Some month ago I had the opportunity to revamp a small lansystem, which brought me into contact with nmap, as I run linux mostly I do a lot of konsole/terminal work for fun in a way. When you don't know the IP and can't see it on the network nmap comes in handy. I generally blunder my way through some things when I am not very familiar with what I am doing. There will be a bit of that here I think.

Code: Select all

[gert@kde64byTexstar 160206-DSL-G604N-adsl]$ nmap -Pn 192.168.1.1/255

Starting Nmap 7.01 ( https://nmap.org ) at 2016-02-23 12:32 EST
Illegal netmask in "192.168.1.1/255". Assuming /32 (one host)
Nmap scan report for 192.168.1.1
Host is up (0.0040s latency).
All 1000 scanned ports on 192.168.1.1 are filtered

Nmap done: 1 IP address (1 host up) scanned in 18.87 seconds
[gert@kde64byTexstar 160206-DSL-G604N-adsl]$ 
The interesting thing is that the router was found but and the IP was the one I was using (default I think was 10.1.1.1 when it arrived some years ago). The not so good news for me is the words ..are filtered. I have googled on that and so far it seem to be a hard one to crack in simple
way.

During my search I seem to remember that I got confirmation that when doing factory reset, holding the reset for more than 15 seconds would create exactly this situation.

I have done various attempts to see if getting back to factory default is possible. I am aware of and hope that the Routertech "Repair" viewtopic.php?t=335&highlight=repair will get me further as a last ditch attempt but I am probably best off going back to windows XP. :D

Yea Xp seems to be the best OS to use when attempting to repair these old routers. Interesting to see your findings using Nmap :) .

Looks like I have better dust off an old XP pc and just use that. I do prefer to work in Linux so I am nut busting to get it done. Having lost all my wireless routers and in need of a wireless connection I remembered that I had a couple of D-Link DWL-21100AP, access points.

Not as straight forward as it looked from the manual. I did not seem to be able to connect to the box but as it had a default IP of 192.168.0.50 using 'nmap' I could again see that 'host' was there. After a stiff battle with Opera I managed to get the IP changed to 192.168.1.50, by using nmap as follows it was a relief to see that the 'host' showed up on my LAN.

Code: Select all

[gert@kde64byTexstar Desktop]$  nmap --system-dns -sn 192.168.1.1/24

Starting Nmap 7.01 ( https://nmap.org ) at 2016-02-25 22:26 EST
Nmap scan report for mygateway1.ar7 (192.168.1.1)
Host is up (0.0014s latency).
Nmap scan report for kde64byTexstar.local (192.168.1.2)
Host is up (0.00021s latency).
Nmap scan report for 192.168.1.50
Host is up (0.0029s latency).
Nmap scan report for 192.168.1.85
Host is up (0.0097s latency).
Nmap done: 256 IP addresses (4 hosts up) scanned in 12.59 seconds
[gert@kde64byTexstar Desktop]$ 
I am a big fan of Opera but to me disappointment it is getting left behind and more and more subtle problems are hitting. In this case using Opera to access the AP seems to have a problem and the webinterface does not seem to work 100%.

The problem I have just found with Opera makes me wonder if my bricked router would respond better if I use Firefox, so this will be tested next. :D

After I while I have a firmware that I can login to. I can make this either D-Link or Routertech Firmware. I now need help to restore wireless capability. Any help to do this?

More Clarification on this...

So I have used The Pc tool (the one with psp bootloader) and have uploaded and flashed the enviroment and Routertech firmware version 2.97. I can go to 192.168.1.1 with my internet browser and login with Admin and Admin.

I would now like to see if we can get Wireless working (SSID to show) as I have done with Lan.

I have observed the boot sequenced with the LED lights as follows...

POWER AND WLAN show first for about 20 seconds then WLAN turns off. At this stage I am able to login at 192.168.1.1

I am just wondering if this is correct as what should happen is power is on, status light continuously blinks and WLAN light comes on shortly after. However this is probably only correct with the D-Link firmware.

