BTW check carried out at the same time gives 36.37mb/s D/L and 12.88mb/s U/L with 25ms latency. Ookla shows 37.82mb/s D/L with 14.99mb/s UL and 17ms latency on a very local server.Pinging BBC returns 15ms and PLusnet 28ms. These have all been very typical reading on my 40mb/s Plusnet fibre service for ages, testing via ethernet as usual and running under Win8.1.
ThinkBroadband says the new anomaly may be due to RWIN, which means nothing to me even when reading through the voluminous notes obviously intended for techies.
I am not aware of any other changes apart from the fact that routing has morphed from 87.***.***.*** to 91.***.***.*** for no apparent reason.
Could someone kindly interpret this weirdie and tell me what to do about it please?
BTW, have now run ThinkBroadband three times after allowing time and rebooting. Similar oddity each time.
