About every second day now, my ADSL broadband connection turns to sludge. Just loading the ABC news homepage, or BBC, or anything else, takes up to a minute, or sometimes stalls indefinitely.
Power cycling the ADSL modem sometimes fixes this problem, and also the times when DNS stops working, i.e. the stall is during "Looking up ...". I just did that now, without improvement, but hitting the "Reload Current Page" icon in firefox sometimes helps.
In firefox, I have network.dns.disableIPv6 = "user set boolean true", but that's more for slow "Looking up ..." AIUI, whereas it's glacial page transfers which make the service almost useless at the moment.
The link looks more than OK:

Lousy attenuations. s/n consistent with 1.5Mb/s rates. Which exchange are you on? I have a daughter on Moreland and she is also having poor performance. Internode "converted" all the 1.5Mb/s ADSL-1 over to unthrottled some months ago, and the soeeds should have gone up to 8Mb/s (max). I now get around 7, with a downstream noise margin of 6.3 dB. My daughter gets 1.5, unchanged, but hasn't chased it up. It isn't the modem - I took a spare one I had checked on my line and it also ran at 1.5Mb/s. She has much better attenuation than I do.
