Retina MacBook Pro Wifi Issues

Hey guys, I just got my rMBP today and the wifi is terrible on it. I have the 2.6, 16gb, 256gb ssd model with mountain lion. For some odd reason, when I'm at home my wifi connection constantly drops. I'm using a cisco WAP4410N AP, if that helps at all. I called apple but they weren't of much help. I also tested wifi at a relative's house, and, for some reason, it worked perfectly for the hour and half I used it. At home, even when I restart my modem, router, and ap, I can only get a max of 15 minutes before the connection drops. WiFi works perfectly on every single other device I have (Android phone, iPhones, tablet, other laptops), and I've tried switching wireless channels and broadcast type settings to no avail. I've deleted all the AirPort preference files (as the apple rep asked me to) and booted in recovery mode, and nothing occurred. I think of myself as being tech savvy, and I am confused as **** right now.
Any ideas?
Thanks,
Krad

Well, give this a shot:
1) Go to: http://www.cisco.com/cisco/software/release.html?mdfid=282414137&softwareid=2824 63166&release=2.0.5.3&relind=AVAILABLE&rellifecycle=&reltype=latest&i=rm
2) Download the 2.0.5.3 firmware
3) Open your access point's configuration page. I'm not sure what your gateway is, since I had to modify mine to match my network. The default should be 192.168.1.245, with the username as admin and password as admin. If you haven't changed any of the default settings, you'll have to connect through ethernet, as the AP doesn't allow you to configure over WiFi out of the box.
4) Click the administration tab, and you should see firmware upgrade under that.
5) Upload the new firmware file, and click upgrade. It takes a few minutes so just wait for the AP to restart on its own.
Hope this helps!

  • Macbook Pro Wifi Issue

    I incorrectly posted this in the wrong thread this morning.
    I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
    I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
    I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
    My wife has a nine year old ibook and has no issues connecting through wifi.
    When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
    I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
    Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
    I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
    Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
    I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
    During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

    Hi nashie1002,
    If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

  • Using third party headset with Retina Macbook Pro (microphone issue)

    Good day, everyone!
    I have very strange issue with my Retina Macbook Pro (Late 2013) OS X 10.9.3
    When I plug in my Steel Series Headset, its microphone not recognised by system and only "Internal microphone" available in Settings - Sound - Input.
    Headset itself works perfectly fine, because when I plug it to my iPhone, its microphone works without any problems.
    Macbook's headphone port also works fine — when I plug in my iPhone original headset to Macbook, its mic works good and I can see "External microphone" in Settings - Sound - Input.
    So headset is ok and headphone port is ok. What is the problem?
    How to force macbook to use headset microphone instead of built-in one?
    Thanks in advance

    Either contact the sales staff at the store where you ordered your Mac from or contact the speaker manufacturer & ask them.

  • Retina Macbook Pro wifi too slow at home, other devices are fine though

    I bought Retina macbook Pro 15inch couple months ago.
    The internet speed seems ok at school, but when at home it is too slow that I can't do anything at all.
    But my other devices like iphone/ ipad works great and has fast internet.
    So I upgraded internet service, from 15mb speed to 30,
    but it still is slow.
    I turned off the bluetooth, and seemed like it help tiny bit with the speed but I can't have anything done with this speed.
    Do I need to buy a new modem / router?
    Thank you for the hlep in advance.

    Hold down the Option key and click on the WiFi Icon on the menuBar.
    This will reveal all sorts of information about your Network and what is around you.
    Look for what channel your Router is on. See if any other Routers are trying to use the same channel.
    Look for the transmit level, something like -75.
    Look for the transmit rate.

  • Retina MacBook Pro Heat Issues ?

    Hello,
    i have noticed that my new MacBook Pro with Retina Display gets exceptionally hot, especially when playing some fairly basic games like "Tomb Raider Underworld". I have noticed the heat in the area of the Keyboard an the bottom. The aluminum between the keys gets so hot that i can barely touch it.
    Has anybody got the same issue ?
    What should i do ?

    see Vastly Improved Thermals from AnaandTech as part of their review of the Retina MacBook Pro.   If you check the bottom of the page you can see if you GPU stress test the laptop it can get sufficiently hot.   About the middle of this page, you can see how Apple redeigned the heat pipes along with fans to bleed off Heat.

