AC1200 router - What speed should I be getting copying files from a PC to a laptop ?

Components of the setup -

1) PC with a gigabit LAN port connected to the router through a LAN cable (Cat 5.e)

2) Laptop with an 802.11ac wireless card connected to the router wirelessly

3) Router - Netgear R6220
Have 4 gigabit ports
AC1200 i.e (300+867)mbps
As only one band is used at a time, theoretical max copying speed should be 867/8=108MBps between any 2 PCs

Now I just copied 5GB a file from the PC to the laptop and the copying speed was 52mbps - almost half of the theoretical speed.

This looks bad. Is it bad ? Are the calculations correct ? Am I doing anything wrong ?

Drivers are up to date for all the 3 devices. Everything has been setup properly. The only thing I can improve upon is the cable connecting the PC to the router. I can upgrade to Cat 6. Don't know if it will help much

If I change the setup a little by connecting even the laptop with the LAN cable to the router, and copy some files, I get 90MBps+ speed, which is quite close to the theoretical speed.
I wonder if this is possible for the wireless connection too.

Do let me know what you guys think. I hope this post is clear in expressing my problem and my limited knowledge on the topic. Please do ask if anything is unclear

- ISP is not playing any role here. This doesn't concern internet at all

- Sounds right for which case ?
Case 1 - PC - wire/cable - router - wireless connection - Laptop (Speed - 52MBPS)
Case 2 - PC - wire/cable - router - wire/cable - Laptop (Speed - 90+ MBPS)

- I don't think laptop's hdd is at play here. As seen from the above cases, laptop is able to achieve high speed, but not in case wireless connection. I mean, low speed in wireless relating to HDD's speed ? Highly unlikely IMO

 
Yeah, figured that out and tried to edit it, left that bit in accidentally, fixed now. :)
Is case 2 a case that's already happened?
I think case 1 sounds more realistic.
I'm talking about the read/write speeds of the laptop's HDD, as this is what is at work during the file transfer.
There's a matter of when the data gets to the RAM, and how quickly it is transferred to the HDD.
What is your laptop's model name?
