After memory upgrade, wifi and bluetooth non existent

Evening

I have a mid 2012 Macbook Pro, purchased in Jan 2013. This afternoon I upgraded the exsisting 4gb ram to 16gb ram, following the instructions provided via apple.

Upon turning the computer back on after installing, I received the "no hardware installed" for the wifi as well as no bluetooth. After resetting the PRAM, ect, it did not fix the issue.

I ended up backing up my mac to my portable drive and reset the laptop. Upon re installing Mac OSX, there is no longer a link in my settings to the bluetooth or the wifi, as if it was never on the machine in the first place.

settings>network only shows ethernet and firewire, and you do not have the option to add wifi or bluetooth.

I have not found anyone else with this issue searching the internet or this community.

Before I bring the laptop to the genious bar tomorrow, is there a fix so I don't have to waste my time? I must use the laptop for school and I will be without it for a full day tomorrow and I am somewhat screwed as of now. Everything else on the laptop works.

Any help would be appreciated!

During disassembly you have probably disconnected the cable running to the Wi-Fi and BT modules. Disassemble and see if you can locate it and reconnect it.

You can disconnect a wifi / bluetooth cable that quickly just by taking the bottom cover off the macbook pro?

If the cable is in fact disconnected, would that be the reason I can not add these in settings at all?

What speed/brand RAM did you install in your Macbook Pro?

Please don't tell me you installed a non Apple Certifed/Tested RAM to save money.

Install the old RAM back - do a SMC RESET and a PRAM/NVRAM reset and see if everything goes back to normal

Bimmer,

I purchased the folliwing:

Qty: 1 CT3373650

Part Number: CT2K8G3S160BM

Price: $119.69

Description: 16GB kit (8GBx2), 204-pin SODIMM Upgrade for a Apple MacBook Pro (13-inch and 15-inch, Mid 2012) System

Line total: $119.69

My brother purchased the same, and his install was with no issues.

I installed the original memory, did a PRAM reset so far, and nothing has changed. The wifi and bluetooth icons are no wherre to be found.

There are no cables detached when the bottom is taken off.

I guess we will be using that Mac 1 year warranty.

also, when I do go to the apple store tomorrow, I will be bringing the 16gb crucial memory with me. will they charge me to install the memory? Could the memory be faulty? would they be able to diagnose this issue so I would know whether or not to return the memory?

-thanks

before you take it to apple - make sure you install the original RAM.

if you don't, Apple will tell you that the RAM you installed is the problem.

from the part number you gave me - you installed the right RAM made by Crucial for your Macbook.

now, it could also be a bad RAM module. take one out and turn your macbook back on- if problem continues - take the other one out and install the other and turn your macbook back on.

i do however, suggest you install your original RAM and see if problem goes away.

And no, it's not easy to disconnect your wifi/bluetooth cable - it's possible if you were haste in taking the bottom case off but it's unlikely.

good luck with that and hopefully you get it sorted out.
