Thanks but my area never experience slowest than Watford but I do feel painful for those living in Watford area.
My router was healthy max rate 222/37 but capped at 159/29 - which it perfectly fine don't think it will ever reduced that and worsen than Watford lol. Gfast got vectoring and at present CRC, ES, SES are zero since day 1 of installed, very clean bill.
But it so strange from checking of btw and ofcom site, they estimated lower of 189/183 while the router stats 222.
Have a good day everyones.