  • Installed Windows 8.1 on Retina Macbook Pro - Many issues

    I just recently downloaded the Windows 8.1 .iso file from Microsoft's website. My school got it for me and other members of my club for free so I don't have any install disks or anything like that. I used the Bootcamp Assistant to burn the .iso file to an external hard drive, let it install, and started it up. I'm running it on a mid-2012 15" retina Macbook Pro. Here are some problems I'm encountering. If anyone could help solve any of them, It'd be greatly appreciated.
    First off, when I set the resolution to 2880x1800, most windows and icons are sized normally. However, the taskbar is absolutely tiny and some text (like the desktop icon text) is also very small. Any other resolution makes everything look distorted and blurry.
    I can't connect to the internet. It doesn't detect any wireless networks at all even though I know there are many in the area.
    The sound only works through headphones. Not through the speakers.
    Some text is crisp and clear (like menu titles) but other times it's very pixelated.
    Thanks for any help!

  • Late 2013 15" Retina Macbook Pro - wifi connection timeout with one router

    Hi,
    I've recently purchased a new Macbook Pro retina 15 inch late 2013 model. Everything is fine at home, but at work I cannot connect to one wireless router (Netgear WAG102). The computer tries to connect but I get a connection timeout error after a few seconds for every attempt.
    I have tried every suggestion for wifi issues that I can find on the forums, and have reset the router.
    A colleague has also recently purchased the same computer except 13 inch model - he has exactly the same problem.
    Any suggestions? I suspect given that two of us have the same problem that there is an incompatibility with the MBP and this particular router. I notice that there are quite a few discussions about similar issues with the macbook pro.

    I too have a MBP Retina, 15", late 2013, and am having wifi connection issues.  I've tried several fixes suggested on these discussions and by Apple.  Nothing corrects the problem.  I've been told it's my router, but I find that difficult to believe give that my wife has a MBP 13" 2012 (non retina), that has no issues at all, nor do our iPhones.  It's just my MBP Retina. 
    My issue seems to be when waking from sleep, I lose the wifi connection.  I have to turn wifi of then on again, and it reconnects.  The only thing that corrects the problem for me is when I disable bluetooth.  I have the magic mouse and it's basically useless becuase I need bluetooth on for it to work.
    I find this to be an annoying problem.  This is my first MacBook, and I really like it, but this wifi thing is bad.  Never had this problem with my Windows machines. 

  • 2012 Retina Macbook Pro WiFi problem

    I have a 2012 Macbook Pro with Retina display that's been upgraded to Mountain Lion.  It is having WiFi connection issues.
    Specifically,
    1.  Upon startup it will not find the network.  I have to turn off the wifi and turn it back on to have it find the network.  Annoying.  It used to happen only intermittently; now it happens every start up.  It's getting worse.
    2.  It will randomly every few hours drop the wifi connection, requiring me to turn off the wifi and turn it back on.
    I've tried the one fix people on here suggested: deleting the wifi network profile I use and putting it back in.
    Didn't make a difference.
    Has anyone found a better fix?
    I'm disappointed that Apple released this version of OS with such a glaring problem.  A laptop without a reliable wifi connection is a complete waste of money.

    Happening to me too. Macbook Pro Retina Display with Mountain Lion. I'm experience occassional drops while actively working on my Macbook that requires me to turn off Wireless and turn it back on to get a connection. I've noticed this twice in two days.
    I'm had my Macbook for about a week and immediately installed Mountain Lion, so I don't have a previous version to compare with. I could turn off Bluetooth at the moment, because I'm not using any Bluetooth devices, but it is likely I will be getting a bluetooth device in the future, then this workaround won't be useful.
    I hope Apple can come up with a software patch?

  • Retina MacBook Pro fan issue

    I've noticed when playing games or doing anything graphic intensive, only 1 fan goes on? as far as I know the RMBP 13 inch has a left and right fan but I only ever hear the right fan. I downloaded "macs fan control" and only my right fan shows up there. Is this an issue that needs resolved?

    Thankyou! I had asked an apple "expert" and they told me the device was defected. Obviously they need to some more research on their own products. again thanks
    In your case, this is the definitive place to find out about your specific MBP and all of its internal components.

  • Retina Macbook Pro temperature issue

    Just got my first ever macbook pro (retina model) and although I am loving it until now, apparently sometimes it gets too hot to keep working on the lap under normal use. Normal operating temperatures range b/w 35-45C for CPU heatsink and 45-55C for GPU according to iStat Pro. The temperatures jump to 60-70C forthe GPU and 55-60C for the CPU heatsink while watching videos on youtube. Is that normal? Does this has to do something with flash videos?

