MBP WiFi Problem?

Hi everyone I recently bought a used MBP 2011.
Recently when I turn on the mac, the wifi will connect though it will have an explanation mark and will say: No Internet Connection. I then have to fiddle around, log off, restart my computer etc until it finally works properly. The problem isn't from the router, other laptops/PC's in the house work fine. Ethernet works fine so I know the problem is from my Mac. My OS X is up to date with everything. I'm running 10.9.4. Works fine at cousins house, work, school.

1.Power Cycle
   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 the lights are lit properly.
   It will take a while.
Restart the computer.
Start up in Safe Mode.

2. Turn off Extensions, if any.

10.7.3 MBP Wifi Problem - Endless Timeouts & Dropped connections

I've been reading around here a bit already and so I know many other people are having Wifi issues with Lion, but given that there are so many discussions and so many pages of talk, it's hard to go through it all, and using the search I haven't found anything that's quite similar to what I'm experiencing, so I'm starting a new topic...
Basically, I've got a late 2006 MacBook Pro, installed 10.7.1 (form 10.6.8) on in back in Aug 2011 and everything seemed to be fine. I updated to 10.7.2 sometime in Jan and still didn't notice any issues, but wasn't using Wifi at all at the time.
Then in Feb I moved and started using wifi (with a Cisco N router), and noticed that often, the system would not automatically reconnect to the network after waking up from sleep. Just selecting the network manually worked on the first try every time though, so it wasn't so bad.
At the end of April, I finally got around to installing the 10.7.3 update. I read it was supposed to fix wifi issues and so was looking forward to it. It installed fine and didn't seem to cause any problems...
2 days later I moved again (to India), and all **** broke loose... Now, I can rarely connect to wifi (a Beetel G router, configed with WPA). Around 25% of the time, the network won't show up in the list (despite being a clear 5ft from the base station), and when it does show up, 95% of the time I get a "connection timeout" error - often immeadiately, but sometimes it takes about 10sec to respond. On the same network, 2 Win 7 Dells and an iPad 1 all work flawlessly - it's not the router...
One the occasions that I am able to connect, it usually works fine, but if I put the computer to sleep and wake up again, there's no guarentee that the connection will work again - it's back to the lottery. And sometimes even when it's connected, the wifi stays (according to the menu indicator) but the internet connection disappears (to the point I can't even ping the router - 100% packet loss, let alone any internet server)
I've tried zapping everything I can think of (PRAM, SMC), repairing permissions, clearing the remembered networks from the System Prefs, deleting old Locations and creating new ones etc. I have a clean install of 10.7.1 that I booted off of, but it still had the same issues!
Here's the Wifi output from System Profiler (trying to use "Home Network"):

I'm pretty savy with computers and have dealt with all kinds of stuff before, but this one is beyond me, and is really annoying! I konw my machine is old, but it was totally useable up until these Wifi issues, and now wifi is basically useless.
From what I've read, it seems like its a driver issue with the Atheros card in my machine, but most people seem to be complaining about dropped connections (mine rarely drops) rather than timeout connection issues. I've also never had the "hardware not found" issue that many people have, so I think this is something different.
Anyone out there have any advice? I'm getting close to losing it with wifi since the update!

Sorry - to add:
I don't think it's a question of WPA vs. WPA2, or even channel number - I have 2 identical routers here and neither work (both default to WPA Ch 11) but I changed one to WPA2, new SSID, various channels and still had the same problems.
Another thing to note that should be irrelevant, but who knows: the Firewire controller on my machine died back in Fall 2010 - to the point where the system won't start-up unless I remove the IOFirewire***.kext from /System/Library/Extensions , and as soon as I do that, it works flawlessly (minus Firewire). It meant I had a **** of a time installing Lion becuase I can't boot off the Recovery Partition (which has the drivers baked into it), but by cloneing my HD, installing Lion onto the clone via a borrowed machine, removing the .kext's and cloning back, I got it on and everything seems to be fine otherwise... I posted about that problem before, but never got any answers. And it wasn't just me, my father has a late 2007 MBP and the same firewire issue happened to his within 5 days of mine (not a power spike - I think it was shortly after some system update if I remember correctly).

So what about now ? C2D mbp wifi problems

So now a lot of people had posted their wifi connection problem with the brand new C2D mbp, and many of you had called apple support and still have not solved the problem.
Now C2D MB is out, what should we do ? is there any official reply from Apple regarding this issue ? or should us just go out to buy a brand new wifi router just for this laptop ?
Interestingly, there are 5 unprotected wifi router in my neighborhood, I tried them one by one, the only one that I could successfully connect was made by D-Link, and the pre-N card in C2D MBP was made by the same company too, does this imply something ?
Truely, I just wanna know Apple is working on this and there will be a solution/update/fix/patch in the not-so-far future.

