I've had similar problems to spudje. It's been very frustrating having constant network timeouts
I am forced to download things on another computer, copy to USB, and manually install.
Also, I just did a fresh os4.1FE install in WinUAE, updated to update 1 (no issues), rebooted, updated to update 2 (no issues during update), rebooted, and now it's in a constant reboot loop, I can't get into workbench at all. Has anyone else seen this?
