Retina macbook pro can't auto connect to wifi after wifi router rebooted

My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted. There is exclamation mark on wifi sign. As I clicked the wifi sign, it shows no Internet connects. However, It is strange there is a tick in front of my wifi name. In order to use wifi, I had to click off wifi, and then click on. The previous version, Macbook pro, has no problem like this. I had deleted all files under wifi library, but still fail. Appreciating for any way to solve it!

Retina Macbook Pro PHY MODE not connecting to 801.11n... slow wi-fi!

I've had the Retina Macbook Pro for about 3 weeks and im really getting tired of the slow wi-fi connection this past week! I tried looking at the advanced wi-fi options (opt+click on the icon) and the PHY MODE always says 801.11g. Heres the catch: I did the same thing on my iMac and it says 802.11n!
I tested this in a few ways:
speedtest on the retina macbook: 2-4 mb/s
speedtest on iMac: 12-15 mb/s
speedtest on iPad: 12-15 mb/s
speedtest on friends PC laptop: 10-15 mb/s
Really crappy speeds on the retina macbook right? I'm about to throw this out the window! Also, I resetted my Netgear WNR2000 router to factory settings 2-3 times just to make sure I'm not overlooking anything on there.
Any way that I can change the PHY MODE to 802.11n on the macbook? or should I bring it into apple and have them check to see if the network adapter is faulty?

I have found a solution!
I took the laptop to apple 'genius' bar and they could not figure out the problem. They told me to download mountain lion to see if it would work. Didnt work! So there was one thing left for me to try: BUY A DUAL CHANNEL ROUTER.
After purchasing that and connecting to the 5ghz channel (make sure you're on WPA2 as well) my speeds are fast like my other devices. I'm assuming the laptop is sensitive to these things! Kinda stupid but oh well; makes sense as the channel is clear from other devices on my network.
So if you're still having these problems try buying a new dual channel router. If it still doesn't work, return the router and have apple repair your laptop (or take it back if you still can).

My Macbook Pro doesnt seem to connect to my Belkin wireless router. It is connected but the internet would not work. any suggestions?

hey guys. I am having trouble with my internet. My MacBook Pro seems to be connected with Belkin wireless router, but the internet would not work. We recently changed the router so its pretty new, and it used to work on my HP laptop. Although there were some problems, it still worked. But now, the internet works and stops suddenly, and then works again.
I would love to hear some suggestions to get rid of this.
Thanks
Kiran

If you have not already done so, read the troubleshooting section in Belkin's user manual, contact their customer tech support by phone or go to its website. Please detail all you have done to resolve your issue. Need this information so that the users can avoid the "been there, done that" scenario type responses. This is to avoid repeating the troubleshooting you may have already tried. Thank you.

Macbook pro can´t find/connect to my hotspot

Dear experts!
I recently moved to a new place and got myself a T-Mobile HomeNet Router. Everything works fine (WiFi and Ethernet) with all devices (iPhone, iPad, iMac, Linux-machine...) EXCEPT my MacBook Pro (specs below in the product section) :-(
Ever since I moved the Macbook can´t find or connect to my home hotspot. Settings on the router are as follows:
- 802.1 b/g (it IS capable of b/g/n but I found a thread somewhere pointing out that this could be an issue)
- channel 13 (deactived auto-channel because my neighbours had overlapping channel settings...this was the only one that worked)
- rate auto
- frequency 2.4 GHz
- 30% signal strength (same reason as above)
- QoS activated
- SSID hidden (tried broadcasting it, made no difference)
- WPA2-PSK
- AES (TKIP and TKIP+AES available as well...but neither made any difference)
I can connect via ethernet, however that´s not the intended purpose of neither my notebook nor the router :-/ Someone suggested it might be an encryption issue but even without ANY encryption the hotspot won´t show up in the list. Password contains special characters but even my old iMac doesn´t seem to have problems with it. I tried connecting manually via "other network" without success. Also via Controlpanel -> Network -> Assist me ...
I´m sitting right next to my router so the signal strength can´t be the cause either (besides all other devices work just fine anywhere in my appartement). Restarted all devices, each one is up to date. Last thing I tried was making the changes in Firefox cause someone suggested it might be a bug in the router software, still no success.....I´m out of ideas.
Posted this in another Mac forum already but no one could help me :-( You guys are my last hope ... does anyone know this issue and how to solve it??
any ideas would be greatly appreciated!
many thanks in advance

nevermind...here´s what solved it for me:

