Q: MacBook Pro constantly losing wireless connectivity

Grant,

I can't even begin to tell you the amount of time I've spent on this issue.  I recently went into an Apple store to inform the Genius and store "leader" that after they replaced my computer I continued to have the issue, however, using Firefox instead of Safari seemed to resolve the issue.

The leader told me I needed to bring my computer in as it was a software issue and they need to reload.....and do this and do that.....

GAAAAA.  Already spent three hours in their store one day on a RARE day off doing all that crap and they gave me a friggin' new computer!!!!

Like I said...GAAAAA!!!  Sorry, Apple.  Still love the MacBook Pro, but using Firefox (which I don't like as much as Safari) solved my issue.  How many more hoops does a person have to go through?

I am reading this thread and there are some people missing root cause here...

When mac goes to sleep and wakes up, sometimes it looses wifi connecting and cannot reconnect.

If you turn off and turn on wifi or delete network and add it again in most cases wifi is established...

Firther investigating this problem I came to conclusion that this is network problem rpobably with DHCP and this command usually solves the problem:

open terminal

sudo su; ipconfig set en1 DHCP;

additionally start stop wifi if it doesn't help...

it doesn't matter wheter you use safari, firefox or wear thin foil hat

Apple please fix this!

If I'm in Safari and my computer goes to sleep, yes, I will lose wifi connectivity.  So far, if I'm in Firefox and my computer goes to sleep, I can sign back on and go right back to whatever I was doing.  Trust me on that.

I tried everything regarding deleting, renaming, and putting networks in a different order.  I had to turn the wifi on and off numerous times throughout a work session.  Losing work I was doing on the internet because my wifi froze was a real joy!  I sit five feet from the router and my husband does not ever have any issues with his 5-year-old PC.

Actually, there are multiple problems in this thread all with one of the same symptoms: Lost WiFi.

I do not lose WiFi when my computer goes to sleep. I lose WiFi randomly while I'm working on the computer and using the Internet. Truthfully, I can be happily browsing or reading email in Firefox or Chrome, and when I click a button or whatever to get to a new page: No WiFi.

For me this started only after I had the logic board replaced. Before that, my Early 2011 MBP running Mavericks worked just fine. I never lost WiFi (though the faulty logic board gave me lots of other problems).

I got one of those USB wireless adaptors that someone mentioned a few pages back, and I have not have any issues. Did that fix it? I don't know. I also tried many of the suggestions in this thread.

Hey Apple!

I am really tired of turning off and on wifi every 2 minutes to enable to surf on internet. Do something already!!! I really don t get how Apple people have been reading this topic and have done nothing. What a nightmare!

PS. I even turned off and on wifi to post this message because i lost the connection.

I have exaclty the same problem.... I have a MACBOOK PRO late 2013 13.3   What apple doing about that??????

Readers here are other Users like you. You are not talking to Apple people when you post on these forums. Apple makes no promise to read these posts, and only responds here when an initial post goes completely un-answered for days.

If you want Apple to hear what you have to say, you need to say it to one of these methods:

• the genius bar,

• telephone support,

• feedback page,

• any National accounts or educational accounts or developer accounts you may have special support for.

Great to know there aren't any Apple people actually looking at the Apple forums. I have a new MBP (Nov '13) and I'm experiencing the same issue as the other 500 people who have posted here since 2008. I would have anticipated a fix by now.

This is my first Apple computer. I've been an iPad user since Gen 1 and I've never had any complaints about iOS. Mac OS is a different animal entirely and I'm seriously considering switching to an Ultrabook with a buggy-but-understandable Windows OS.

Thank you for sharing your frustration with other Apple users.

The other people who have posted here have a wide variety of problems, not one problem.

You have posted only your conclusion that your problem is the same as the myriad of problems other are having. Since you have not posted any of your symptoms, Readers are powerless to help you even if they wanted to.

Theres no word to describe this kind of problem, its a kind of ridiculness.

In less than 5 min of working, internet connects and disconnects randomly and automatically more than 15 times.

I lost all the trustable towards Mac and towards they support, they can't solve my problem

It is so incredible and I dont know how to solve it. In fact it started after actualise to Mavericks, but know i formated the computer installing snow leopard again and it has the same problem.

I returned to Mavericks.

I have another computer at home a Microsoft computer and does not give me any problem, it holds connected for days. Also an android mobile phone and does not give any problem.

My brother has another macbookpro and he also have problems to connect to the wifi.

Apple is going too low and theres no appearent solution for that sofware problem?

Or i missed any answer duing the last 133 pages?

Please post what you get by holding down Option and clicking on the WiFi icon on the MenuBar. It will look similar to this:

What do you get for PHY mode?

Channel?

RSSI?

Transmit Rate?

How many other networks do you see?

To be exacts it looks as this:

https://www.dropbox.com/s/0prljxbnqm91k8w/Screenshot%202014-04-29%2021.34.11.png

You are in 802.11n mode on channel 1 in the 2.4GHz band, the most crowded and most subject to interference.

You have acceptable signal strength at -64, so your antenna is not disconnected.

A transmit rate of 104 out of a possible 150 may indicate you are trying to grab a 40MHz channel out of that band, but are seeing interference and have backed off a little bit from the fastest speed. You appear to have too many neighbors to use a 40MHz Channel in that band.

The problems seem to be related to throughput. When your Mac sees too much interference, it looks for a new Network and tries to join the new Network instead. Make sure no other networks are on the list to be joined automatically.

--------

You could benefit from:

• Resetting your Router, so that it will automatically pick the least-busy Channel

• If you change your Router settings to use only a 20MHz Channel instead of 40, OR change the setting to 802.11g, you would get more reliable operation.

• A dual band Router would get you away from your neighbors interference and be more reliable.

mine looks like this,

I have another network at home both provide me access to the internet what happens with that one:
