I have the integrated SkyDrive client installed on my Windows 8 laptop. Every time I connect to wifi, SkyDrive just hangs with a message like "Uploading 8.9KB of 3.4MB, 113 files remaining" (depending, of course, on the actual files waiting to sync) while the system tray icon churns.
I used my laptop disconnected all day and connect to wifi at home at night, when I'd like to sync everything. Right now the only work around is to exit and restart SkyDrive. Once I restart it, everything works fine and SkyDrive will sync as I work as expected.
