Another wireless MBL Time Machine issue

This has been running about 8 hours already. This is using ethernet with wi-fi disabled, because it began to stall and never complete a backup on wi-fi after making the first back up on ethernet. Wi-fi worked, albeit slowly for a few weeks.

I had just reset the the MBL by deleting the sparse bundle backup, shutting down the MBL, letting it sit or +15 minutes with power disconnected, removing and re-adding the MBL to Time Machine, then starting a new backup. So we’re talking 32 hours to back up 199.88 GB? That seems a wee bit slow to me. I’m really beginning to question why I bought this device. A USB backup took about an hour. I use Mountain Lion 10.8.2. on a Macbook 6.1. Any ideas about what else I might want to try?
