MacBook Pro constantly losing wireless connectivity

You should use the cable-modem supplied by your cable operator. There should be no need to second-guess your cable operator when it comes to the cable-TV part of this equation. If you are not getting proper support from them, switch to a different service.

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?

Grant,

I am only passing on what I have been told by high level Apple support. It seems ridiculous to think that only docsis 3.0 should work with Apple products. None of my other devices have this problem. This is what the support representative said, not me. I am not asking here for advice on how to deal with my cable provider, I am asking if anyone else can verify the same problem with a docsis 3.0 modem so that we can rule this "solution" out as a community.

DOCSIS is the cable interface. Nothing to do with the Wireless side of things.

This problem is getting worse and worse on my Macbook Pro bought in 2009.

Dashzap-

You are using 802.11n mode, which takes a big chunk of bandwidth. That leaves it exposed to interference from other devices in the same band.

You are using Channel 2 in the 2.4GHz band. There are only THREE Channels in that band, and it is subject to interference from microwave ovens, baby monitors, other Routers, certain portable phones, and Bluetooth devices.

RSSI (Signal Strenghth) of -64 is probably a bit low, but not dangerously so.

There ia a table in this article with some guidance:

User tip: AirPort - Optimal Base Station Placement by Tesserax

Transmit Rate of 117 is not the highest it could be, which indicate you are seeing some interference and the speed is backing off the fastest possible speed of 150.

--------

So I think you are getting interference in that band, and it is slowing down. That may be contributing to disconnecting as well. But unfortunately, it is not definitive.

from:

http://en.wikipedia.org/wiki/802.11

You would be using that last chart -- a large chunk of the spectrum -- and your neighbors may be contributing to the interference.

I get email messages anytime someone posts on this thread - so I am keenly aware of what has been going on for YEARS (I first posted years ago).

That we have spent so much time STRIVING to figure out Apple's problem - is utterly incomprehensible to me.

What a derelict business - who would sit quietly while THEIR CUSTOMERS STRUGGLE.

Just had to add that today - L

I agree Lauren.

The MacBook Pro is supposed to be a portable device. And as most of us know, our older devices work(ed) just fine with whatever router we were using. Maybe some of us can find workarounds for stationary use in our homes or offices, but good luck in using your MBP internet in hotel, cafe, airport, or university settings. Are we supposed to tell all of those businesses they need to change their systems to suit our precious snowflake MPBs' needs?

Still of the opinion that purchasers of what is supposed to be the world's best laptop should not have to wear tin-foil hats while head is tilted to the north during a solar eclipse to get proper wi-fi connectivity.

Still no issue using Firefox!! When I try to use Safari it's FREEZE CITY!

That is not a WiFi problem. You should post your symptoms on a separate thread with an appropriate Title where Readers can help you.

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??????
