Linksys WRT54G as a Wireless Repeater Using dd-wrt

Recently, I discovered I had some weak wireless signal in certain areas of my home. My first instinct was check out BestBuy or some other online shop for a Wireless Repeater only to find that I’d be spending a minimum of $90 to get the device. Yuck. Double yuck. I wanted a cheaper solution. Yeah, I might have found something cheaper on eBay, but I was also impatient and didn’t want to wait.

I had this Linksys wireless router kicking around and wondered if someone knew how to turn it into a Wireless Repeater. Afterall, isn’t the technology used to be a wireless router or repeater basically the same? After a quick Google search, I found out there was a solution. Using the dd-wrt linux based firmware. I was familiar with this already as I had used it before on another router to upgrade it after I had read this article on turning your $60 router into a $600 router. So I decided to give it a shot.

Pretty much all of the instructions I needed I found here. Basically you have to:

  • Disable the firewall
  • Choose the network you want to repeat
  • Create a virtual network to connect to

All said and done it took me about 20 minutes to set it all up, mostly because I didn’t want to brick my router, even if it only cost $50 and I wasn’t using it anymore. I’m not a fan of breaking stuff. Anyway, now I have great signal strength no matter where I am in my house, which is key. If you’re having a similar problem, I highly recommend trying this out, especially if you have the hardware lying around unused.

    I have a WRT54G that I want to turn into a repeater…are there a set of easy instructions somewhere for flashing the dd-wrt firmware?

    Hi Michael, I’d just check the dd-wrt web site. I believe that’s where I found the information I needed. Hope that helps.

    Hi Bill,

    good to know that it works. One question I wonder about (before trying to dd-wrt my old WRT54G and obviously being not very knowledgeable in networking) is whether I can still use the ethernet ports for wired connections once the router runs in repeater mode?

    Do you have any knowledge/experience about that?

    Thanks,

    Sebastian

    Hey Sebastian,

    I didn’t try to use the wired ports after I switched it over. My guess is you probably could use them. Won’t break anything to try though.
