Fixed slow WIFI issue with new Macbook Pro

I just bought a new Macbook Pro

As I started playing with it, I noticed that all my software updates and downloads were taking a long time to finish.  I am paying for a 12 mbps high-speed internet connection with AT&T Uverse, but a speed test (www.speedtest.net) proved that I was only getting up to 4 mbps.

I did the same test on my iPhone and it yielded 10 mbps.

I did the same test on my PC and it yielded the max speed, 12 mbps.

Long story short, I fixed it by changing the Wifi Channel from 1 to 6.

If you are experiencing the same issue, you have to log into your router and change it as well.

First, you need to find the IP of your router.  Open Network Preferences

Click Advanced and click on the TCP/IP tab

Keep Note of the Router IP.  In my case, it is

The next step will vary from router to router.

You will have to log into your router and change the Wifi settings.

Open up a browser and enter in http://<IP of your router>.  In my case, I would enter

In most cases you will have to log in with a username and password.  You should know this, but in case you don’t, try admin/admin, or just admin with no password.  If you are an AT&T customer, the password should be the same as the network code on the label.


Scroll down and find the Wireless link.  If you don’t see this, look for an option to configure your wireless settings.

Once you are there, change the wireless channel from ‘Auto’ to something else.  I selected 6 and it worked for me.


Good luck!

    I have a 2015 MacBook Pro 15″ retina. Same problem. Starts out fast then slows to a crawl. Can i just revert back to the “out of the box network setting” I think i screwed something up in the network settings because i went through about 3 routers thinking they were defective when indeed the service guy found a bad wire on the 10th floor. Now i have a TP link AC router. It works great for about 15 minutes, then down to about 1 mbps.
    I am really pissed at this MBP and i shouldn’t be.
    I could kick myself for returning the ASUS AC router. It was really a nice one.

    I Don’t believe how many fckn hours i have spent on finding the issue… I never would tought that this is the issue.

    In my case the Channel was on 1, so I just set that to 6 and woala, back to 50 MB from 2,5MB :)

    Thanks Again!

    I’m not sure why this worked, but it seems to have been a beautiful fix! It’s been over 24 hours since I changed the router setting from auto –> 6 and the issue has not returned.

    Thank you!
