Chosen Solution
Hi guys, this seems to be a problem for many, but I searched the forums and couldn’t find an answer. Rebuilding a 13” MacBook Pro (A1278) i5. 500 SSD is fine, 4GB of RAM, board is fine. Installed High Sierra, took forever because internet on WiFi was going in and out. I looked around and saw that the hardware was fine, it was connected with IP oddly. But, the icon on the top bar would be checking for signal every 2 seconds or so. I followed some stuff, I found, like creating a new location in net prefs, deleting the connection and adding it back. Removing the library profiles to force a rebuild, reset NVRAM. nothing helped. The hardware is recognized, sees my modem/connection fine. I have narrowed it down to a software issue with High Sierra. Ran diagnostics, said move closer to signal? I’m 10ft. away. I’m hoping for a patch, fresh idea, anything. One method just said turn off the desktop icon and bluetooth, no help. So, I’m stuck and this is always where I come. Thanks. I even tried manual setting up the WiFi using Google’s free dns. 8.8.8.8, 8.8.4.4, no go.
From the sounds of it you have really a simple problem! The antenna leads to the antenna unit held in the black clutch cover have gotten damaged so you are not getting the full signal. You’ll need to remove the display assembly to gain access to the part following this guide: MacBook Pro 13" Unibody Late 2011 Display Replacement then you can slide the clutch cover to the side and then off and here’s the needed part: 13” MacBook Pro Antenna (11/12) recycled The area that is often damaged in at the hinge or the connectors on the AirPort board.
