I've got a usb to rj45 console cable.
But the document says this:
Will it still work?

Yes, if it is RS-232
-
RS-232 is the signaling. RJ45 is the port type. If the RJ45 end goes in the AP and the USB end goes in the computer and it is RS-232 compatible (console isn't a type, it's just a description) then you are all fine. It's not will it "still" work, there is no "despite" as long as everything is RS-232.

My laptop does not have a serial port. So do I need some type of adapter for it to work?

It does have one, USB is a serial port. (That's what the S stands for.) RS-232 is a signaling standard, it doesn't denote the adapter. That's a common myth (that the A+ liked to repeat a lot.). USB and RJ45 are the standard connectors for RS-232 for the last many years.
-
Any USB console cable has to have an adapter in it as the other end is not USB. So it's actually USB to "something". You just have to make sure that that is RS-232. It should say on the cable.

Here is the console cable I got

Sigh!!!!
I hope you seriously don't think this answers his question - He's assuming a 9 pin serial port...
Yes you need a USB console cable, not a 9 pin to RJ45 cable - or you need a convertor - 9 pin to USB.
*Edit - I do see you sorta kinda addressed the USB in the second post.. but still.

@Fredtx said in Cisco Access Point Install Help (AIR-AP18321-B-K9):
Yep, that should do you just fine.
Now the question is - what are you going to use to terminal connect to the com port? Windows used to have a TTY session on it - back when modems were common, but I think that was dropped ages ago.
You can you PUTTY, that's probably the easiest way to go.
If you want to hassle with WSL, you can follow these instructions to get a terminal that will connect to the com port.

No, nine pin doesn't mean RS-232. Can be, often is, but RS-232 like I said is what matters. Just because something uses a DB-9 (which is NOT the standard for RS-232, DB-25 is) doesn't mean that it's RS-232. That's why what I said was stated very specifically, it has to be RS-232.

Hence specifically why I pointed out that assuming RS232 meant a specific port was a myth. I addressed exactly that!

I realize you addressed that, but you didn't get him to the answer he needed, not in that one post, the followup post was closer.

But I did. I said IF the cable was RS232 that it would work. I was super clear on BOTH answering his question AND correcting the thing you assumed he was assuming. I covered it all.

Here is where I was extra clear, after having already said it but not as clearly.

Thanks everyone. I was able to console into the device with the console cable I bought from Microcenter. I did have to install some drivers since Windows was not recognizing the device. After that, it recognized it as Com3. One of my coworkers was able to remote in my laptop and help me configure the AP.
Appreciate everyone's help. I may be posting more often, because I'm getting exposed to a lot of technology I'm not familiar with. LOL
