I originally intended getting FTTC when I moved to Zen (Lite) in November 2011, but by the time I got connected on ADSL and had a new socket & cabling installed, and got a Billion 7800n, I was so pleased with the ADSL (later ADSL2+) I decided to stay with it as stability and reasonable speed was all I needed with working at home.
Some people (me included) got moved last summer because of the olympics, and can't be moved back.
I noticed the difference as slow loading sites and slow to dowload email. It did improve a bit but I still get the slow response for websites and some pages. Interleaving also came on in June, and the noise margin reset early November.
More recently, I think I was moved again in November because although I have the fastest connection/sync I've ever had: ADSL 1092 / 9349 kbps, I still get odd delays with web pages loading and sometimes, slow to download email. It's not terribly slow, but not as fast as it used to be before summer.
My ping also went up from 25 on most Speedtests to 45 most of the time, but the same Speedtest I've always used gives me just over 8 down. (mostly 7.4 before).
My attenuation is 46 down, 28.8 up (pretty much what it's always been: NEALB exch), and the noise margins are on average 2.9 down 5.9 up during the day, 1.4/5.8 at night.
What I'd like to ask is, would my taking up the current Zen offer for installation of FTTC be likely improve the general overall stability and slow loading of websites at times ?
