As this is the general forum, I'll post something regarding internet connections as it may help others on ADSL or ADSL2+.
I won't mention the company I'm with, but here's a story of massive stress.
The internet kept dropping out, I would get a red light on the modem and it would disconnect regularly and my speed was akin to dial-up when it did.
Prior to this, everything was perfect.
The first test is to dial 1 on your home phone and see if there's any noise, you should not hear any noise at all.
I could hear crackling, so got Telstra out and the guy put in a brand new line to the house and a new terminal box.
No noise!
So away I went and still the net kept dropping out and slow.
Replaced the filter / splitter, as these have a lifetime as well.
No change.
Replaced the line from the socket to the modem.
No change.
Threw out my modem, as these also have a lifetime and bought a new good quality one.
No change
I knew exactly what steps and questions my ISP would ask, because I have done this for previous clients in the past and wanted to shortcut the to and fro, as you never talk to the same person.
Posted the problem and modem log on their forum, and within an hour they changed a setting and all is well.
It appears that technicians sometimes mix up or mess up settings when setting up new connections for other people.
There was a problem with the line to the house, but that wasn't the problem, the splitter/filter was fine and so was the line to the modem, in fact I miss my old modem, but there you have it.
It was them, not me.
For others, go through the steps I did still, I always keep a spare filter, spare modem and spare line to the modem. You can pick them up cheap.
Unless you hear line noise when you dial 1, contact your ISP via forum, not phone and you'll get a much better response, make sure you post a log from your modem and tell them what steps you've already done.
Hope this helps.
