currently waiting on a callback from level 2 at Telecom, but I thought I'd seek opinions here
Last night my DSL link status was struggling to stay up for more than 5 minutes at a time. It stabilised around 11:30 at about 2.5Mbps line speed, but with high loss of signal and error second stats. I have tried this with two routers, an ancient dynalink that can only do ADSL1, and Linksys that can do 2+.
Up until yesterday morning my line speed was 12-13Mbps.
Heres the odd thing. When the phone is offhook and I'm on a call (to the broadband callcentre for instance) the line speed goes back to normal.... Only one landline in the house, and it has a filter on it (tried a different one, even) and a monitored alarm with Chubb, who tell me they've seen nothing odd on the connection.
Dialtone sounds crackl-ier than normal, so I'm convinced its some sort of line fault that appeared yesterday.
People who know more about this than me - any guesses?
edit: we're urban - in Auckland city (probably the Mount Roskill exchange)
