I own 2 macs. One MacBook Pro (Catalina) and one Mac studio (Monterey).
Both are connected to the same network via WiFi, but the mac studio has incredibly low upload speeds, making programs like Dropbox unusable.
After an online speed test, these were the results.
MacBook 100.73 Mbps upload
MacBook Studio 0.64 Mbps upload
I have no firewall activated.
I would be very grateful if anyone can point me to a solution.
iMac 21.5″, macOS 10.14
By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself. The main reason is that they are relentless in scanning your files, non-stop, looking for things virus-like patterns in Everything. When completed, they do it all again.
The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.
You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.
Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.

Are both of these Macs in the same location when you run these speed tests?
For the Mac Studio, how down the option key, and then, click on the Wi-Fi icon on the macOS menu bar.
Note the following values, and post them here:
Does your current network consist of a single Wireless Access Point, or is a Mesh-type wireless network?
hold down the Option key while you click on the Wi-Fi Icon in the menubar. you get a snapshot of current conditions like this older one. Screenshot, photograph or transcribe the values shown and post back here for analysis.

Thanks for the reply.
Since posting this, I have realised the mesh system I use is partly to blame.
But....
I can still connect to my mesh system with my older MacBook pro and the upload speeds are totally fine.
It's a bizarre problem, but can only assume my Mac studio is the only setup that does not like the mesh system at the moment. It has been fine in the past, so I can only assume a firmware update to the mesh system or an update to the macOS has brought this problem about?
Very low upload speeds on one mac.
