This morning my Download Speed is 28.3 Mbps, its normally 45-46Mbps. The SNR has dropped to as low as 2Db whilst watching it, and is now just below 3. My router shows my connection Current rate at 49Mbps but maximum at 40Mbps (below current rate) I take it this is BT experimenting with lower standard SNR of 3.0 in place of the former 6.0?
I assume that I just leave it alone and do not need to reboot the modem/router?
Interesting to see what happens.
