In my setup at home, I have my wireless access point sitting next to my
HDHR.  Depending on the channel I've got the AP configured to use and the
position of the antennas, I get a lot of corruption in my HDHR captures. 
I've found that even a slight move of the antenna can cause problems.

In these situations, I get solid signal strength.  The symbol quality (as
reported by the Windows HDHR tool), is low, though.

You might check to see if there are any other devices nearby that might be
causing problems, especially if something has moved recently (even
slightly).