There is lots of speculation to the reason for the poor wifi signals and connectivity and no true answers.
Many attribute it to routers, hardware, software, or encryption.
Regardless, for CD or C2D it has become a nuisance and I trust that apple is/has been working on it.
You need to take your problem on an individual basis though. I would suggest calling applecare or bringing your computer to an apple store. If calling applecare try to confess that you tried all the "stupid" things that solve wireless problems... like turning on your wireless!

Here I write a little desperate with this problem that I have on the MacBook Pro (late 2011) with WIFI .
For several months ago, when I power on the MBP is all apparently normal , spend a few minutes and I lose the WIFI , the icon still comes out as "connected " but no WIRELESS signal , I turned off the WIFI, but, when I try to change back to turn ON, the icon of WIFI still OFF ( the inverted triangle ) . Restarting the MBP and still the problem no signal and appears as disabled , delete PRAM several times until finally everything works again , spend some time and again the same thing sometimes is fine for several hours, go out to eat and return and again the same thing, the worst was when I saw the message "Hardware not found" and "X " where the icon goes WIFI . I rebooted several times and not managed , this was the "hardware not found" message. Some time ago I went something like , when Lion had and read that resetting the PRAM and managed , never came out , but now even that it manages , and it is becoming more common , I thought it was the OS ( MacOSX Mavericks ) so I reinstalled (I'm not used Time Machine, I install all again ), this work the lasted several days without fail, until she passed again, I'm out of WiFi, when I see no WIFI signal in the list , restart me WIFI goes off and I can not change , restart it goes back to " hardware not found" and so on.
Now desperate for this, I opened the MBP , disconnected the cables from the Airport card and reconnected with care and making sure you are all well , turned on the MBP again and works!!, I lasted two weeks , then I thought it was that. But again the whole problem again.
Already investigating more online and I found some details from other users
1 / Both WIFI and Bluetooth are on the same card ( the q disconnected and reconnected )
2 / If the card was wrong , losing the WIFI Bluetooth should lose , but I tried Bluetooth and has no problems
3 / Reported that resetting PRAM or SMC but still, in my case, does not work.
Now all I have left to rule is the WIFI antenna that is located ( if I remember correctly ) for the bottom of the screen, and according to several users this tends to fail from constant use to close or open the MBP (or either to cover or uncover ) , and sometimes it just heats and heats close to this area .
Has anyone had a similar problem? My MBP turns 2 only on March 7, 2014 , I can not believe all that cost me and now is about to fail , I have a Sony VAIO Core 2 Duo for about 5 years (or more) ago and is still running and has been dropped many times and nothing has ever happened : (
Additional data on my MBP ,
Several months ago ( long before the problem with the WIFI) I changed the hard drive for an SSD ( 250GB Corsair Neutron X ) .
There is a problem that often makes me too, is that when you close the MBP ( to open ) , and open it back again ( out of sleep) the following happens :
1 / It instantly freezes when waking from sleep and I have a long wait to enter the password.
2 / When you leave idle normal let me put the password, but just when giving ENTER freezes
3 / Out of sleep, let me put the key, ENTER and when I load the desktop freezes
Another problem :
This only happened to me a few times , as I mentioned , my MBP is formatted ( have Mavericks ) before formatted (clean install without time machine) , I closed the MBP ( I sent to sleep) and the open the screen was black , but as with bright, and not leave the state, turned off force ( pressing the button) , start the MBP again (power on) charged normal gray screen with apple but with a fairly low brightness, spent a few seconds and turned the brightness to normal and started normally .
I hope some can help me with these problems.
PD : I'm from Peru , if anyone knows a trusted service that please let me know .
Thank you very much .

Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

Is there a fix for the WIFI problem with Lion? How can I get Lion off of my Mac?

What model of Mac? I have a MBP running 10.7.3 and do not have that issue. From the other couple of posts I've seen about it, it seems to be maybe an issue with some iMacs? Have your tried searching the Lion or iMac forums for similar issues, just to see if anyone has hit on why it is happening?

After installing Mountain Lion, WiFi problems

I installed Mountain Lion on my mac mini and have been having intermittent WiFi problems ever since. It seems to be getting worse, connection is now being dropped several times an hour as opposed to several times a day. I have tried all the suggestions that have been put forth with no luck. My iPhone can use the WiFi with no problems. What I have found that seems to work everytime is to go into the Network system preferences, turn WiFi off, and then immediately turn it back on. I am using the most recent Apple Airport Extreme. I urge Apple to fix this bug quickly.

