new problem with TL-MR 3420

Post by rmaya »

Hi,

I've just upgraded from 1.5.2 to: gargoyle_1.5.7-ar71xx-generic-tl-mr3420-v1-squashfs-sysupgrade.bin
Now it apeared that WI-FI is not working (probably switched off and cannot be switched on by pressing QSS button)
I was trying to login to the router via browser but i don't know the password.
I was trying EVERYTHING: "admin", "password" even my old password many many times with and without capitals.
any idea how to solve this?

:?
btw there is no reaction on the RESET button and SYS light doesn't blink (just continous light)

- Remove power from router, then reconnect and start clicking fast on QSS button until SYS Led starts blinking very fast
- Set you computer IP to 192.168.1.2
- Connect your router using Telnet 192.168.1.1 with putty or whatever you use...

Execute the commands:
- mount_root
- passwd

You will be prompted for the new password in passwd command.

Still nothing,

Looks like the router is bricked... :(
Leds that are working:
- PWR
- SYS (continous light)
- 1 to 4 + WAN (depends where lan is connected)
-SYS blinks ultra fast after quick pressing QSS on startup

RES button doesnt work.

Any advice how to reinstal firmware on this? (or maybe i should get a new device?)
please mind im a noob on this subject :)

many thanks.

If SYS blinks it's not bricked. Search for "openwrt fail safe" ;)

ok all fixed now!


Edit: ok, just found out that there is no support for 3g yet.

so i've loaded polish version of gargoyle with 3g suport but (again ffs!) i cannot log on to the router... 192.168.1.1 doesnt work!
i used failsafe, used firstboot and still nothing...
when i go to telnet i can enter 192.168.1.1 and it looks like everything is connected but i cannot open this via browser :(

Привет всем !
Есть проблемка с TL-MR3420 VER.1.2
При установке последней заводской прошивки tp-link
Роутер режет скорость с 60 мб с на 30мб с
Решил поставить OPEN WRT
Первой поставил LUCI но скорость та же 30 мб и веб морда не понравилась
Поставил GARGULYA –скорость та же 30 мб но работал нормально пока не слител в ноль
Индикаторы мигают и всё.
Подключился через telnet по адресу 192.168.1.1
для активации SSH Набираем в командной строке:
/etc/init.d/dropbear start
passwd root

но программа не даёт ввести новый пароль
нажимаю на любую кнопку ноль реакции

root@(none):/# /etc/init.d/dropbear start
root@(none):/# mv: can't remove '/etc/dropbear/dropbear_dss_host_key': Read-only file system
mv: can't remove '/etc/dropbear/dropbear_rsa_host_key': Read-only file system
chown: /etc/dropbear: Read-only file system
chmod: /etc/dropbear: Read-only file system
passwd root
Changing password for root
New password:
Bad password: too weak
Retype password:
passwd: /etc/passwd: Read-only file system
passwd: can't update password file /etc/passwd
root@(none):/#
PS.ХОТЯ ЭТО НЕ ПЕРВЫЙ СЛУЧАЙ ГЛЮКА РОУТЕРА- я тогда тоже долго не мог ввести новый пароль но как то получилось и включилось SSH и я закинул прошивку в папку TEMP в роутер с помощью проги WinSCP
И прошил
