    Stupid question, but have you tried resetting your router? I highly recommend pressing and holding the reset button for at least 1 minute. Also, was your router working prior to trying to upgrade the firmware?

Understand that what you are trying to do, may permanently turn that router into a piece of trash. Firmware upgrades are hit and miss, and sometimes even doing everything correctly will result in a "Bricked" router. A bricked router is one that is about as useful to a computer as a brick. Proceed at your OWN RISK!

Read all directions BEFORE you try anything! First D/L the correct firmware for your router. Then D/L TFTP.EXE from the DD-WRT site. Put these files right on the desktop where you can find them and unzip the firmware. (I am assuming you are running Windows XP)

Now connect your router to the computer you are using with an Ethernet cable and plug in the power. DO NOT TRY THIS VIA WIRELESS!! Then you need to set your computer to a fixed IP address, Open your network connections (control panel - Network Connections) right click your local area connection and select properties. Highlight Internet Protocol(TCP/IP) and again select properties. Under the General Tab select "Use the following IP address" enter 192.168.1.99 Under Subnet mask enter 255.255.255.0 Click OK and wait for the TCP/IP connection to be established. The router first must be reset to the factory default configuration BEFORE you flash it.

Resetting the router means, with the router plugged in to a power source hold down the reset button (on the back of the router) for 30 seconds, then pull the power but continue holding the reset button for another 30 seconds. Then WHILE STILL HOLDING THE RESET BUTTON, plug the power back in and hold it for another 30 seconds. Now you can let the button go and allow the router to reboot.

If you still have only the power light blinking, try pinging the router. Open a command prompt, (Start RUN CMD [Enter]) and type PING -t 192.168.1.1 Leave this window open and dbl-click the TFTP.exe program. There are three empty boxes in the TFTP program. Enter the IP address of the router in the server box (192.168.1.1) enter ADMIN (all lower case) in the password box and click the dots next to the file box, browse to your desktop and select the firmware image you downloaded (.BIN)

Now if your ping command is only returning "Request Timed Out" try resetting the router again only this time watch the ping window for a response from the router. If you get a response, immediately click "upgrade" on the TFTP window. If all goes well you should get an "Upgrade Successful" message. This step is important!! RESET THE ROUTER again after waiting 10 minutes. Now if the router was not initially reset to the factory default configuration before someone tried to upgrade the firmware, it is possible that the router is hanging while it tries to boot and the firmware image was corrupted. If that is the case then you will need to read the DD-WRT Wiki under "Bricked Router". Good Luck!!

Client Mode or 2nd Wireless Router with new Subnet Mask?


The original firmware does not have this option, but you can get a custom firmware at http://www.dd-wrt.com/

DD-WRT is not supported by linksys, so a little caution there as this could ruin your router if it is not installed properly. Fortuately they have plenty of documentation on installation and troubleshooting if needed.

Connection Drops . wrt150n disconnecting


This is a firmware issue with the newer Linksys routers, and most people are having the same issue. Don't expect a stable firmware release from the manufacturer any time soon.

Instead, if you want to fix the problem properly, head on over to www.dd-wrt.com and install their firmware. I did this in a last ditch effort before throwing out my router, and now the router hasn't acted up for more than 10 days.

Be sure to follow the instructions when flashing firmware, several of the steps are critical to not "bricking" your router. As usual, make sure you are on a WIRED connection, as flashing from a wireless connection is guaranteed to kill your router. When flashing dd-wrt's firmware, you must also first flash a "mini" or "micro" version before flashing the full version.

My linksys wireless-g router hangs up all the time and I m ust power on and off to get it to reconnect


Hello,

I even have experienced such kind of problem. To fix this problem all you have to do is to download a new firmware, which is an opensource firmware from DD-WRT it has much more features than the ordinary firmware and its much more stable.

Then after upgrading just make sure that you put the option for Keep Alive enabled and try and restart the router like once per day so that it does not clog up.

That will solve your problem. The DD-WRT website is www.dd-wrt.com

Have a good day.

Bridge or Repeter mode.


It is possible but you will need to flash the router with custom firmware.

Here is how:
http://www.dd-wrt.com/wiki/index.php/Installation

This is only possible if you have two wrt54-g routers that are of one of these types:

WRT54-G ver 1
WRT54-G ver 2
WRT54-GL

(there is a sticker on the bottom that can tell you what version it is)

This is the article that I followed and it workes great.

Repeater router responds with 'Address not found...'


You need to start from scratch.

Whenever you need answers they can be found here -
http://www.dd-wrt.com/phpBB2/viewforum.php?f=1&sid=785382853553ee7844cfab78da0607db

But best to start with the Wili - http://www.dd-wrt.com/wiki/index.php/Installation

And here is your get out of jail card -
http://www.dd-wrt.com/wiki/index.php?title=Recover_from_a_Bad_Flash

If you have to resort to the hard method of recovery, be careful.
I have only ever permanently killed one router - doing this - http://voidmain.is-a-geek.net/redhat/wrt54g_revival.html

You will first need to establish which model router you have. Then you will (assuming you want to use DD-WRT firmware) need to flash a micro or mini firmware. Then you flash again, using the standard.
There are many users worldwide using your WRT54G and GL routers with other than standard firmware, me included. I manage a network of 9 routers running DD-WRT V23SP2 standard.

Don't give up, and when it says to leave it 30 seconds (or 2 minutes) DO! Be patient...

Router to use as relay.


Linksys WRT54GL with DD-WRT firmware. Now, DD-WRT will void the warranty, but it has been incredible for my uses when configuring WDS. A the WRT54GS has also been said to be an excellent router, but I cannot say.
