This is about what I'd expect for a first backup, "Fouster". Backing up is not just a simple "streaming" operation. The disk image you're writing to is growing, and you're copying hundreds of thousands of tiny files and their metadata. This does a decent amount of random access over the network, which can slow things down.

As you can see from the speed difference between wired and wireless, it is, indeed, the network that's causing things to run slowly. (Otherwise, it wouldn't have sped up when you went wired!)

Once the first backup is complete and you switch to Smart Update, it's going to be significantly faster.

(Note, too -- if your PC's partition is formatted as FAT32 things will fail: the destination you're storing the image on must support files > 4GB, so it would have to be NTFS.)

Hope that helps.
