login problems with admin/admin

[primorc1]

Hello!

I have problems with login to my router after I updated firmware. I can ping router, when I try http://192.168.1.1 it ask me for username,password and admin/admin doesn't work. I also tried root,user,administrator,password words in all combinations and nothing works. I tried last 2 firmwares
WL500gp-1.9.2.7-7g.trx and
WL500gp-1.9.2.7-8.trx

same problem with both. When I tried DD-WRT - dd-wrt.v23_asus.trx it works with no problem (root/admin). I guess I updated firmwire correctly otherwize it wouldn't even ask me for password.
Any suggestions?

regards!

ok another problem
I uploaded DD-WRT firmware which works and I changed IP from 192.168.1.1 to 10.1.1.1 . Then I tried on another computer Oleg's firmware and it changed BUT it keeped IP 10.1.1.1. So, now I can't access it with username/password (admin/admin) and I can't even rewrite it to DD-WRT because Firmware restoration program is looking for ip 192.168.1.1
Emm I red somethink about tftp command to put firmware up to specific IP, but I can't get it work. Any idea? a little help?

it works. If anyone else need help with this: this is how to do it

You need:
wl500g-clear-nvram.trx
wl500g-recover.trx
dd-wrt.v23_asus.trx

First you set router into recovery mode, then set your IP in the range of your ruter's ip (usually 192.168.1.x, gateway is 192.168.1.1). In my case I set ip 10.1.1.2 , gateway 10.1.1.1. When router in is recovery mode you should be able to ping it.

1. recovery mode
2. tftp -i 192.168.1.1 PUT wl500g-clear-nvram.trx (wait a minute)
3. recovery mode
4. tftp -i 192.168.1.1 PUT wl500g-recover.trx (wait a minute) Here I noticed that router changed IP from 10.1.1.1 to 192.168.1.1 so I had to changed my IP.
5. recovery mode
6. tftp -i 192.168.1.1 PUT dd-wrt.v23_asus.trx (wait a minute)
7. reset (power out, power in), wait a minute, login with root/admin

done. This is how to flash router without Asus firmware restoration tool. I tried to do this with Oleg's firmware but it didn't work. I guess I will stay with DD-WRT firmware until next version.

Actually, just a small bit of theory:

Oleg's fw doesn't contain any passwords. Password for web-IF is stored in nvram (username is always admin). This is true always independently from the following.

In case if there is no file /etc/passwd, telnet/ssh access is granted to user root with the same password as in web-IF. If there is file /etc/passwd then the user accounts and passwords are stored in it, which can be used for shell logins.

/etc/passwd is not stored in the firmware, but in the user-writeable area of the flash.

So, in any case the problem is in corrupted nvram or user-area-of-the-flash

BTW, have you tried reset button on the back of the router?
