− | This comic shows the supposed probability that a guest will be able to connect to the owner's {{w|Wi-Fi}} in graph form. | + | This comic shows the supposed probability that a guest will be able to connect to the owner's {{w|Wi-Fi}} in graph form. Connecting to a new Wi-Fi network typically requires selecting the correct network name on a settings screen, then entering a password. |
− | The graph starts with tech-illiterate people who don't even know how to control their Wi-Fi connection ("can't find wifi settings"). This group has slightly lower than normal probability of connecting successfully, since they would not know what to do if left alone. However, they still have a reasonable chance to connect as long as someone is available to help them. Once the initial setup is done, they can continue using the connection without any technical knowledge or intervention. | + | The graph starts with tech-illiterate people who don't even know how to control their Wi-Fi connection ("can't find wifi settings").

The vast majority of the population falls into this category. This group of users have enough knowledge to be able to connect and are then satisfied with the connection just working. Since networking devices use a standard protocol to communicate, users typically will not experience any issues. |
− | Finally, the large drop in the graph on the right-hand side is explained by "something involving the word 'firmware'". | + | Finally, the large drop in the graph on the right-hand side is explained by "something involving the word 'firmware'". Firmware is programming which operates a device at the lowest level, typically stored in a {{w|ROM}} or an EEPROM/flash. Modifying the firmware can have certain benefits, for example to gain features that aren't included in the base product. However, understanding and patching firmware requires a great deal of technical knowledge, and can be quite risky for people without experience. Not all custom firmware will interoperate correctly with all devices. In the worst case, installing the wrong firmware or any errors or glitches in the process can even leave devices "bricked" (inoperable and unrecoverable). It's likely that the sharp dropoff in the graph is caused by inexperienced users who know "just enough" to want to modify their firmware, but don't know enough to do so safely. Particularly for users whose connection was already working fine but nevertheless want to experiment with new firmware, their changes often end up worsening their chances of connecting. |
− | The title text indicates that the curve recovers once users are more experienced, and ''can'' consistently install firmware correctly to get a working connection. In such case, the users are able to enjoy better connections through their firmware changes while avoiding their pitfalls. These experienced users are often able to diagnose and fix connection issues through the appropriate use of firmware, making their chances of connecting even better than the average user. | + | The title text indicates that the curve recovers once users are more experienced, and ''can'' consistently install firmware correctly to get a working connection.

− | + | These computer issues have previously appeared in several xkcd comics, notably [[456: Cautionary]], where WiFi problems specifically are mentioned in the title text. | |
− | + | The apparent paradox of people knowing more about a subject also having more problems with it is also explored in [[1760: TV Problems]]; in the title text, the ones who are more likely to die from a skydiving accident are the ones who know the more about skydiving safety, but that is of course not because they cannot make it work, but rather because they make many more dives than regular people, thus increasing the overall risk in spite of their competence. | |

Then it increases slightly and stays almost stable on a long flat plateau before it falls off fast towards the right. Each axis ends in an arrow and has a label to the left of the Y-axis and below the x-axis. Over the curve there are three labels, pointing with one arrow to the two rising and falling parts, and three arrows to the center label above the plateau.] |
