Slow wifi due to missing cable
I had to replace my MacBook Air keyboard because I spilled water on it. During the disassemble I accidentally took the metal top of one of the antenna cable that goes into the Airport/Bluetooth card.
Both wifi and Bluetooth are working, but the connection is very slow compared to when it used to be. Also, the connection is normal when connected to Ethernet cable
Is there a way to repair this metal top?
Thanks in advance
