Linksys WRT1900ACS

Linksys upgraded one of their top routers, the WRT1900. The latest version is called WRT1900ACS. This is the second installment with faster processors and faster results. The 2.4GHz band has a theoretical throughput of 600 Mbps, while the 5.0GHz band has a theoretical throughput of 1300 Mbps. Here’s one good review from PCWorld.

How To Setup Client Bridge

I have an old Linksys WRT54GL router flashed with an open-source firmware DD-WRT. One of the nice things you can do with DD-WRT is configure it as a client bridge. You can then use the client bridge to connect a computer with no wireless network interface to the network. This article was written to help me remember in the future how to setup a client bridge on a Linksys WRT54GL flashed with DD-WRT. The configuration details pertains more to me and may not necessarily work out for your setup. If you want a more complete instruction, check out the client bridge documentation available from DD-WRT’s website.

  1. Reset the router. Login. Set username and password.
  2. Go to Wireless > Wireless Security. Set security mode and key to match your AP.
  3. Go to Wireless > Basic. Set wireless mode to Client Bridge.
  4. The wireless mode and SSID should be the same as your AP.
  5. Go to Setup > Basic setup and manually set IP address.
  6. Set IP address to Leave local DNS blank. Main router is
  7. Go to Security > Firewall and disable SPI firewall and only multicast checked.
  8. Go to Setup > Advanced Routing. Change mode from gateway to router.

DD-WRT To The Rescue

I got a Linksys WRT160N wireless router with a wireless problem. It’s not good when a piece of hardware no longer function the way it was intended to. I can’t get my laptop connected to it even if I’m literally 3 inches away from it. Instead of throwing away the router, I’ve decided to install a third-party firmware called DD-WRT.

It was a little unsettling at first because installing a third-party firmware can potentially brick a router if I don’t do it correctly. But, since the router is already useless, I’ve decided to install DD-WRT. Just as a word of caution. If you decide to install DD-WRT, make sure your router is supported. Read up. Do your homework. And follow instructions.

Suffice to say, the wireless router firmware upgrade was successful. The router is functioning nicely. DD-WRT will give you router functions you normally see in enterprise equipment, but the biggest improvement is, I now have a router with a much stronger wireless signal. Linksys sets their routers to transmit power at about 40mW. The DD-WRT firmware allows you to change the transmit power from 1-251mW. Mine is set to the DD-WRT default, which is about 70mW.

In addition to increase signal, you can also set the router as a wireless client, a wireless client bridge, a wireless repeater, and a wireless repeater bridge. Awesome. If you have an old router that’s misbehaving, you might want to look into the DD-WRT firmware. You can breath new life in an old wireless equipment.