MacBook Pro can't actually connect to Wi-Fi with Self-Assigned IP

Hi there
I have a 15 inch MacBook Pro and it can connect to Wi-Fi but have no actual data coming in. And it says self-assigned IP.
This only happens to my home Wi-Fi, however, I can connect and use Wi-fi at school or anywhere else perfectly. In the mean time, my Android phone and my flatmates' Windows have no problem using the Wi-Fi. The problem has been going on and off for a month, sometimes it works again and sometimes it goes wrong like this again.
During this time I mostly use my other MacBook Pro 13 inch Retina. Until today, this problem happens on my 13 Retina mac for the first time, and the 15 Pro again as well. A few days ago, my 15 Pro started working again, and today they just gone wrong together at the same time.
I just found out that my 15 pro can still work if connected to ethernet, but I can't just work in the living room, where the router is. And as you know Retina doesn't support Ethernet.
I've check on the Internet and found many people have the same problem as I do. I also tried lots of ways to fix it with the information I found online. And nothing works. I even suspect that it's actually my flatmate blocks me out with some setting on the router (Is it possible?)
Anyways, can someone please help me fix it thoroughly... Please and thanks.

Each country regulates wireless networking differently. Wi-Fi devices are restricted to certain frequencies and power levels. The client devices try to find out where they are and configure themselves accordingly. Since a wireless access point (WAP) usually does not move across national boundaries, the Wi-Fi regulatory domain (country code) is set by querying the first one to respond when the client initializes itself. You don't have any direct control over it on the client. If your device is picking up the wrong country code, and is therefore locked out of using some Wi-Fi channels or operating at full power, the only lasting solution is to fix or remove the misconfigured WAP.
To find out which WAP's are broadcasting a wrong country code, do as follows.
Triple-click anywhere in the line below on this page to select it:
/S*/*/P*/*/*/*/*/airport -s | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign ($) to appear.
A TextEdit window will open with the output of the command. The first line should look like this:
SSID BSSID RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
Each line below that one represents a WAP within range. Compare the two-letter code in the column headed "CC" with the ISO code for your country. The code "X0" means that the country couldn't be determined. If a WAP with a wrong code is not under your control, try restarting the computer as close as possible to your own router.

Macbook pro fails to auto connect Internet after rebooting wifi router

My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted.
There is exclamation mark on wifi sign. As the picture shows, when I clicked the wifi sign, it shows no Internet connection. However, It is strange there is a tick in front of my wifi name. Moreover, in preference set, it shows a confused self-assigned IP address 169.254…(showed in picture). In order to use wifi, I had to turn wifi off, and then turn it on. And the correct IP address for my mac should be 192… (showed in picture).
I had tried to delete my preferred networks and tested macbook in my friend’s home, but it still failed. This bug happens in my friend’s macbook pro with retina (same to mine) and macbook air. However, the previous version, Macbook pro (not retina), has no this problem.
This happened just when I reboot the router. It is normal working (connect automatically) when I come back home. Appreciating for any way to solve it!

I have no clue of what an Airport antenna is either. I know my Airport Extreme does not have one.
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Macbook Pro can no longer connect to any wirless connection

My macbook pro has never had any problem connecting to a wireless connection up until recently. For the last two months, I have not been able to connect to any wireless signal although I can when connected directly to the router with a lan cable. these are all networks that I have used in the past, with all correct passwords or even to networks that are not password locked. do you have any ideas on what i can do about this before making the trip to the apple store?

i forgot to mention, its not even a matter of getting connected to the wireless signal with a few bars showing and not function, it just does not connect at all anymore and i get an error message saying:
"there was an error joining the network [the name of the network i am trying to connect to]"

Macbook Pro no longer auto-connects to preferred network

The title says it.
While my computer connects automatically to some (maybe all but one) of my preferred networks, it now does not connect, annoyingly, to the one I use the most often (let's call it NET).
I've triple checked that it's preferred and should connect automatically, and the computer remembers the password, so that if I manually select NET, it connects no problem. But:
a) It won't auto-connect to NET, and
b) If I turn my computer on, when it presents the list of networks to me, I have to wait for it to reload the list, cause if I click on NET originally, it doesn't connect, and I have to refresh the list and try again.
c) Figured that might mean that it's just taking longer to load the networks and is showing me a list before it's actually picked up on the networks, but waiting forever doesn't make it autoconnect; it just refreshes the list.
Any ideas? This is a huge pain.

