Wifi still hangs - wireless TM backup related?

[bozz2006]

After upgrading to 10.7.1 I have had wifi hang on wake-up happen twice. I've noticed that both times it's happened while TM is in the middle of a backup, presumably when I shut the lid. When I open the lid and my wifi is hanging, I can see that TM is in the middle of a backup. After a couple minutes it returns to normal and at the same time TM stops the backup. Anyone else?

Yep. They made this perfect in Snow Leopard. It's a shame this took a huge step backwards in Lion.
