      No, changing the MTU will have no material impact on any line errors. That's entirely down to line noise. If you're on Base and are getting high errors then either your line is very long or your wiring is terrible.

      The Sky network is, AFAIK, set up for a MTU of 1500. Reducing it will lower your throughput.