Overall I would like a suggestion on which firmware I should be using to make the wireless capability restoration easiest and as so how I would go about restoring wireless on my router.

Thanks

Thank you. I will try this.

Any suggestion on which firmware I should stick with? D-Link's or Router Tech's (preferably whichever one makes wireless recovery easier)

Our tools and tutorials work best with RouterTech firmwares.

Sucess! The Firmware tool seemed to work and restored my router's wireless operation!

Just other point I was wondering about:

>Would it be possible to configure the led's lightup during the boot sequence (Just so I know if it starts up correctly)
(i.e It used to go Power>Status(blinking)>WLAN. Now it goes Power>WLAN>WLAN off>WLAN on)

If its to hard to fix then I don't mind becuase as far as I know. Its fixed. I will also test it with making it a repetable so Ill let you know how this goes.

Kudos to TheCheif and seaeagle!

You really should read the firmware FAQ, because all these questions you are asking are fully answered there.

Hi,

I've recently acquired a D-Link G604T from a friend. It seems that the OpenWRT firmware will run on it but not support wifi. It appears that someone was able to install RouterTech on the G604T previously and it lists the G604T in the drop-down box on the RUC tool. However, running the RUC it fails with the following output:

Code: Select all

shell: no such file or directory
cm_cli_tty: no such file or directory
so it appears RUC is trying to run the command 'shell' which doesn't exist on the version of BusyBox on the G604T - it is 'ash'... so I'm guessing the cm_cli_tty command fails because RUC is unable to upload the command.

I've run the FirmwareTool and here is the output:

Code: Select all

RouterTech Firmware Tool v0.97b - by TheChief : Router check 10/23/2016 4:15:55 AM

*** WARNING! There are possible compatibility issues. This is the compatibility failure report:
  * Unknown/Unspported modem driver
  * Unknown/Unsupported core logic

Attempting to install RouterTech firmwares would probably trash your router! So do NOT do it.
But if you insist on going ahead (entirely AT YOUR OWN PERIL!), here is a further report: 
 
Select an AR7RD ADAM2 4 PORT firmware.
Latest: routertech-ar7rd-adam2-4ports-firmware-20120130.zip
Note: a later version of the firmware may exist depending on the how up to date the Firmware Tool is.
 
Please read the instructions that come with the firmware files before you upgrade.
You can use either the "Lite", or standard, or "4mb-flash" firmware images.
 
According to your current MTD values, you will NOT be able to upgrade using a single firmware image.
 
An environment restoration script has been generated for The PC-Tool/Adam2App only.
 
Your 4-port router does not seem to have a Marvell-compatible switch.
The RouterTech firmware partly supports the RTL305SC, IP175C, and (to
a lesser extent) ADM6996M switches. But there could be problems. 

Proceed at your own risk!
given the two big warnings it seems like proceeding is a BAD idea - but I'm surprised since it is clearly an AR7 based model and it is on the list. Is there anything I could do to make it work?

Thanks!

Proceeding without knowing what you are doing is indeed a BAD idea. Generally, you should not continue unless you really don't care whether the router is bricked or not. Of course it is an AR7 device, and should be compatible. However, much depends on what is currently there. The easiest way to upgrade is through the web interface of the current firmware. However, the current firmware may be set up in a way that makes it very difficult to upgrade to 3rd party firmwares from the web interface. In your current case, it sems that the MTD partitions are set up in that way. This requires some pretty techie stuff to overcome that problem. And you will need the RRT or the PCTool.

The other problem with the G604T is that there are different versions, with different hardware, but the same product name (somebody's bright idea). Unless you know exactly which version you have, it is quite possible that you will flash the wrong firmware, and hence brick the router.

In the hands of an experienced person, these are not big problems - but there is always a risk of bricking the device permanently.

My advice read the firmware FAQ and especially the de-bricking threads. Treat this situation as one in which the router is bricked, and you need to de-brick it using the RRT or the PCTool.
