It’s been a bit over two and a half months since I rolled my car on an icy corner on the way to the last day of PyCon Au 2013. My body works properly again modulo some occasional faint stiffness in my right side and I’ve been discharged by my physiotherapist, so I thought publishing some retrospective thoughts might be appropriate.

I Want My… I Want My… NBN

I thought I’d start this post with some classic Dire Straits, largely for the extreme tech culture shock value, but also because “MTV” has the same number of syllables as “NBN”. I’ll wait while you watch it.

Now that that’s out of the way, I thought it might be interesting to share my recent NBN experience. Almost a year ago I said “Yay NBN! Bring it on! Especially if I don’t get stuck on satellite”. Thankfully it turns out I didn’t get stuck on satellite, instead I got NBN fixed wireless. For the uninitiated, this involves an antenna on your roof, pointed at a nearby tower:

An NTD (Network Terminating Device) is affixed to a wall inside your house:

The box on the left is the NTD, the box on the right is the line from the antenna on the roof. Not pictured are the four ports on the bottom of the NTD, one of which is now plugged into a BoB Lite from iiNet. According to the labels on the NTD, the unit remains the property of NBN Co, and you’re not allowed to tamper with it:

Getting online is easy. Whatever you plug into the NTD just gets an IP address via DHCP – there’s none of that screwing around with PPPoE usernames and passwords. The BoB Lite lets you configure one of its ethernet ports as a “WAN source” instead of using ADSL, which is what I’m doing. Alternately you could plug in a random Linux box and use that as a router, or even just plug your laptop straight in, which is what I did later when trying to diagnose a fault.

The wireless itself is LTE/4G, but unlike 4G on your mobile phone (which gets swamped to a greater or lesser degree when lots of people are in the same place), each NBN fixed wireless tower apparently serves a set number of premises (see the fact sheet PDF), so speed should remain relatively consistent. Here’s the obligatory speed tests, first from my ADSL connection:

And here’s what I get via NBN wireless:

Boo-yah!

Speaking as someone who works from home and who has to regularly download and upload potentially large amounts of data, this is a huge benefit. Subjectively, random web browsing doesn’t seem wildly different than before, but suddenly being able to download openSUSE ISOs, update test VMs, and pull build dependencies at ~2 megabytes per second has markedly decreased the amount of time I spend sitting around waiting. And let’s not leave uploads out of the picture here – I push code up to github, I publish my blog, I upload tarballs, I contribute to wikis. I’ve seen too much discussion of FTTP vs. FTTN focus on download speed only, which seems to assume that we’re all passive consumers of MTV videos. OK, fine, I’m on wireless and FTTP is never going to be an option where I live, but I don’t want anyone to lose sight of the fact that being able to produce and upload content is a vital part of participating in our shiny new digital future. A reliable connection with decent download and upload speed is vital.

Now that I’ve covered the happy part of my NBN experience, I’ll also share the kinks and glitches for completeness. I rang up to get connected on August 1st. At the time, the next available installation appointment was August 21st. On that day I got a call saying the technician wouldn’t be able to make it because his laptop was broken. I offered to let them use my laptop instead, but apparently this isn’t possible, so the installation was rescheduled for September 6th. All attempts at escalating this (i.e. getting the subsequent 2.5 week delay reduced, because after all it was their fault they had a broken laptop) failed. By the time the right person at iiNet was able to rattle enough sabres in the direction of NBN Co, the new installation date was close enough that it didn’t make a difference anymore. To be clear, as far as I can tell, iiNet is not at fault; the problem seems to be one of bureaucracy combined with probable understaffing/overdemand of NBN Co (apparently this newfangled interwebs thingy is popular). As an aside, I mentioned the “broken laptop” problem to a friend, who said a friend of his had also had installation rescheduled with the same excuse. I’m not quite sure what to make of that, but I will state for the record that I seriously doubt our new fearless leaders would have been able to make matters any better had they been in power at the time.

Anyway, installation finally went ahead and all was sweetnees and light for just under three weeks, until one of those wacky spring days where it’s sun, then howling wind, then sideways rain, then sun again, then two orange signal strength lights and a red ODU light:

ODU stands for Outdoor Unit, which is apparently the antenna. For at least an hour, the lights cycled between red and green ODU, and two orange / three green signal strength. Half an hour on the phone to iiNet support, as well as plugging a laptop directly into the NTD didn’t get me anywhere. I managed to get a DHCP lease on my laptop very briefly at one point, but otherwise the connection was completely hosed. The exceptionally courteous and helpful woman in iiNet’s Fibre team logged a fault with NBN Co, and I switched my ADSL – which I had kept for just such an emergency – back on, so that I could get some work done.

The next day everything was green, so I plugged back into the NTD. About an hour after this, I got a call from the same woman at iiNet saying they’d noticed I had a connection again and had thus cancelled the fault, but that she was going to keep an eye on things for a little while, and would check back with me over the next week or two. I also received an SMS with her direct email address, so I can advise her of any further trouble. I’ve since got smokeping running here against what I hope is a useful set of remote hosts so I’ll notice if anything goes freaky while I’m asleep or otherwise away from my desk:

I really wish I knew how to get a console on the NTD, or view some logs. I was told it’s basically a dumb box, but surely it knows a bit more internally than it indicates on the blinkenlights. As I said on twitter the other day, I feel like a mechanic trapped in the drivers seat of a car, with access only to the dashboard lights. Oh, well, fingers crossed…
