My Experience of Internet Services in Brazil: W@y Internet

In 2004, I [1] subscribed to an Internet service provided by an ISP called W@y TV in Belo Horizonte-MG, Brazil. This Internet access service was ideal for me and I wish it could have continued forever. Unfortunately, as with all good services [and products] it was relatively short-lived.

This service gave me a download speed of 512 kbps (kilobits per second). I later upgraded to 2 Mbps (megabits per second) in about 2012. This provided an upload speed of 512 kbps, which was a little slow for my re­quirements but certainly sufficed. The great feature of this service was that all list­ening ports were open [2]. Perhaps a few were shut, but none that affected any­thing I wanted to do. The IP (Internet Protocol) address was officially dynamic. How­ever, I never saw it change since around 2008. For all intents and purposes I had the fixed IP: 201.62.140.93. Instead of having to sign in to the service, user valid­a­tion was done automatically by identifying the MAC address of my TP-Link router. I have a suspicion that, a few years into the service, the technicians had simply de­ci­ded, for convenience, to tie my router's MAC address to this IP address, which was nice. The W@y TV tech­nicians, were polite and seemed competent and appropri­ately know­ledgeable. I got on well with them.

Consequently, from July 2008, my monthly bill for the service came from Oi, not W@y TV. Notwithstanding, I think that Oi, although the owner, left the old W@y TV people — at least from a technical point of view — to carry on their service as before. In fact Oi itself offered a competing service. The service provided by W@y TV was by coaxial cable, using a 573 MHz (megahertz) radio frequency carrier for download and a 32,496 kHz (kilo­hertz) carrier for upload. The Motorola Surfboard SB5101 [DOCSIS 2.0 comp­liant] cable mod­em had a top download speed of 38 Mbps, so I had plenty of speed upgrade potential, even if this actual top speed of 38 Mbps was not practical over the existing cables.

My home installation comprises 3 personal computers running Xubuntu Linux, each with a precisely-configured firewall to suit its intended use. The 3 computers are connected to a TP-Link router Model TL-WR741N, which also has a precisely-con­figured firewall with the minimum necessary and sufficient ports forwarded to one of the 3 computers on the LAN. The router is connected to the Internet via the Motorola SB5101 Surfboard cable modem.

I have subscribed to the W@y Internet service for 11 years. The service has worked perfectly with the installation shown above for at least 5 years. The firewall, shown in red on the cable immediately in front of each respective device, is of course really software, which is running inside the device itself.

Although retired, I continue to write articles on many topics which I make freely av­ailable via the Internet to whomsoever would wish to read them. All are on my web site, which is hosted on a server in the United States of America. I also make them available in PDF files, which I share via the eDonkey/Kademlia networks and Gnu­tella/G2 networks. The "fixed" IP address also allowed me to share them via a File Transfer Protocol (FTP) server, which I set up within my own computer.

These eDonkey/Kademlia, Gnutella/G2 and FTP servers within my computer con­sume hardly any bandwidth. On average, my colleagues and others around the world between them download from my computer about a dozen or less article files per day. This amounts to around 5 MB (megabytes) of data uploaded via my 512 kbps upload connection per day. Minuscule. My servers are thus more like trans­ponders than servers. They would certainly never create any traffic saturation prob­lem for the ISP.

How I wish that this tranquil state of affairs could have continued. Sadly, in a letter postmarked 14 July 2015 (followed by two shorter reminders), the ISP Oi, informed me that the old W@y TV & Internet service would cease on 18 August 2015. This, I was told, was because the technology was too old to be continued. Of course, like any service, W@y TV Internet had short periods of downtime. But never anything catastrophic. Its continuity of service was, on the whole, excellent. I had only 4 ser­vice call-outs in 10 years.

This gave me barely a month's notice to find a new provider. Furthermore, although W@y had moved the service to my "new" address on 20 December 2005 (almost 10 years ago) Oi sent all these letters to my old address. As a result, I did not re­ceive them until the beginning of August. I was fortunate to receive them at all. Oi sent no such letters to my present address, to which they correctly send their monthly bills. Thus I was left with barely two weeks to find another ISP.
