferences.plist

(2. com.apple.network.eapolclient.configuration.plist

(3. NetworkInterfaces.plist

(4. preferences.plist

5. (Optional) Copy these files onto a thumb drive or another folder on your Mac as a back up in case something goes wrong, then paste them back into the system config

6. After backing up the files delete the files located in the mentioned area above in step 4.

7. Restart your mac

8. Also try restarting your Wifi router just for good measure before restarting your mac.

9. Once restarted this should rewrite the files on your system config, and fix your wifi problem.

If this doesn't work please respond with anything else happening to it so i can try and further help you.

You are very welcome man I am so happy I solved your problem. I might even be a little to happy due to the fact that this is a school project for my tech class and this got me a lot of extra points. I am so glad that I helped fix your problem and in the future I hope that any other problems you might have (Hopefully not) I can help you out with. You have a great rest of your day, or evening when ever your read this and God Bless

If you have not done this already, try it..

Power off the router. Unplug it from the wall. Wait a while.

Plug it back to the wall. Power the router on. Wait until all lights are lit properly. It will take a while.

Restart the computer.

Start up in Safe Mode.

I think I'm having the same problem but I'm not perfectly clear on your instructions...

I find the 4 files, copy and paste them to a thumb drive or some other folder. But after that step I'm not clear on what I do?... Just copy the files that I just copied/pasted to another location and paste them back in the original folder? Delete the files in the original location and then copy and paste the files I've already moved to another location back to their original place?

Hey there,

Wanting to try your 'fix' for what I believe to be the same problem however I have version 10.12.6 and the folders are not the same. I see someone else has the same issue. Please return with the names for this updated version. I feel like I am living in the dinosaur age of dial up!

This worked on my MacBook air A1237 BUT after I load a page or 2 it goes back to being slow as before? I can delete the files again and reboot and it loads an internet page super fast but only for a minute or so?

Hi there,

I'm having this problem with my MacBook Air too over here in the UK too. When I tried to follow your advice I found that the second file listed com.apple.network.eapolclient.configuration.plist wasn't there. The other files are accounts exitsts, boot, smb-server and wii message tracer, should I delete one of these instead do you know? I would be extremely grateful if you could let me know as my slow connection is driving me nuts, I can't even do any updates its so slow it gets kicked out all the time. Fingers crossed.

Kind regards,

Susie Jazz

The line:

com.apple.network.eapolclient.configuration.plist

May not be a necessary file in your particular instance. An internet search indicates that some versions of the OS don’t use or need it. My MacBook Air running the latest software works with or without it. After the initial fix provided above, mine never restored that particular file, and works fine, with much faster wifi.

Hope this helps!

This solution worked like a charm when nothing else has made a difference. Thanks for posting it!

Im running 10.12.6 and the folders and files you specify do not seem to exist anymore
