Did you mean to say that gkrellm says _89%_ rather than 98%?

In any case, something is funny here with NM since it seems NM should be
reporting the 82/92 value as well.  There are a few updates to the Linux
WEXT spec for signal quality that NM could be updated to follow, though
they weren't that would change the fairly strict interpretation of WEXT
signal quality that NM uses.

Did you mean to say that it only shows _wired_ devices in the menu until
you quit X?  That's probably more a fault of HAL I think.  Next time you
log in, can you execute 'lshal' from a terminal and attach the results
to a reply message to this list?
