The last 4 or 5 days have seen a return to LAN speed transfers. I have no idea why it appeared or why it went away. There have been lots of WLAN errors as reported by my router. That may not have been the root cause but it certainly wouldn't help. Also, the Intel WiFi modem on one of the clients has been taking firmware, so that may have been a contributing factor. Falls in 'The bug one that got away' category I guess. OK to close.
