Link status - periodic downs & ups

[lejeczek <peljasz yahoo co uk>]

hi guys,

Might not be strictly NM related what I'll ask about but 
here is probably best place to start, so if any of you read 
this - I have a USB Network adapter which goes down for a 
ten or so seconds and then up and! it does it every two hours.
