Computer problems are frequent and can be difficult to solve.{{Citation needed}} Networking problems in particular can puzzle even seasoned people and sometimes seem to have arbitrary issues causing them. {{w|Network packet|Packets}} are units of data transfer used in computer networking. One measure of network performance is ''lag'', or the more technical term of {{w|Latency (engineering)|''latency''}}, which describes the amount of time it takes for data to travel from one point to another (and perhaps back); saying a packet's transmission is 'laggy' means it is unacceptably delayed. Suffering from lag means that you're likely exhibiting various knock-on effects, from intolerable online gaming experiences to difficulties streaming multimedia resources, with or without the simultaneous issue of having ''low {{w|Bandwidth (computing)|bandwidth}}''.

Lag in packet transmission and other network performance measures can appear quite random. Just to start with, your ISP may be engaged in traffic shaping, which can do very weird things indeed to your packets (making the first megabyte of a transfer faster than any other, for example); now imagine that your ISP's ISP (usually known as an "Upstream Provider") is engaged in something similar, and you begin to see the scale of the problem. Wireless latency can relate to things as unexpected as where people are standing, what they are touching, the weather, viruses and other system compromises, network activity by other unseen users, and so on. Because humans are wired to perceive patterns, they will {{w|Apophenia|find them even in random data}}, a fallacy that Cueball is probably suffering from here. He variously attributes the network behavior he sees to the packet number being even vs. odd, packet arrival time being before vs. after noon, and packet arrival day being today vs. yesterday. Such a pattern would make sense if it were merely "every other packet" regardless of odd or evenness, but that still leaves unexplained the other "patterns" Cueball is seeing.
