I thought it was suppose to locked at SNR 3.1dB on G.fast?
Absolutely not.
Why on earth do you think we repeatedly told you about SRA and how it would be far more apparent on the 330 product because you would not have the safety buffer like on the 160 product. Before you decided you decided to upgrade, you said you understood the implications of SRA. It's what made your upstream more variable this time, and it is what affected your downstream speed last time you were on g.fast.
You lied in the other thread and I'm afraid I can't believe that you really think this either, you have been on broadband forums for long enough to know that SNR is a variable figure.
Harsh as it may sound, you didn't listen. Not one single person thought it would be a good idea for you to upgrade.
I am going to cancel G.fast
It was made abundantly clear to you, time and time again that you could not cancel. Even UnchainedISP warned you it would be a bad idea to upgrade. It will have cost UnchainedISP money for you to be upgraded. How is it fair that they should be out of pocket because you ignored all best advice and then changed your mind yet again!
You cannot keep going round and round in circles ordering things then changing your mind constantly leaving other people to pick up the financial costs that you leave behind.
The harsh reality is that everyone else has to live with the consequences of decisions they make.
I suggest the best thing you can do is get rid of the Zyxel modem and
never look at stats again. Stop doing speedtests and just be happy that you have got a g.fast product that many people would still be envious of.
Your life will be a lot happier if you didn't constantly worry about your connection speed. Having a break is the ideal opportunity to hopefully forget all about your connection. Now go enjoy your holiday and put all thoughts about broadband out of your head, because there is naff all you can do about it now and worrying about it wont make a jot of difference to the outcome.
I think I've said all about that can be said, so I'm best locking this thread now before others comment - which they undoubtedly will - and before things get out of hand.
