Hi! I recently bought an external GPU dock for my laptop and made a mistake. I bought the one with and M Key and it doesn't fit the slot for the wifi or the available slot for an m.2 SSD.

I don't know much about keys and stuff. can you guys help me out if this is the right cable adaptor for the wifi key?

I forgot to take a picture of the available slots, though I could when I get home later if really needed. I think that it's an E Key but don't take my word for it.

my laptop is a 2015 Acer Nitro v17 Black Edition and I have an Asus Expedition 1050 Ti laying around and hoping to play some new-gen titles on it. I just wanna make sure this time around that I don't waste money :) TYIA!!~
