Yes how low can a online gamer go? Well here is the answer to a question that has long dominated the world of online gaming "why is my connection so slow?" The answer is either your computer cant handle the game or someone is using one of theses suckers...a lag switch. the ible is all about creating your own so you too can also annoy the hell out of your fellow gamers.
Step 1: Materials
Materials are few in this project. Please note the amount of each item is in the [ ].
- Cat5e Cable (internet cord) 
- Switch, any toggle kind. 
- Soldering Iron and Solder.
- Extra wire.
- Case. [Optional]
Step 2: "Hack" the Cat5e Cable
Carefully open the plastic casing on the Cat5e cable to reveal the inner wires. Be sure NOT to cut any of them other wise this project will not work. Find the SOLID ORANGE wire and separate it from the rest. then when you have enough space cut it in two and strip the wires.
Step 3: Solder on the Switch
Now grab your switch and solder the split orange wire to the switch points as shown in the diagram below.
Step 4: What It Should Look Like So Far...
Kind of a pointless step I know but below is a picture of what your Lag Switch should look like so far.
Step 5: Completion
Congratulations you are done! to use the Lag Switch is quite simple... start an online match, when the game starts or if your being attacked flick the switch into the off position and voila your team and opponents connection will slow or stop completely while you run around killing anyone you please! Finish off your lag switch by sticking it in a case or if your eager to get some well deserved revenge plug one end of the cable to your console and the other to your nearest internet jack and start making those online jerks cry their hearts out! Just a word of warning (I bet you weren't expecting this!), manipulation of the network is frowned apoun by the online community and could get you banned or have your online membership suspended, so please use the Lag Switch appropriately and only when necessary; thanks.
