Well my download speed has gone up slightly but my upload has dropped to only 4.7Mbps and as I'm on an ECI cabinet who knows when G.INP will be reinstated although that won't help upload anyway.
The low FTTC A for my upload is 7.5Mbps although I was getting around 6.7 to 7.1Mbps on the SBG3300-N.
I've tried three Openreach Filters (Mk1, 2 & 3) the MK2 gives best results for me, the MK3 gives even lower upload speeds. I've also tried directly into the test socket using an Openreach supplied filter and also with an ADSL Nation filter and it's still giving similar results.
