Why is my WiFi not working?
Sorry for the ambiguous title, but I have no idea what to do after trying to troubleshoot the problem for some time now with negative results.
First off: The background!
I recently dropped my MBP and dented the lid, which also broke the LCD screen. I took the computer in to a local repair shop to have the LCD replaced. Instead of replacing the LCD they replaced the whole lid to the computer, which I was okay with; but upon getting the computer home I discovered that the wifi was not working and was prompted by the "No Airport Card installed" message when clicking the wifi symbol. This was not an issue before getting any repairs done, as I used the computer after the screen was broken for a few hours and the wifi worked fine. So I took the computer back and they tried to see if perhaps the ribbon wire from the airport card to antenna was loose, or if the card itself was loose. A few days later they called and told me my computer was ready for pickup. When I arrived to pick up the MBP the tech said that the problem was not fixed and that it must be a software issue. He had swapped out all possible parts (antenna, ribbon wire, airport card) with working components from 2 other MBPs and still could not get the thing to work. They had also replaced the lid with my original lid and swapped out the actual LCD screen. So I took the computer home and tried to troubleshoot any software issues.
Here's what has been done so far:
- The Airport card, antenna, and ribbon wire have been swapped out, tested, and found working in 2 separate MBPs. These components have also been swapped from the other MBPs into my computer and nothing seems to work.
- I have reset the PRAM.
- Reset the SMC.
- Ran disk repair on the HD in disk utility. reads as being "ok".
- Deleted and recreated the wifi location in network preferences. When trying to create a new location to "remake" the wifi option, I am unable to select wifi in the "interface" drop-down list, so I had to cancel and press "revert" to bring it back into the left hand list of networks.
- Trashed the system configuration file and rebooted the computer.
- Booted from installation disk and tried to locate network in network utility but nothing for wifi shows up.
- Performed a full system restore from installation disk and time machine backup located on an external HD.
- Updated os X to 10.9.2 from 10.6.8.
Things to know that might help:
- The WiFi was working properly before going into the repair shop.
- Bluetooth works fine still.
- When I am in Network utility in system preferences, I can hit the "Turn Wi-Fi On" button but nothing happens.
- In system information there is no "Interfaces" section or anything else listed afterwards. All it shows is "Software Versions: CoreWLan:..., etc.", but nothing after that list.
After all of my software troubleshooting attempts I took the computer back and the tech at the shop said that all he can think of now is a possible logic board issue.
Please help! This has become increasingly frustrating and I am coming to a loss for ideas on fixing the issue. Not to mention I feel a little cheated by the repair shop because the WiFi was not an issue until after they had "fixed" my LCD screen.
So I can not help but feel like they are responsible for what has happened, even though they claim to have attempted to fix this issue.
Thanks in advance!

Recent update: I have just discovered the Apple Hardware Test, but to no avail because I cannot run it!!!
I've tried to boot it from the install DVD, as well as holding the "option" and "d" keys to boot into an internet recovery mode. Only doing this gains any results, but comes up short anyways. When the internet recovery loads it takes about 30 seconds and then pops up a window that says "Apple Server Diagnostics does not support this machine: Macbook Pro (13-inch, Mid 2010) (MacBookPro7,1/Mac-F222BEC8)."
I also have found out that I need the "Applications Installation Disk" to boot from the optical drive, but my computer came from factory with NO disks! (Thanks a lot APPLE!!) I bought the install disk separately when trying to restore my system before.
I am now running 10.9.2 and have no ability to perform any hardware tests that I know of. Is there any other way to be able to run AHT?
