In one of my recent articles, I explained how I set-up a guest wireless network for our work place (after getting it to work with the right wireless channel )
After configuring the guest access point, I set up the DNS servers to point to OpenDNS in order to provide a safer and faster DNS service (compared to the default DNS servers our ISP provides) as well as choosing what web-sites should be allowed on the network.
For example, bandwidth hogging (Media/Video Sharing) and other web-sites which could potentially be used for illicit purposes (P2P/File Sharing) are forbidden on the network.
DNS-O-Matic is a free service provided by OpenDNS. With DNS-O-Matic, you can propagate IP address changes across multiple services such as DynDNS, OpenDNS and many others.
With DD-WRT, you can set-up DNS-O-Matic so that your services stay updated with your IP changes as soon as they happen.
This article will very quickly go through the process of setting DNS-O-Matic on your DD-WRT powered router.
Choosing the wireless channel to use on your network can be a real pain in the ass; especially if you live or work (if this is a business network) in a densely populated area.
Put simply, channels are the radio ‘frequencies’ which your devices use, to talk to the router to get on to the internet or on the LAN.
If there are too many routers using the same channel in a close proximity, data sent by your devices can start to experience a slow-down or worse; corruption.
