I was with Exetel for about 9 months, and in the beginning things were okay, but eventually something happened and I started to have periods of congestion. My internet in the evening would max out http downloads/streams at about 50kb/s. As you can guess this makes the ADSL service very useless. It meant if I needed to do some work from home I pretty much couldn’t do so.
Exetel and I parted ways, so I went with iiNet, as I needed a service that if contracted could be changed/moved. iiNet and Internode both could do this, and in the end iiNet won out purely due to it being $10 a month cheaper. So when I move into the new house in ~12-16 months, we will change over to iiNet FTTH service and they will wipe the contract for me to continue on a new contracted service.
Below is the speedtest I performed minutes after I switched out my router/modem settings.
