Had an unannounced visit from Openreach yesterday and the engineer knew nothing about the RF2 filter so that message hadn't got through from my ISP. He hadn't found anything wrong outside the house and agreed with me that the RF2 was the cause of my problems. He very kindly removed it and reckoned other people in the area hadn't suffered any problems after having theirs removed. I now have the following stats (previous figures in brackets).

The TBB speed test is giving us just under 7Mbps.

Do those stats look OK because at the moment I'm more than happy with my connection speed. We can stream iPlayer in HD which is about as heavy as usage will get in our household. We don't download huge amounts of stuff or have lots of simultaneous users so I'm going to cancel the fibre upgrade completely.
