DD-WRT help.

[tokyoracer]

So I finally got the internet back up and running though as my router settings are now different I need to access my DD-WRT settings to my Linksys WRT54G router (that was previously being used as a wireless bridge of sorts to RJ45 computers) to get that receiving the signal. However there is an issue. It's been so long since I have confgured anything I have pretty much forgotten what I need to do to access it's settings. The website doesn't offer alot of help for me as my default I.P. for the router providing the wireless signal is already assigned to 192.168.1.1 and it's pretty crap and unreliable if I try and change that to anything else.

Any ideas how I can access the DD-WRT settings?

Hi.

Have you tried to connect directly using an ethernet cable from the pc to the ddwrt, and let dhcp assign an ip?

If you have dhcp off, maybe assign a standar ip range you would use, like 192.168.0.x or .1.x... to your pc, and ping the router.

If you don't know the ip of the router, you can try an IP Scanner, (many freeware in internet) to discover the ip of your ddwrt.

This way, if no dhcp, wondering a little you'll access the configuration webpage of the ddwrt.

Regards.

Well I tried assigning it to an IP address and well, when I try and ping it in CMD but it times out all 4 times.

I have tried a few settings but they are currently as follows:

IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Default gateway: *blank*

Preffered DNS server: 192.168.1.1
Alternate DNS server: *blank*

Hi.

So, you ¡re connected with cable to the ddwrt and leaving it to assign automatically the ip, it doesn't. So you have no ip in your pc. (Or 169.x.x.x ... it's the same... no ip assigned).

With 192.168.1.2 no ping from 192.168.1.1...

Try 192.168.0.2 and ping 192.168.0.1...

If there is no response from the ddwrt it has to have a different ip than this two, and you can do two things:

1.- use an ip scanner to know which ip it has. Trying first the range 192.168.1.x and then 192.168.0.x ...

2.- press the reset button in the rear side of the ddwrt and reset it to the factory defaults. So it will assing ip and the default options will be set.

Regards.

I tried doing all possible 192.168.0.X and 192.168.1.X from 1 to 9 and nothing but myself can be pinged. Each time the router is being pinged it times out. Any other results are from non existant IP addresses.

Have tried reseting many times before the thread without luck. Apparently the default is 192.168.1.1 (which ofourse is in use anyway but even when disconnected from the wireless and only using the RJ45 cable it still times out.

Hi.

Always to solve a problem, please use cable and not wireless.

1.- If you assign 192.168.1.2 to the pc, the ping to 192.168.1.1 times out?

2.- If you removes the ip configuration from Windows (letting it to be assigned automatically), the ddwrt gives an ip to the pc?

(You can see the ip address writing in the command prompt:

c:\> ipconfig /all

)

Regards.

I haven't touched the settings on my DD-WRT WRT54GS for years now, although I'm pretty sure the default address is 192.168.1.1 after a reset.

What does:

arp -a

give you at a command prompt when you are connected directly via a cable?

Do you have a steady power light?

What are the results from:

ipconfig /all

wireless bridge of sorts to RJ45 computers

so my question is what ip are these rj45 comps, if they get a valid ip then it should be easy to trace back, it be the gatway, so type that ip in and u should be good to change ya settings

 

[tokyoracer]

Thanks guys. Il leave it tonight and try out the suggestions tomorrow. I think javi might be onto something with that last post I hope!

 

[tokyoracer]

Well I tried ipconfig /all after allowing windows to configure it and got the IP: 0.0.0.0

When I type the arp -a command I get: "No ARP entries found".

As for the status lights, all is a-ok apart from the WLAN LED that is flashing consistantly. The port i'm connecting to (1) is fine and the power LED is steady too.

Hi.

Maybe the ddwrt isn't really reseted. ..

Let me copy and paste from Wikipedia:

Via the reset button on the router

Press and hold the button while the router is on, and keep holding it about 30 seconds. On different models you may see rapid flashing of a LED, or a red error or diagnostic LED. Wait for it to return to normal operation (typically power-LED on solid). Normal behavior here is for it to not actually clear the NVRAM. Many people think of it and phrase it that way. What it is supposed to do is return all settings to factory state. If you added new non-factory variables, they should still be there after this type of reset.Holding down the reset-button while plugging in the router achieves a different goal. Here the bootloader is in charge, so getting it to clear the memory for you may have different results. Some platforms will completely empty the NVRAM and depend on another stage of the bootloader or firmware to repopulate it. On some less-supported hardware this may have unpleasant results.

Did you do this?

It's strange the dhcp Is off. ..

Regards.

Could the router be broken? DHCP "on" is the default.

 

[tokyoracer]

Il give that a go later tonight. and No I am certain the router works absolutely fine.

Hi,
Reboot your router, make it start in failsafe mode pushing the appropriate button on the device, then connect using telnet and type firstboot. It will restore default settings.

"D_amn" I keep forgetting these are 32-bit computers using a MIPs or similar CPU with about 1MB of ram or so. It makes perfect sense to connect via a telnet port.

Excellent reminder!

Thanks guys I got it back up and running, no thanks to the crappy ISP router though.
