My 64-bit Vista Home Premium notebook can't back up wirelessly anymore. At around 80%, an IRQ-related stop error is thrown. No new hardware has been added recently, and the only driver update I've made is for the Nvidia GPU.
Backing up with a wired connection works just fine.
I have not run chkdsk b/c this doesn't look like a problem with the hard drive, since wired works and wireless does not. Do you have any suggestions?
