One day the wifi on my Macbook Pro went out. I was bummed! I tried a few software tricks like re-installing the OS, resetting the SMC and NVRAM, but nothing worked! Still "no hardware installed" for the wifi card. I had to think about how I was going to access the internet on my laptop all the time, it had basically become a glorified desktop. Can I physically connect to the network? Did I bring my ethernet cable? It was a total drag.
Repair was extremely easy! I took apart the computer, carefully followed instructions and replaced the part. I ordered another part just in case that didn't end up being the issue, but it was just a simple cable replacement.
Don't be lazy and put off the repair! Order the part, make it happen, don't live in misery. You use your computer every day, when it's not up to spec you're limiting yourself.
