    I believe my v3 router running OpenWRT has crashed and died. :(

    I tried getting into failsafe mode by the instructions from OpenWRT, but that only worked 1 time. Since rebooting, I can't even ping it now. I think I might have to try to debrick it somehow. Has anyone been successful doing this via shorting some pins on the flash? I mean successful with a v3 router. I've heard it is not the same pins as the earlier versions (1.0/2.0).

    The power light just blinks and the DMZ light comes on for a second or so, then off, then back on again.

    Any suggestions?

    i have a wrt54gv2. i tried to debricked i did the earthing of pin 16

    1first you have to get some kind of metal wire like copper this works best. and unplug the router

    2type in the command prompt ping -t

    3 then touch the middle of the top of the antenna on the left antenna at the same time touch the other end with pin 16 on the flash chip. (you determine this by looking at the wrt fomr the front.)

    if that does not help keep trying. it took me 17 days to get my dead wrt to rely to pings. dont lose faith

    Well, I revived my router, somewhat. By shorting the pins (15-16) I was able to get it back to a state to receive a TFTP image. Can't believe it worked, but it did.

    Now, I can ping the device and it is in the right state to accept a tftp image. The power light flickers constantly and the DMZ light comes on and off every second or two. When it is in this state it seems like it is right for an image (pings and will accept tftp image any time). It seems to load any TFTP image I throw at it and finishes the tftp upload. I watch tcpdump and get no errors. Then I reboot it by pulling the power. Plug it back in and it stays as the exact same state! I can ping it and upload any tftp image again, but no change once I reboot. Anyone have any ideas?

    do you get the same result when you press the reset button. the flash is broken ,i think

    Oh my! I got the latest Linksys image to take!!! I think I was rebooting too early. This time I loaded the latest 3.03.6 image on it and did NOT reboot it. Then after a while I watched tcpdump and started getting some packets from it. IGMP packets. I browsed to the router and walaa, it's up!

    Have not had good luck with OpenWRT. Probably just me, but I'm going to try another firmware first. If I'm not happy I may come back to try this again. But this has been nothing but 2 weeks of a time bandit. Although, I really am learning how to revive a v3 router!

    Hey, I'm thinking about loadind either DD-wrt or HyperWRT. Any preference? Also, does HyperWRT have a web gui?

    I just caught this thread, cheers have one on Linksys. I had a similar experience and the Linksys firmware worked. DD-wrt or HyperWRT hmm let me think.....I think it is a personal preference. Perhaps reading about the features will help you decide. The main differences are HyperWRT is forked straight form Linksys code. DD-wrt is forked from sveasoft code. Your choice but I would suggest you educate yourselft first. I haven't tried HyperWRT but a lot of people seem happy with it. Personally I have been using sveasoft Alchemy for almost a year and am very pleased with it.

    well with me it is personal preference if you want all the features and then some go with dd-wrt.b ut if you want some feautres which are the basics go with hyperwrt. my personal saying is that more is better. but this is not always true. read the forums on dd-wrt and hyperwrt forums and see bugs or other problems do what disman_ca said educate yourselves. weigh the good and bad.

    The whole reason I bought this router was to have more options for my border router. I already own 3 of them. I don't just need the basics, but want better control over the firewall (iptables) and more options (syslog, tcpdump, ssh, etc...)

    My question is still about dd-wrt. Does it have all this stuff already compiled in? Is there anyway to add packages like OpenWRT?

    yes all this is comlied in the firmware. you could also add pakcages. but also rember that the firmware is still in pre releases and the jffs partitiion in dd-wrt is still having problems. so right now some people can add packages while other canot like me

    ok i got a bricked ver2.0 when you say connect the wire from pin 16 to the center of the left antenna.. do you mean the left antenna looking at the router from the front?? or the back?? also where can i get a pic of where pin 16 is on the chip??

    it doesent matter what ariel you conect it to, you just want somthing to ground pin 16 on, what ever one reaches best with the conducter (wire) your using.

    Hi there. I have a WRT54GS v.2
    I had ddwrt installed. After some stupid thinkink I decided to install Openwrt. Which has no web interface.. Telnet and ssh works OK but I do not know how to get back to ddwrt from telnet interface. I have read that it is possible through tftp. But I somehow cannot find out how to use it.. Is there someone that will be kind enough to let me know?
    Thank you.
