Technology Fail

Last few days I've been experiencing sluggish Internet speeds and issues with my router, I get told my existing router maybe dieing so I go out and get a new one.

As I return home with a new router, I turn my computer and old router on one last time to say goodbye and welcome in the new router but what do you know.... Everything's working fine again, it's managed to heal itself overnight, now I'm stuck with a spare! D'oh!
