I've just purchased a VR2800 having upgraded from my ISP supplied router. The connection is generally stable however when syncing large files to Egnyte the connection is dropping out. It eventually restores but in the meantime my mac is locked up. There seems to be a clear link between a large file uploading (100+mb) and the connection dropping.

I've now had to revert back to my original hardware as the issue is too disruptive. Can anyone suggest how I might fix this before I return as faulty?
