Since I have moved house my modem always connects to Aligned BSCC 19. 100% Signal no issues with gaming or browsing/downloading. Today its been Jumping from 19 to 20. Once that happens I cannot even connect I get 100% Frame Error Rate and the signal jumps from 0% to 100% after a while ( I have not moved the modem) Aligned BSCC 19 comes back and everything works fine again.
Any ideas why this is happening its only been today.
Thanks in advance
Update 1: Jumped backed to BSCC 20 21:21
Update 2: Back to BSCC 19 21:45
