Actually I am confused to give the right title in this article, but hopefully you can understand it from the explanation I gave. At this time I will discuss about internet bandwidth that is not suitable than what I should get from an ISP.

Previously I had a similar article but it was not uploaded because the bandwidth at that time was only 10 Mbps, so it wasn’t optimal for this discussion. For this reason, when I want to make this article, I look for higher bandwidth first and finally it can also use bandwidth Up To 500 Mbps to download and upload. Why do I use the word Up To? only to ensure that later if there is a difference that is not far from 500 Mbps, I will not question it.

A few introductory paragraphs before I go to the main destination.

Next, I take an example from an ISP :




If you look at the 3 images above, the highest speed is offered by CBN, which is Up To 1 Gbps. Before I discuss further, I emphasize the test here is about the speed of bandwidth, regardless of the stability and other things.

The decision to take internet bandwidth services is generally tailored to the needs, including :

  1. Use of the internet
  2. Number of users

In point number 1, this is relative, whether it is used only for browsing, online games or work, because in general, a good salesperson will first ask the needs of prospective customers, so they can provide the right direction.

For point number 2, generally prospective customers do not take this into account and will only complain if the connection is slow which unconsciously has been used by people around him simultaneously. For example, I take 10 Mbps of bandwidth, which if I use it myself is more than enough, but if my family / colleagues use it at that time, of course it will decrease because the bandwidth is divided into them.

Actually there is an additional point that is rarely calculated, namely the device used for internet connections, such as routers, access points (AP), switches and our own devices, including laptops and mobile phones that are commonly used. If you connect a network device with a different speed, then the connected device such as a PC, laptop or HP will be limited by the device.

Where is the influence? If you take services below 50 Mbps, this can be ignored, but if you use 50 Mbps services or above, this should be taken into account.

Topology, this is the most important point, because if you know this topology, it will make it easier in the checking process if there are obstacles. Make sure you pay attention again or ask when installing the internet at your place.

If your service already uses a Fiber connection, generally there will be a media converter such as BDCOM, ONT and the like installed in your place that can function as an internet source or just media so there must be an additional router. The point is the ISP will usually provide the device according to the service you are using.

Example of one of the ONT devices

Before conducting an experiment, I will explain the bandwidth and service topology that I use.

Bandwidth = Up To 500 Mbps

Connection type = Broadband

Topology = ISP <-> My device

<-> = cat 5 LAN cable

According to the topology image above, the ISP only gives me an Ethernet cable to connect to my device, so the internet source will later be my own device such as a router or laptop.

Is it clear enough here? Hopefully, hehehe.

Okay I have done a simulation and to make it easier to make the tab :

Type Spesification Port Local (Mbps) International (Mbps) Conclusion
Download Upload Download Upload
HP 240 G6 i5 7200U / 8 GB Gigabit 467 314 297 263 OK
HP 240 G6 i5 7200U / 8 GB USB Fast Ethernet 88 95 problem with USB device
Asus X455LJ i3 5005U / 8 GB Gigabit 435 424 OK
Lenovo G40 i5 5210U / 4 GB Gigabit 301 311 293 148 problem with RAM

Table results above the bandwidth of close to 500 Mbps from laptops that use Gigabit ports and 8 GB RAM, besides that are far from expected. For USB Fast Ethernet, I only use it as a comparison enhancement, because the HP 240 G6 only has 1 Ethernet port. Oh yeah, in this case I don’t really consider the upload issue if it’s not appropriate because in my opinion almost most internet users download more than upload.

Why international traffic also doesn’t reach ? Please remember, almost all ISPs that offer internet if they do not mention the bandwidth path, it is certain that it is local bandwidth, why ? because the ISP must pass the IIX line which is actually for use in Indonesia, while for the international link (IX), they must have cooperation with other ISPs outside Indonesia (Upstream).

Remember, I adapted to the title of this article, so I only did a speed test to make sure the internet speed I was using was appropriate. This is also the main point before later finding other problems that can be reported to the relevant ISP.

Hopefully until here you can understand it first, because if you don’t understand it, it’s probably rather difficult to understand the next article that will relate to many devices.
