I'm currently having issues with data corruption when transferring files from my QNAP NAS over the wifi network to my PC.

The files I'm transferring typically are rar files and after the transfer is complete I try to extract the archive and I get a corrupt volume error.

I've only ever had success being hardwired directly to my NAS completely bypassing the TP link router however when I hard wire my NAS and my PC to the router I seem to have some better success however I'm still concerned why I'm getting data corruption over wifi.  My brother has the exact same NAS and Deco system and he seems to get corruption over both wifi and hardwired regardless.

Originally I was thinking it was my NAS however I'm more leaning towards the issue being the Deco routers.

I'd appreciate some insite on this.  

Thank you