Don't know what to tell you, but I also have an AEBS-Gen5 with a MBP Retina and Mac Mini using WiFi. Both are running Mountain Lion and I don't have any WiFi connection issues. Two iPhones in the household use WiFi with no issues along with a printer and 2 Windows 7 laptops.
First thing I would try is to shutdown all computers connected to the AEBS. Then power off the AEBS and finally the cable/DSL modem. Then reverse the order and power on the cable modem, wait for all the lights to be solid, power on the AEBS, wait for the light to show solid green; then power up a computer that uses WiFi.
If the above doesn't work, you might try repairing permissions via Disk Utility. If that doesn't help maybe a PRAM reset would work.

Sluggish MBP - wifi probs

Hi there.
I recently upgraded from a MB to a MBP - brought a refurbished one from the Apple store.
Anyway, since i've had it (and compared to my older MB) its performance is not up to par.
I used migration assistant to transfer everything over from the MB to teh Pro. Tht was fine, but now i'm getting problems usch as:
- random crashing, just be surfing the net and it comes up "please restart your computer"
- program crashes - firefox, parallels - this NEVER happened on my MB
- crashing when waking up from having the laptop in Sleep - have to restart (every time)
- crashing when coming out of screen saver (only occasionally)
-wifi problems - probably the biggest problem, i have the Pro in the same spot as where i had my Macbook - and it only gets like 3-4 bars, sometimes less (strength) whereas my macbook was always full
- also - sometimes it says its fully connected, and router is fine etc, but theres no connection - can't surf the net nothing, and i can turn my macbook on and use that fine at the same time the pro isn't!!
these are the biggest problems, also a heap of minor ones.
So yea, i've only had it like 5 days, and haven't had a problem free day. I'm seriously thinking i might downgrade back to the macbook.
I got it refurbished, so it has a one year warranty.
Any ideas as to whats causing this, what i could do about it?
its all updated and stuff also.

Hey, cheers for the tips.
I thought the same, and i found myself going to back to my old MB to do tasks that required better performance!
Anyway, i done the disk repair, i think its helped, but still not o good still crashes when coming out of sleep mode. And randomly crashes while on the net etc (tho not as much).
Also, i just brought Spore, and this crashes like mad - sometimes right at the menu, other times i play for an hr then randomly freezes..
wifi is better (tried some tips on tht page) but still not as consistent as my MB.
So i'm ot really happy with it, should i just take it back - will i get a refund or a exchange? is that procedure pretty straight forward (or am i in for weeks of waiting and being mucked around...)

Strange wifi problem on a brand-new MacBook Pro

Hey there, I'm new here. Desperation has got the better of me, and I hope I can get some advice.
So, last sunday I bought a brand new 13" MacBookPro with 2.8g i7 processor and 10.7.2 OS (I can't update to 10.7.4 because System Update tells me the download has been tampered with or corrupted after I waited 2 hours for it to finish, but I'm trying a direct download from the website). Here's the exact product: http://www.amazon.com/Apple-MacBook-MD314LL-13-3-Inch-VERSION/dp/B005CWIZ4O/ref= sr_1_5?ie=UTF8&qid=1340301247&sr=8-5&keywords=macbook+pro+13
Everything is all perfect except for a strange wifi problem. Note that the wifi does not turn-on or off, it doesn't disconnect after 'sleep', it doesn't get less speed, it doesn't constantly leave a preferred connection (once I chose my home wifi it always connects to it no problem). The wifi bar is always full. What is wrong is that the internet is kinda 'glitchy'. The best metaphor I can think of is that it's like a car that has to be pushed down the road before the engine can start. Please, bear with me because this is kinda hard to explain and I'm not good at tech lingos.
One of the symptoms is browsing can get really slow and inconsistent, almost as if the wifi gets turned off in the middle of browsing. For example: if I look something up on Google and then open 5 new tabs, probably only 2 or 3 of those tabs will eventually load while the other two will not get past the long 'http:.......google.....etc etc' address and will eventually show one of those 'error loading page because there's no Internet connection' notice. This happens a lot. Sometimes I have to refresh/retry loading a page a couple of times before it finally loads, then usually everything will get back to normal and I will be able to open multiple tabs with no problem, but in a couple of minutes I would try to open another site and the problem will start again.
So I tried to see how it does with downloading using iGetter. Fortunately I also have a Macbook (white-plastic casing one) and my brother has an old 2006 MacbookPro so I can compare. With those two older Apples iGetter starts receiving data in less than 8 seconds after I click Start, while my brand-new Macbook Pro can take up to 15-20 seconds, sometimes it doesn't even start at all and I have to re-click the start button. But once the download actually starts (on my new MacBook Pro), it downloads like normal, it doesn't stop and the speed is also as good as I can get. Strange huh? Hence, like a car that has to be pushed before the engine starts.
I also tried 'speed testing' from a website with all 3 laptops. On my old MacBook and my brother's MacBook pro, once I click 'begin test' it takes only a couple of seconds of 'ping' before the download/upload speed measurements start, but with my new MacBook Pro (just like with iGetter) it takes up to almost a minute before the measurements start, sometimes it won't start at all and I have to re-start the test.
Well, thanks for reading. And hope you can help me shed some light into this. Because it is really preventing me from really enjoying my new MacBook Pro. And if this is most likely a hardware problem, I'd better get back to the store and try to get it replace or something while it's only been 5 days. *cheers*