    This is quite normal.  Your MBP can get up to a temperature of up to 80˚Celcius before damage can occur.  Your MBP will automatically shut down when it reaches 100˚Celcius.  Do not put your MBP on your lap it can cause burns even at the temperature you stated.  
    You can open up activity monitor and check which programs are eating the most of your CPU and quit them if necessary. 

  • New retina MacBook Pro - WiFi connectivity problems

    Dear all,
    I've recently purchased the new Haswell 13" retina MBP, and I'm having exactly the same WiFi connectivity problems the 2013 Airs had. I have a solid connection for a short time, and at irregular intervals it just drops out. All of my other devices are still connected and have no problems. I've tried with two different routers/modems, but the problem persists.
    Is this a known problem - with hopefully a software fix in the forseeable future, or do I need to return the MacBook?
    Many thanks in advance for your help,
    Nic

    I haven't got a Retina, but I do have the same wifi problem. And if you've looked at these forums, you'll see it's been going on for years and no one seems to have a handle on what the issue is. All I can say is if I were in your place I'd take it back and exchange it. You have the chance now, so take it.

  • 15 inch retina macbook pro graphical issue

    I noticed yesterday that i started getting a pixelated "flicked" across my screen. typically it's the lower half and it tends to go across the screen in a rectangular bar shape mainly. . it does happen when im not using video, but it does appear more often when im using a video. it's very very worrysome to me, but happens so fast it's really hard to describe. I'm most afraid that it could be a hardware glitch, since it started yesterday out of the blue. is there any other people reporting this problem? if so is it covered under warruenty?

    no it appears for a very short time and goes away without any particular ryme or reason. it does NOT show up near the eages or when im scrolling (safari in particular can look glitchy when scrolling). it appears right across my screen from one side to the other. it appears so fast that the pixels might have color, but i can't tell because then it's gone. as i said its shape tends to be a rectantgular pattern going across the entire screen, and i have not noticed it before. quiet odd to say the least.

  • Macbook Pro Wifi Issues with WPA2 Enterprise key

    I have a MBP 13" mid 2009 model. There is usually no problems connecting to home networks. It remembers the passwords and connected seamlessly. However, I have problems connecting to networks with WPA2 Enterprise settings. I had tried it in NYU and I am trying it at my current school too. It keeps forgetting the WPA2 key from time to time and although I have tried all ways to get it to remember the key it still fails. I have used other MBP from the same time frame and they seem to be working perfectly. Even my iPod touch works perfectly with these WPA2 enterprise networks. Can anyone suggest a workaround?

    The networks do support WPA2. It works perfectly on windows 7 and other MBPs. There it doesn't keep asking the password and stores the password in keychain. But on my MBP it keeps asking me for the password from time to time

  • Retina Macbook Pro 13" on Windows 8 Wifi Stops Receiving Data

    Hello!
    I am running a Retina Macbook Pro 13" with Windows 8 Bootcamp. Recently I have discovered that my laptop internet stops working. When I boot it up in windows I will be able to use the internet for an average of around 30 seconds before it stops loading pages but it is still connected to the network. The only way I can actually use the internet is if I keep reconnnecting to my WiFi network every minute or so.
    Can anyone help me with this issue?

    I'm having a similar issue on my brand new MacBook Pro Retina 15". Internet seems to run fine on my windows side, but when I bootcamp into Windows 7, using my ethernet adapter, downloads seem to only get between 80mb-200mb done before it just stops, and I have to restart. I can browse the internet completely fine (and quickly) but downloading large files seems to cause an issue.
    I had to download a Broadcom NetXtreme Gigabit Ethernet driver to get the adapter to work, and I'm wondering if perhaps I have the wrong driver? It's weird that it works though....I also downloaded 7.5GB of Team Fortress 2 seemingly fine the first night, but I think thats because Steam is able to force a reconnect even if it stops working.
    Anyway, any help would be appreciated.

  • New Retina MacBook Pro does not find WiFi after booting

    My Retina MacBook Pro keeps looking for WiFis after it has booted, but does not find any.
    I have to explicitly turn WiFi off and on again after booting to get it working.
    When I put the MacBook to sleep and wake it, the problem does not occur.
    Any hints what could be the problem?

    Not sure if this will help, but you can go into System Preferences > Network and, if you haven't already, create a new location (mine is called "home"), then from this location remove all connection methods from the left column except Wi-Fi. Also, click on "Advanced" and remove anything from the Preferred Networks list that you aren't using. Then click on "OK" and "Apply".
