Keep in mind that a RAW is about 50MB and the JPG-L is around 15MB so downloading files will be slow over Wi-Fi. 5G Wi-Fi gives you more speed but shorter distances. I'll use a USB-C to USB-A cable and connect to my PC to download files and that's still not the fastest when you're downloading hundreds of images. If you pull the cards out and use an adapter, it is a little faster, at least with my setup.
There is a price to pay for resolution and disk space consumption. I store my images on a Network Attached Storage (NAS) with RAID 1 to ensure safety and that slows the process down another notch even when you have a gigabit network.
As a suggestion: If you haven't done it, check to be sure you are using the best channel for your Wi-Fi connections. Often Wi-Fi routers will use the same channel which means that your neighbors are on on the same channel with you, causing interference and slowdown. There are free Android phone apps which allow you to measure the signal strength and channel usage to help determine if you need to move to a better channel. Google for help and there are tons of articles.
