My Neotel experience
Posted by Eduard Grebe in technology on 06/11/2009
Updated 6 November 2009.
I just cancelled my Neotel service. Here’s why.
As you can see at the bottom of this post, when I first started posting speed tests on my Neotel connection (it is the high-end consumer offering NeoFlex Data 15GB), I was proactively contacted by a Neotel employee, Albert Goosen. This really impressed me, and I hoped this meant that the non-responsiveness for which Neotel’s client services has become famous would be spared me. Unfortunately it meant no such thing.
From the moment I received my EVDOx1 router from Neotel, the quality of the service disappointed me. At times I got half-decent speeds of 400-500kbps, but more often it hovered in the 50-200 range. And that is an average with the connection dropping to a few bytes per second several times per minute. Worse, every few days, for hours at a time, or even for the whole day, the connection would be highly unstable with speeds averaging less the 100kbps. I though this might be a signal strength issue, so I tried to test the latter with the bundled software. No luck, the CD that shipped with my router could not be read. I hunted around the internet and managed to download a piece of software called “Axesstel Manager” (the modem is manufactured by Axesstel). However, the version I found (apparently the one supplied by Neotel) would not speak to my modem, complaining that I should insert a valid “RUIM”. I gathered that this is a simcard-like item not used by Neotel (but on other CDMA networks) and that other Neotel customers had the same problem. Eventually I managed to find a forum posting on Mybroadband by one reslient Neotel customer who managed to get a technician to provide him with an up to date version of the software that could actually measure signal strength on the NeoFlex routers. In the mean time I had ordered a R600 Poynting cellphone aerial with adapters for the Neotel devices. Once I ran the software, I discovered that my signal strength was fine even before attaching the large outdoor aerial, and the latter improved signal strength only marginally (from an “RSSI” of -75 to about -65).
But my data speeds remained unchanged and at times the modem would even refuse to connect to the Neotel network. Inexplicably, on a few occasions the speeds would be very high (more than 1Mbps) but only for very short periods. And then I’d be back with my dialup-quality “broadband” service. This obviously made for a highly unsatisfactory experience, especially given that I was replacing a 4Mbps Telkom ADSL line with this (in the hope of saving money). All I expected was reliability and speeds within the range advertised by Neotel. It should be noted that I am situated slap bang in the middle of the Cape Town CBD – a prime business market for telecoms. All I can
So I lodged a complaint with Neotel customer care and they promised to get back to me. They never did. I sent an email to complaints@neotel.co.za and to network@neotel.co.za. No response. Then Albert Goosen contacted me on this blog (within a few hours of posting my first speed test — I was highly impressed). This is the email I sent him on 30 October:
Dear Albert
First, let me thank you for contacting me on my website, it is certainly refreshing to be proactively contacted by a representative of a telecoms company. For reference: my username on the network is 0218010210@neotel.co.za
My problem has been that the NeoFlex product I signed up for has delivered significantly inferior speeds to what is advertised (see the email below). In the last day or two, matters have actually improved somewhat, and like on the speedtest I posted, download speeds are now often in the 400-500kbps range. However, it is extremely variable and my fear is related to the two year contract I signed. If matters worsen again to what I was experiencing earlier this week and last week, it is almost unusable for me. So I have been thinking of trying to cancel the contract and rather making use of an ADSL product like I have done in the past. But perhaps you can give me advice as to what can be expected. Further, I wondered whether your Wimax product would provide a superior experience, but unfortunately the WImax packages advertised on your website are prohibitively expensive. If I could subscribe to something like the NeoFlex 15GB package I am on, but use the superior Wimax access technology, that may have been a good option.
I insert below my email to Neotel sent a few days ago and which also refers to a telephonic query I lodged.