Hey guys.. Thanks for the replies. Unfortunately, I bought the MacBook in Indonesia where there are no such thing as an AppleCare. The only option is to leave the Apple product to one of the 'Authorized Apple care centre' and have whoever do whatever to it without guarantee of success. As for returning it and getting a brand new one, I also don't know if there is such a deal here, but that's actually a good idea, will try to go to the store tomorrow. Although, I'm worried that the problem might be with OSX Lion or something and getting a new one won't help.
mark75090, I've tried resetting the router when I first noticed te problem, didn't work though. I've checked my new MacBook's wi-fi (option+click wifi bar) and it says 'PHY Mode: 802.11g', so does my MacBook and the old MacBook Pro. I don't know what those mean though, and I don't know whether or not my router is an N., can you tell me more please.. I have tried with the other two turned off, and only the new MacBook using the wi-fi but the problem persists. I have also tried connecting directly to the router, but as I described, the problem is too subtle for me to notice the difference.
Also, if I create a brand new Wi-Fi connection in network preferences and connect to my router through the new Wi-Fi profile, the problem seems to be gone for an hour or so, then it always comes back though. I have also just finally installed 10.7.4, but it doesn't help either.

Wifi problems still exists?

I sold my gs60 that had an 870m back in january mainly because i couldnt bare the wifi problem. I really loved the laptop and everything about it but everytime my laptop overheated the wifi would drop from 100mb to 1mb or less at times, monday im thinking of buying a new msi laptop and im wondering if these models that are currently being sold on amazon and etc still have the wifi problem or has it been fixed?
And trust me, i read the forums, i read the guides and im pretty decent with computers/software and etc, i uninstalled, reinstalled, updated it, changes adv. settings and even though it improves certain things the problem was still there. So does it still exist?
Or should i just buy a USB wifi?

This problem only occurs in earlier patches of Intel WiFi card of GS60 2Px (8xx series of NVIDIA graphic cards) and not every unit was affected.
If you don't want to take this risk, I'll suggest you buy GS60 2Qx (9xx series of NVIDIA graphic cards).
USB WiFi is a good idea. It certainly has a better signal comparing to the WiFi embedded in the body of the laptop.

How come they still haven't fixed the ios 6 wifi problem on ios 6.0.1 making me mad -.-

I know apple or the tech support doesn't read this but come on tell them to fix the wifi problem that started from ios 6 and still continuing to ios 6.0.1. I already gave them another feedback like 5 days ago. I really don't want to reconnect to my wifi everytime. I already did everything possibly to fix my wifi problem. I know its IOS 6.0.1 because it started with ios 6 and still not fixed by apple update to 6.0.1.
I have a very limit data plan of 300 MB on at&t and I don't want to go over so I rely on my wifi most of the time.

Maybe you just lucked out but both my devices running ios 6.0.1 have wifi problems shutting of at random times during sleep. I know you guys will say when its plugged in it doesn't lose wifi true but I never remember having this problem in the previous ios verison from ios 4 to 5(On my Iphone 4, and from my Iphone 4s from IOS 5) until I updated both devices to ios 6 or even when I had a iTouch 3rd gen long time ago I never remember it shutting of my wifi. I am telling you this never happened before IOS 6 where I need to leave it plugged in just to have my wifi during wake up.

I thought I believed my iPhone 4 with iOS5.0 would not disconnect during sleep mode. However, I was wrong. What I did was to ping the IP addresses on my iPhone 4 (iOS5) and iPhone 5 (iOS 6 then, and iOS6.0.1 now) when they were in sleep mode. Very true that there were timed-out on both devices. Once I woke them up, ping went thru. I did a scan on my home network using my iPad while the other 2 phones were in sleep mode, I was not able to see them.
I thought my iPhone4 did not disconnect too. But again, I think the reconnecting to wifi on iOS 5 is SO MUCH quicker than on iOS6 so user would think there was never a disconnect.

