MacBook A1502 - wifi stopped working after battery change

We changed battery for a customer, and it was successfull. Now customer came back 14 days later, and wifi not working.


It wasnt listing any wifi networks, i also checked the network menu, and tried to add a new one, but only stuff like PPoE/Bluetooth etc was there, there was no WIFI to be added.


Tried SMC + PRAM reset.


Also tried on another SSD with a new OS. On this, there isnt any wifi symbol in the top right, and under network - no wifi either.


Whats going on, what did we break during that battery installation :( ?

Check the WiFi antenna’s connector. You may have accidentally forgotten to reconnect it, or it may have gotten broken accidentally.

Wifi cables was attached correctly, allready checked. But thanks for the suggestion.


I think, if the cables for the antenna was broken, it would still show the wifi card in general, which isnt happening :/

I also tried another wifi card + the board that the wifi is attached to. Those 2 things didnt work either.


Does someone have any ideas ? :/
