WRT150N - all lights flashing

I had successfully set up my new WRT150N router and it was working.  But then it just stopped after about 12 hours.  All the lights on the front of the router are blinking.  When I directly connect to the router, my computer can't detect it.  I've browsed through these forums a bit and tried a few things - the reset button (60 seconds), unplugging the router, downloading the EasyLink Connect tool, but I'm still stuck. 
Any ideas what's wrong and how I might fix it?

Re: WRT150N - all lights flashing

You need to try again to reset the router to factory defaults.

To reset your router to factory defaults, use the following procedure:

1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.

If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.

If you cannot get "Reply from ..." in step 9 above, your router is dead.

If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.

If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.

Please let me know how things turn out for you.

Re: WRT150N - all lights flashing

Thanks for your reply.  It looks like my router is dead.  I followed steps 1-9, but am unable to successfully ping the router.  I receive the following error:
PING: transmit failed, error code 1231.
Also, the lights on the front of the router were consistantly flashing throughout the whole process (except when the router was unplugged).
ISP: Broadstripe
Model: WRT150N v1.1
Firmware: ? (I can't connect to the router, so I don't think I can check this)
Does 'dead' mean dead at the hardware level?  Is there any way to fix this, or do I need a new router?  Any idea how this could have happened?
Thanks again for your help.

Re: WRT150N - all lights flashing

if none of those works, try to contact the phone support and ask them to verify if your router could be defective?

"Dead" means that either
1)  The router hardware is defective or
2)  The firmware is defective (or corrupted) and it has locked the hardware into a state where the firmware cannot be replaced.
In either case, the router is useless.  If possible, return it directly to the store you bought it from and get a replacement.  If that is not possible, the router should still be covered under the Linksys warranty.  You will need to contact Linksys tech support by phone.  The tech will want to try a few more things.  If he is unable to get the router working again, then ask him for an "RMA" number, so you can ship the router back to Linksys and get a new one.

Re: WRT150N - all lights flashing

Ive had the same issue. Ive tried updating the firmware, factory resets.


Only think ive found that works is unplugging the power adapter from the back and then plugging it back in.... unfortunately you will need to repeat this over and over and over until it finally comes on. If it double flashes all lights then do it again, if they come up solid then go out and comeback on one at a time it usually means its good.


Once you get it it working.... you pray your power never goes out cause you'll be doing it all over again.

Had the exact same problem with two identical routers!  Turns out that the wall power supply was bad.  Replaced the power supply with the one from the second unit and voila! problem solved.

I had the same problem with my wrt120n wifi router. I almost gave up before finding out that my power adapter is busted. I replaced the power adapter and my wrt120n is now back online Smiley Happy
