No, it's not a violation of any protocol, but it *is* needless.  scp  
can pull files from a host just as well as it can push them to it.   
So, it is extra, needles traffic.  It could just be the sheer volume  
of data that has overwhelmed the router.  I have experienced wireless  
routers buckle under the load of very large file transfers.  If the  
volume of (continuous) data is the problem, it could be a firmware  
issue.  You might want to check out dd-wrt or tomato.  I recommend  
this for any user if their hardware is supported and they're not  
afraid to flash Linux onto their wireless router.  I've found it to be  
*way* more stable than the factory firmware shipped with most wireless  
routers these days.  You'll have to check to see if your hardware is  
supported, though.
