This guide came about since I was experiencing issues with my personal home Wi-Fi network. Initially I suspected my iPhone to be the cause of poor wireless performance on my home network due to issues Apple has been seeing with its iOS mobile operating system in the 6.x version range. Not wanting to wait for Apple to fix certain compatibility issues, I decided to investigate my own network to see if the issue could be there. It turned out the issues I was facing with poor Wi-Fi performance was not a fault of my iPhone, but my network.
Therefor I want to share my personal experiences with fine tuning my wireless network for optimal performance - that is, increased throughput (speed) and general performance (radio range). The tips and tweaks provided in this guide are simple to execute and often forgotten even by seasoned tech experts. Even if your network is performing well, these tips should be able to squeeze out some extra performance. Let's cover them one by one, and hopefully by the end, your wireless network is running great once again, or better than it ever has operated.
This guide is going to use a D-Link DIR-855 wireless router as the base for settings and such. Most wireless routers include almost exactly the same settings; they may just be worded differently and found in different locations - just hunt around for them. The first tip right out of the gate is to ensure that your router is running the latest firmware update. Often after logging into your router through its web-based control panel, you can enter the settings area and check that you have the latest firmware version if you're connected to the internet. If not, visit the manufacturer's website and check. It's worth the time as firmware updates can not only fix bugs, but also improve performance and open up new settings.