Wifi problem after.4.3 update on xperia z

Hi all,
After updating my Xperia Z (C6603) to build number 10.4.1.B.0.101 I've been having connection issues with every Wi-Fi network.
I've checked the forum but I only found problems about people having Wi-Fi issues with their smartwatch, I do not own a smart watch this is just a general networking issues.
Here's the problem in detail:
When having no Wi-Fi switched on while booting the phone the phone will start without any issues, I will receive my 3G/4G signal and I can browse, e-mail, everything.
Once I switch on Wi-Fi it will start connecting to previously stored Wi-Fi access points but will not connect. Eventually it says that there was a problem with connecting, even though this will take several minutes.
I can go into the Wi-Fi settings, select a different Wi-Fi network (if it is in range) and press connect, however the settings app will freeze at that point and eventually I'll get a notification that the settings app has stopped working.
I have found a "work-around": I switch the Wi-Fi to on, power off the phone and power on again. Now the Wi-Fi connection immediately powers on without an issue once the phone has completely booted, it also will connect to the default Wi-Fi connection that is in range. A different issue appears however once I move out of Wi-Fi range, it will no longer pick up my 3G/4G signal. It is also impossible to switch off Wi-Fi or switch Wi-Fi network connections without rebooting the phone.
As I said before this happened to me after updating to version 10.4.1.B.0.101 after having it received through OTA update. I do not have root access on my phone either so this can't be it.
Is there anyone experiencing the same issues? Is this somehow related to the issues people are experiencing with their smart watch connections (as seen in this topic: http://talk.sonymobile.com/t5/Software-Updates/wifi-problem-after-4-3-update-on-xperia-z/td-p/490591...
If there's anyone who is experiencing the same issues, or has found a fix for this I'd gladly hear from you.
Regards,
Danny

Email and big wifi problems.

Email and big wifi problems.
Why does it take 6 minutes to send a photo attachment when my iphone 4 will do it in 30 to 40 seconds ?
Why will my email account be recognised and log on only half the time?
Why does the wifi keep dropping out?
Why does the speed and signal vary when I'm sitting two feet away from by wifi router?
All settings in my phone have been reset twice as per advice from vodapone

Thanks very much, jjgraphics. I will grit my teeth and try India once more, as you suggest, and then get in touch with the moderators.

If I install Yosemite and find that the wifi problems are too bad, can I go back to Mountain Lion?

Almost everything I do on my MacBookPro requires a steady wifi connection. I have been reading all the horror stories about the wifi problems with Yosemite. I would like to install Yosemite, but would like to be able to go back to Mountain Lion if the problems are as extreme as I have been hearing.
Details: My Mac is 3 years old (Apple Care ran out 2 days ago!). I recently upgraded from 4GB of ram to 16GB.
Router is a Linksys E4200.
I have an Iphone-4s
My husband has an older MacBook running Lion.
I connect to an Epson Artisan 835 with wifi via my router
We have no need to have the Apple devices communicate with each other.
I am currently running an appliance in Virtual Box. One reason I want to move to Yosemite is to be able to run it in VMware Fusion instead.
Thanks.

Hi there CarylLynne,
If you upgrade to Yosemite, you should be able to use the following article to revert to the previously installed OS using Time Machine, named:
OS X Yosemite: Revert to a previous OS X version
Thank you for using Apple Support Communities.
Take care,
Sterling

Wifi problems with new ipad

I'm trying to learn how to correct wifi problems with new iPad. It is the wifi only, 64GB model. I want to be able to use it at work, where we have a great wifi network. I can usually connect to our network with no problem, but after an hour or so my iPad loses the network. When I try to reconnect, I see that the network is showing full strength reception, but I get the error message from the iPad that I am "Unable to join" the network. My iPhone connects to the same network seamlessly, as do all of the other iPhones of my co-workers and the older generation iPads that some of our staff has.
At other locations, I typically have no problems (home, apple store, etc.) but I have had the same situation pop up at a coffee shop where I could see that there was a wifi network available, but I could not join it even though it was the shop's free wifi.
I have tried turning the iPad off, turning off wifi and turning it back on again, and forgetting the wifi network in question. I can't think of any other methods that are available to an end user to correct the problem.
I have already gone to the Apple store to swap out the unit, and the newer one is having the same symptoms.
Can anyone offer any advice here? This is quite frustrating.

No problem! Have a read at this most interesting article which has special significance as regards your models!

Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
