After resolving some technical issues away from my property BT have restored my connection to 33 mbs. Like most people I have many wifi and ethernet connected gadgets and as I restarted everything I noticed that switching on my windows 10 desktop PC caused the ping to increase ten fold and the speeds (using the BT Wholesale checker) to drop to around 5 mps.
On further probing I could see only one app using the network and that was the Amazon photo storage app. Task manager showed that it was using 5 mps of my network and that it was the only app that was using the network.
Stopping this photo synch app very quicly restored my speed to the 30+ level it normally is. As soon as it restarts the speed took a nose dive.
Has anyone had this or a similar problem? Is there any sort of solution other than to keep stopping the app from running?
