As did I.  I was wondering if they targeted me as I’m in the process of installing a NBN FTTN connection on a month-by-month trial to see if it’s any better.   Obviously it was a general marketing email then.

I’ve found all the speed test sites extremely variable.  I don’t bother with them much these days.  My VDSL2 modem connects at 33/2.8 and I usually get around that for downloads, depending on where they come from.  The poor rate is due to my connection having to go through two intermediate nodes before ending up at a supernode. 

For the non-Canberrans here, the Transact/iiNet (now owned by TPG) VDSL2 network is based off the old Transact VDSL network that was installed around 15 years ago with new cable installed (back then) on above ground power poles.  It’s basically FTTN, where the nodes are no more than 300m from a customer’s house, then multiple nodes are linked via fibre back to “SuperNodes” and then back to the main data centre.

However, apparently the VDSL2 DSLAM cards were too big for the node cabinets so were only installed into the supernodes.  Along with the fibre runs between supernodes and nodes there are apparently a number of copper pair runs as well so if you aren’t near a supernode, they jumper the copper pair from your house, to one of the link pairs, and so on until you get connectivity to a supernode.  In my case that’s something like 900m in total distance through two intermediate nodes.

iiNet announced last year that they were rolling out micro-dslams into the nodes to fix this, but I’m still waiting.  They have fallen completely silent about it, and I’ve not heard of anyone getting upgraded in the past 12 months.

Yes I get 33Mbps down, but only 2.8Mbps up and the reliability recently has plummeted again.  I’m getting increasing packet loss and ping spikes.  Last time this happened it took months and multiple technician visits to get it working again.  It doesn’t help that the call centre is in South Africa, and the local technical support is contracted out as well, each with their own job tracking systems that don’t appear to talk.  iiNet also don’t seem to be answering emails anymore.  I’ve sent in a number with no response.

NBN FTTN was made available here in the past couple of months so rather than keep flogging the iiNet dead horse I’m going to get it installed and see if it’s any better.


Carl.
