What is J0, J1, J2, J3 for on this Apple wireless card?

Upon a SSD drive swap I broke one of the cable connectors to this chip and I'm not sure what's broken now. Everything seems to be working. WIFI, Bluetooth and iSight Camera. I have a Macbook Pro 2011 Unibody (A1278). Anybody have some insight on this? Thanks.

Those are antenna connectors. Though I'm not sure how one would break them.

Your wireless interfaces may now suffer from any combination of the following symptoms:

  • Less range
  • Less speed
  • Less stability (against interference)
