Unlike most on here a didn't notice any change in my broadband when it switched from ADSL24 I've had a few months of fault free service . It runs at 6.8mb to 7.1 and has been very stable ping test is usually grade A . Today I found it slow for the first time I can't find any local reports of faults on bt and tt service status pages. My router looks good connecting at 8128 as usual snr is unchanged.
So will wait to see if it corrects itsef .
