Thanks for the guide Asam!
Yes, I would like to know as well the exact model number for iMac 21.5 4K 2017? The other iMac guides sugged another module that may not be compatible with this model? The only bits that are readable are BCM?
Oh, I saw it - step 29, I must be blind ;) It’s BCM943602CDP, thanks!
I may have damaged the sockets for the antenna connectors (#1 and #3 reading from L -R) in the process of reassembling my late 2017 iMac after replacing my 8 GB RAM DIMMs (REMBER testing after a kernel panic failed, and OWC sent me new DIMMs, which pass REMBER testing.
However, now I cannot pair my BT mouse, or unlock the iMac with my Apple Watch, or pair my AirPods Pro reliably. Curiously, my Magic keyboard works just fine. When the AirPods Pro seem to pair, the music playback to them is awful (stuttering). I know that I couldn’t pop those two antenna connectors onto the little pins on the BT/Airport board the way they were before, but I don’t seem to have any network issues (SPEEDTEST results are similar to previous testing). I don’t know where to get an Airport/BT card or whether that really is my issue, but it certainly corresponds to making the repair. I did reset NVRAM and delete the BT p-list files; neither of those seemed to make any difference.
