Sync speed really slow on Lightroom Classic

[transmognify]

I'm trying to sync my Lightroom Classic collections and my sync speed is going from okb/s to 4kb/s.

 I'm uploading 50,000 photos (I made the mistake of rebuilding my smart previews)

speedtest shows that my wifi is getting 50mb/s download and 17mb/upload.

 Does anyone know how I can get sync to upload faster?

I have tried tethering to my phone with 4G and it was about 2 or 3 times faster and seemed more stable, but i can't leave my phone connected for days.

i was thinking maybe an Ethernet adapter connected to my wifi would help. Anyone have experience with these?

 
I'm in Australia using an macbook pro with M1 pro with 16gb of ram and 1 tb of free storage.

 Any advice welcome

I've moved your post from Using the Community to the Lightroom Classic forum.

Does your home LAN consist of only a WiFi Router? No Ethernet ports? No Ethernet switches? Providing connectivity thru WiFi only? And is that a limitation via NBN? That is assuming your access is via NBN. If the NBN provides only a WiFi router (as in no Ethernet) can you change that out to better?

The moreI search the Internet on Home LAN in Australia, and as a result NBN, the more I see that you should be able to have a nice LAN with proper switches. So why in your case WiFi only?

WiFi is a bottleneck, and the more devices connected, the slower, this sort of activity should be via Ethernet, as Ethernet switches handle that better.

I've just bought an Ethernet adapter to connect directly to the router via Ethernet and the speed is exactly the same.

 Any other suggestions?
