Some common router settings can be adjusted to optimize your Internet connection. Wireless channel, quality of service and DNS settings can have affect both wireless network experience and your Internet experience.
Note that the below suggestions are intended for customers familiar with making changes in their routers and networking components. If you are not comfortable with these steps, we recommend contacting your network equipment manufacturer for assistance.
- Change your wireless channel to a less congested one
If you live in a dense residential area, you may be able to see other wireless networks around you. It is usually advisable to try and stay on a separate channel from them to avoid interference and noise on your wireless network. The 2.4Ghz spectrum used for 802.11 is divided into 11 channels in the US. Each channel is 22Mhz wide, and offset by 5Mhz to the next channel. Because of this, there is overlap on neighboring channels. Channels 1, 6 and 11 are commonly recommended as they have no overlapping frequencies. Details on changing the wireless channel setting can be found in the user manual for your router. In some cases, you may need to update your wireless router's firmware. Check with your router's manufacturer to verify that the latest firmware version is installed.
- Disable QoS (Quality of Service) if you are not using this service for priority traffic routing
QoS helps police the traffic on your network letting more time-sensitive or critical traffic take priority over non-critical traffic. A common example would be VOIP traffic. Details on disabling your QoS setting can be found in the user manual for your router.
- Change DNS servers to improve name resolution
Domain name servers (DNS) are distributed databases used to translate the domain name (URL) into the server’s true IP address. Some DNS services are better than others depending on your location and the domains being accessed. The two DNS services below are free that can be used in your router setting.
- OpenDNS (primary 220.127.116.11 | secondary 18.104.22.168)
- GoogleDNS (primary 22.214.171.124 | secondary 126.96.36.199)
- Remember to keep your existing ISP provided addresses for reference, in case you want to revert back.
