Since the whole house is not wired with Cat 5 cable I have had to
use Mains over ethernet to provide some networking. However after our
building works the mains in our house is now split in two with two
fuse boxes (containing circuit breakers and RCDs) which then have
separate tails leading to the electricity board fuse.
to say the computer that drives the Sun Rays is on one mains fuse box
and the Sun Ray in the kitchen is on the other.
You can see the effect of the extra hop in the screen shot. Rather
than the maximum 85Mbps when the two mains bricks are on the same
fuse box that reduces to a paltry 13 Mbps thanks to the hop to the
Electricity board fuse and back. This explains why that Sun Ray photo
frame sometimes looses connection with the server when updating the
picture. The other Sun Ray in Sues Office works like a dream.
Clearly using these to form a network between buildings would not
fly. That does however not stop me from being paranoid enough to have
blotted out the ethernet addresses and passwords from the screen
I can see that if in the final network set up I have to have
devices on both fuse boxes I will have to run them as separate
networks which will cost me one extra mains over ethernet brick.
