However, I am aware that some older firmware versions were lower than this.Ĭheck to see what your transmission power is set at by visiting the Wireless –> Advanced Settings page under the title TX Power. Transmit (Tx) power on newer DD-WRT firmware is already set at an optimum level of 71mW.Windows Update for Windows machines is a good place to start. This one may be trivial but there are many people who do not have the recommended firmware for their DD-WRT powered boxes.Īnother thing to check for is up-to-date drivers for your wireless card.
This leaves the user with several other channels which can be used. In this example, you can see that the most saturated channels are 1, 10 and 11. I personally find Site Survey easier to use. If you go to the Status –> Wireless page, you have two options there. The interface isn’t so pretty and you don’t get nice graphs but the information is still very similar. In essence, all you are doing is scanning the wireless spectrum in the place you are planning on using the wireless access point and choosing one which channel is the ‘cleanest’… i.e., the one which has the least number of access points broadcasting on it.If you do not have a laptop handy or do not want to go through the hassle of setting up a wireless spectrum scanner, you can also do pretty much the same thing straight from inside DD-WRT. I will not talk about wireless channel selection so much as I have already written up an article detailing how best to choose your wireless channel.Please note that there are other things you can do to improve signal strength such as purchasing a higher-gain antenna or placing your router in a more central position but these are not limited to DD-WRT routers and thus outside the scope of this article. The ones I will talk about today are as follows (in order of usefulness and ease): This article will be about making use of the features that DD-WRT provides out of the box, as well as some other ‘hacks’ we can use to boost the wireless signal in your home or office. If you have a DD-WRT powered router then you already know how powerful and feature-full it is, compared to a standard out-of-the-box ISP provided router.
