Having just re-decorated and re-wired my bedroom, how likely is it that the fact I've re-run the two cat5e network cables (to the same cat5 wall socket), and run them close to a mains feed to wall sockets is causing the link speed to drop to 100mbit? 
It worked at gigabit before I moved it all. Bah.
