MacBook Pro losing Wi-Fi Connection - antenna connection problem

My wife started complaining two weeks ago about being dropped off the Internet using a Wi-fi connecion.We were just a few months out of the warranty period for the MacBook Pro 13 inch laptop that was purchased in March 2011. I had an old wireless router and went out and purchased a new one from Netgear. I had no problems with my Dell and HP Windows based laptops wi-fi connection anywhere in my house. We still had connectivity problems with the MacBook. I went on to the Mac user support community and found a lot of helpful ideas but none of them worked. I had loaded the Netgear Genie software - it shows when you are connected to your wi-fi router and has a signal bar graph that shows you how strong the wi-fi signal is from the router. I noticed that the only time the signal was strong was when I was in the same room with the router. I began to suspect the antenna or receiver in the internal wi-fi card in the MacBook Pro. I read online that the antenna for the wi-fi modem in the MacBook is in the display part of the laptop, while the wi-fi card is in the base. The antenna was connected through the hinge between the two. I wondered if the connection was being broken when I opened the display to the full viewing position (90 degrees). I tried a little experiment. With the laptop in the opened position and the Netgear Genie sigal bar graph being displayed, I walked down the hall from where the router was to a room where I lost the signal. I had no bars on the graph. I started closing the display on the laptop to about a 45 degree angle. The wi-fi connection came back and I had full bars on the Genie signal meter. I could also get onto the internet. Opening the display a little wider broke the wi-fi connection - and I'm sure also opened up the antenna connection to the wi-fi module. I'm going to contact Apple support to see if there have been any recall issues with this problem - I feel it is design flaw and that many other users are having the same problem - based on the number of postings I have seen with wi-fi connectivity problems. In the meantime, I have ordered a mini wi-fi USB adapter that is Mac compatable to bypass the internal wi-fi device for now.

Thanks for the replies. I went through all the fixes posted on line including the one mentioned above. The problem is a physical connection problem from the internal wi-fi card to the antenna in the display. The fix would be to replace the hinge connector, which would be very expensive and not covered by Apple because I didn't extend the warranty. I ran the problem by Mac support and they concur that the problem is probably the connector and there is no recall on the problem in their system. I opted to go with the wi-fi USB wireless adapter. My wife no longer has to go around with the screen closed at a 45 degree angle to get a good signal.

Hi Stevecapo,


I was very happy to find your post because I too have the same problem with my macbook pro. I tried many things to fix it and nothing worked. Then I found your post and put my laptop in a 45 degree angle and bam! My laptop is connecting to the internet again and it doens't matter where i am! I was wondering if you could tell me the exact usb wireless adapter you bought so I could purchase as well?


Thank you.

Hello Jcandillo,


I'm glad this helped. It took me a while to figure out that the trouble was in the hindge. I bought the Saxony Micro Mini USB wireless b/n/g 802.11 Wifi Lan adapter for $14.99 from Amazon. You have to load their drivers for your MAC. They have them on line. The device is small and I found the signal a little weak at the far side of the house. By adding a foot long USB to USB extender which acted like an antenna, I found it would work everywhere in our house. I folded the extender cable up and used a wire wrap to keep it short. My wife is the main user of the PC and has been very happy with the performance - no more complaints! I also shut down the old internal wi-fi device so there would be no conflicts. Good Luck!

The problem is one of 2 things, on older unibody mac books (2010) the wireless card is in the plactic bit under the screen and the connection to the main board either breaks needing replacement or becomes detached needing plugging in.


On later macbook pros the wireless card in on the mainboard and three antenna leads go above the hinge and into the plastic choke below the screen where the antenna board is located


In the latter case I got a new antenna board and leads and replaced it and it works fine now, The only problem is the Isight camera lead is attached to this as well and unless you want to unglue the screen it is impossible to attach. What I dis is cut off the new camera lead and use the old one as it was still working


I also put the antenna leads in some heat-shrink to hopefully protect them from the bending on top of the hinge

I class this as a design flaw on the part of Apple as it was broken leads waiting to happen