Subject: Absurdly bad quality of service in the Cape Town CBD
To: network@neotel.co.za, complaints@neotel.co.zaDear Neotel Network and Complaints teams
(Please note, I logged a call on this issue with customer service, with reference number 101728 and am awaiting feedback.)
I recently signed up for your NeoFlex Data 15GB service. A website coverage check indicated “excellent” coverage at my address. (An Altech person also physically checked coverage at my flat and it was apparently fine.)
However, I experience extreme variability in download speeds (ranging from a few bytes per second to a maximum 20KB/s or approximately 200kbps it probably averages around 100-150kbps at most). This is compared to the advertised peak download speed of 3.1 Mbps and average download speeds of 450-900kbps. I have purchased an external aerial in the hope of improving my experience. This slightly improves my RSSI values from -75 to about -65, but has had absolutely no effect on download speeds. Since these scores in any event apparently reflect fairly good signal strength this is unlikely to be the problem. I cannot but conclude that this is an issue with the quality of the service — either the number of users using the base station, backhaul capacity or a similar issue. In any event, it is an entirely unsatisfactory user experience and is significantly inferior to what is advertised for this product.
This has been a severe disappointment, as I was planning to replace an ADSL connect for my home office with this product. The disappointment is especially acute given that I had no reason to suspect that a product aimed largely at business customers in the central business district of a major service could possibly be so unreliable.
Could you kindly indicate whether there is any chance of improving my experience, and if not, how I can go about nullifying the contract which I have signed with Neotel.
Kind regards
Eduard GrebeOnce again, thank you and I look forward to your response.
Unfortunately, I received no response to this email. So, what could I do? I cancelled my service.
Original post. Here are the speed tests I conducted (keep in mind that when my connection was down or very slow I couldn’t even conduct these tests, the page would take too long to load):






en_ZA in Ubuntu is fucking broken
Posted by Eduard Grebe in technology on 07/07/2009
One of the greatest irritants in Ubuntu is that the English (South Africa) dictionaries are totally pathetic. I always have to switch the document language in OpenOffice to English (UK) for the spell checker to work properly. In Evolution it’s just useless.

But one doesn’t want to switch your locale, because then you’d have to deal with (to me) meaningless imperial units and the Pound as default currency.
I should just check out the localisation effort myself and bloody well merge the en_GB dictionary into the en_ZA dictionary if necessary.
HTML5 video tag
Posted by Eduard Grebe in technology on 04/07/2009
It’s really important to support open video on the web. Currently the best way to do so is to embed Ogg Theora videos using the new HTML5 video tag. It’s supported by Firefox 3.5. I’m posting this code snippet by Michael Verdi and based on Kroc Kamen’s Video for Everybody mostly so I can easily find it again. It involves using the video tag but also fallback options (flash etc.) for browsers that don’t yet support it.

Own your books!

I just bought a Sony ebook reader – it’s great (and unlike the kindle reads the open ePub format). But it’s extremely difficult to get books without DRM for it (only US out-of-copyright books are really available). After the long fight over DRM in music, I can’t believe the publishers are trying the same thing! Why would one buy a book you can’t even be sure you’ll be able to read in a year or two’s time?
(I bought it mainly to read papers, documents, etc. in PDF but the old books are nice.)
Amazon and other e-media aggregators know that digital text is the irrational exuberance of the day, and so are seizing the opportunity to codify, commodify, and control access for tomorrow. But access doesn’t “look and read” like printed paper at all – just ask any forlorn investor. Access is useless currency.
Why is this important? Because Kindle is the kind of technology that challenges media freedom and restricts media pluralism. It exacerbates what historian William Leach calls “the landscape of the temporary”: a hyper mobile and rootless society that prefers access to ownership. Such a society is vulnerable to the dangers of selective censorship and control.
Digital rights management DRM, which Kindle uses to lock in its library, raises critical questions about the nature of property and identity in digital culture. Culture plays a large role – in some ways, larger than government – in shaping who we are as individuals in a society. The First Amendment protects our right to participate in the production of that culture. The widespread commodification of access is shaping nearly every aspect of modern citizenship. There are benefits, to be sure, but this transformation also poses a big-time threat to free expression and assembly.

Nice to see Mark and Ubuntu getting some recognition. And much as we love free software, we have to admit that the key challenge is sustainability. Certainly Richard Stallmanesque fundamentalism is not going to change the world. Until Ubuntu is as good as the Mac *and* making money, we won’t know that free software desktop operating systems have a future.
Many open-source companies give away a free version of their software that has some limitations, while selling a full-fledged version along with complementary services for keeping the software up to date. Canonical gives away everything, including its top product, then hopes that companies will still turn to it for services like managing large groups of servers and desktops instead of handling everything themselves with in-house experts.
Canonical also receives revenue from companies like Dell that ship computers with Ubuntu and work with it on software engineering projects like adding Linux-based features to laptops. All told, Canonical’s annual revenue is creeping toward $30 million, Mr. Shuttleworth said.
That figure won’t worry Microsoft.
But Mr. Shuttleworth contends that $30 million a year is self-sustaining revenue, just what he needs to finance regular Ubuntu updates. And a free operating system that pays for itself, he says, could change how people view and use the software they touch everyday.