No idea. You could try deleting the file
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
... and restart your Mac.
To find that file quickly, select the above path (triple-click the line), control-click to bring up the contextual menu, and select Services > Reveal. Drag that file to the Desktop, or directly to the Trash.
This will completely erase your AirPort network preferences, requiring that you select your Wi-Fi network and authenticate again.
What OS X version are you using, and are you using an Apple AirPort Base Station, or a third party product?

My macbook pro can't find my external drive after upgrading os

I have a macbook pro from 2009. I recently upgraded to Yosemite and now it won't read my external drive (Toshiba). I am able to find it in disk utility but I am not able to open it. The device works fine in other computers. I have all my pictures there. How can I fix this problem?

Have you tried following through the trouble shooting tips in this knowledge base article on Firewire?

Hi Buterem,
I'm sorry to hear you are having issues with your MacBook Pro since your recent Yosemite update. I also apologize, I'm a bit unclear on the exact nature of the issue you are describing. If you are having intermittent but persistent responsiveness issues with your mouse or trackpad, you may want to try using Activity Monitor to see if these incidents correspond to occupied system resources, especially system memory or CPU. You may find the following article helpful:
How to use Activity Monitor - Apple Support
If the entire system hangs or locks up (for example, if the system clock freezes and stops counting up), you may also be experiencing some variety of Kernel Panic. If that is the case, you may also find this article useful:

My 15inch retina MacBook Pro ran out of battery and even after charging it. It can't seem to turn on. Anyone knows a quick way to fix this?

I was working on my MacBook when it suddenly shut down. I realised that I forgot to charge it. However after charging it for a few minutes of charging and several attempts at holding the power button down. It doesn't seem to turn on.

Keep it charging for several hours.

My MacBook Pro doesn't automatically connect to my home wifi. Is there a way to set that up?

I'm new to macs as of last night. Which would explain why perhaps this is an easy task, but I have difficulty with it. Here's my situation; my wireless network is password protected. When I initially connected to it it prompted me to put in a password, I did, and then I was connected. Every time I turn my computer back on or wake it up, I have to go up, click on wifi, click on "Tardis1" and click connect. It doesn't ask me to put in the password again, however it doesn't connect automatically like it should. It also gives me this message every time I manually link it, "Mac connected as wep but not wepa/wepa2 personal" or something along those lines. Any help would be great, thanks!

Hello, andyBall_uk. I figured out the problem, and I'm going to reply to it on here in case anybody else has the same issue they can see this solution. I already had an iOS device before, which saved a "keychain" of the old login info for the router. This was back when the router did have WEP security. Since then, it has been reconfigured for WPA2 however my old keychain was trying to join it as WEP.
To solve this, I went to System Preferences>Network>Advanced
From here, I noticed the
[ + ] [ - ] Drag Networks into the order you prefer
Highlighting my router and hitting the [ - ] sign removed the keychain that would previously only connect as WEP. This now allowed my computer to automatically connect to the router every time I opened it or turned it on.

Will Apple take the responsibility? My retina macbook pro (late 2013) seems to be damaged after I received it from the Service Center.

Two months ago, I had some problems with the hinges of the display screen I used to make weird sounds and I was finding it very hard to open and close the display. The Service Center guys said there was a problem with the hinges so, they replaced it. But after I received my macbook back, I noticed that one of the screws was not properly fitted but, I thought that it was not such a big deal and I would take it to the Service Center sometime later to get the screw fitted properly as was not a hinderance with my daily work. When I took my Macbook finally to the service center after 3 weeks, they tried to fix it and there were some problems. According to them the screw was somehow jammed in its place but they at the end fixed it. But, after I reached home, I noticed they applied too much pressure and the bottom of my laptop was bent from one edge and also the screw was in place but the the chassis was still loose and was coming out.
Need Help. What can I do.

Take it back and ask them. No one here can speak for Apple. This is a user forum.

MACBOOK PRO CAN FAIL TO RESTART ITS VIDEO AFTER BEING CLOSED, LOGGED OFF

Most of the time, if I log off and close the lid, things are fine when I open it again. But, from time to time, I'll have to restart to get the display back. As for more information: I recently got a secondary display (not because of this) and now, when this occurs, the secondary display will come up as the primary display, so it's clear that the system really can't find the primary one. The fact that I have to restart the system in order to get the display back hasn't changed (though, in this configuration, I don't have to use the button to it).
Is this something that others see, or is it my own special problem?

Your own special problem. Why log off?
