Hi, after trying to install OpenWRT I've ran into some confusions and now I cannot connect anymore to the MR3020 using LAN. After searching hours on the net I come to the conclusion that I need to shout for help.
The MR3020 ethernet LED is not going ON and I am not able to connect to the device. Also there are no IPv4 Default Gateway IP. As you can see in the picture below.

After setting up a Satic IP. I was able to set the MR3020 in Failsafe mode and Telnet to the device using Putty with the ethernet cable directly connected to the PC.

I have tried the code mount_root with no succes. And the output is:

I have tried also Firstboot also with no success. And the output is:

Hopefully someone can help me. In advance many thanks for any help on this issue.

Now reboot your mr3020, see if you can telnet into it after normal bootup.

Strange, it looks like that you have an OpenWrt indeed, but it is missing some fundamental pre-init scripts and that the jffs2 partition is not there.

If possible, try to reinstall the Attitutde Adjustment Beta 2 squashfs-factory (not jffs2 or sysupgrade) from (recommended) :
http://downloads.openwrt.org/attitude_a … actory.bin

Alternatively, you can try the less stable trunk snapshot:
http://downloads.openwrt.org/snapshots/ … actory.bin

The way to proceed is to get one of these files on your host PC and make it available to the MR3020 either by setting up an HTTP or FTP server on your PC, telnet to the MR3020 as you did, then:

# cd /tmp
# wget http://192.168.1.2/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
# sysupgrade -n openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin

or

# cd /tmp
# wget ftp://192.168.1.2/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
# sysupgrade -n openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin

Where "192.168.1.2" is your PC own IP static address. You can use the tab key to complete the long name

If everything is ok, the MR3020 should reboot automatically, and provide a telnet at 192.168.1.1, where you can change the root password and reboot to get access to the router using SSH as usual.

If you used the recommended AA beta 2 image, you should then have the LuCI admin web interface at http://192.168.1.1, where you can set up networking as you like.

Hope it helps!

EDIT: you should be able to use a single "sysupgrade" command without prior downloading the file with "wget", but this way, you are sure that you file is transfered onto the router!

Thanks for the reply johan666. I tried that several times and it doesn't connect. As I stated above the Ethernet connectivity LED on the TP-MR3020 doesn't go ON.

Then in failsafe mode,
after used "mount_root", issue command : rm -rf /overlay/etc
then reboot

wait a minute, noob question, why sysupgrade a factory image???

also, I always have seen flashing factory images with "mtd -r write blablabla firmware", what's the difference? isn't sysupgrade "complicated", and mtd more "complete" flashing (maybe better with the OP strange situation?)

Thanks

I forgot to mention. The way I'm connecting in Failsafe mode to the TP-MR3020 is directly connected with the Ethernet cable to the Laptop. Wireless on my Laptop is turned on and I'm connected to my ADSL wireless router wirelessly. Internet seems to be working when I open the browser, but when I try what you suggested in FTP and HTTP it doesn't connect and keeps trying until it gives up. See the picture below.

Is there a way to install the .bin file directly from my PC without connecting to the internet?

Start your own http server, that's it.

Yes, sysupgrade is more complicated, but it normally takes care of killing all services that would access the Flash memory and switch to ramfs, then reboots automatically once performed...

But you are right, in this particular case where everything is broken anyway, maybe "mtd -r write ... firmware" may prove to work better and has better chances to work!

So:

# cd /tmp
# wget http://192.168.1.2/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
# mtd write openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin firmware
# reboot -f

... might be more appropriate.

Or use WinSCP!! Works fine after setting the password on the OpenWrt router.

Do you have a Web server running on your PC, which is accessible even if you have a firewall on your PC (disable it temporarily, in case), and that has the downloaded firmware file in the web root directory?

Given the broken situation, I don't think it is possible to change the password, as the mtd overlay is not available, so SCP may not work.

if you have windows i suggest a simple webserver:

http://mongoose.googlecode.com/files/mongoose-3.3.exe

just place in a dir containing

http://downloads.openwrt.org/attitude_a … actory.bin

start it, eventually disable firewall on your pc and then

cd /tmp
wget http://192.168.1.2:8080/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
mtd write openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware
reboot -f

hope it helps

How can I thank you enough nebbia88. I've followed your instructions carefully and the TP-MR3020 is up and running I am able to change my passwd in Telnet and ssh into the device again. Also Ethernet LED goes ON again.
One problem I have now is to finish setting up OpenWRT. Which instruction on the net do you recommend I proceed with after this issue has happened?

Nice to know it's alive again!

You should have also luci for configuration: http://192.168.1.1

There is no universal tutorial.. Configuration depends on your needs, if you explain what do you need specifically from the router maybe we can point you in the right wiki page xD

Thanks for the link. Another issue I'm at right now is that I'm still unable to connect the MR3020 to the internet. Right now I have an ethernet cable connected directly to my ADSL wireless router. I tried e.g opkg update and this is the result:

root@OpenWrt:~# opkg update
Downloading http://downloads.openwrt.org/attitude_adjustment/12.09-beta2/ar71xx/generic/packages/Packages.gz.

 * opkg_download: Failed to download http://downloads.openwrt.org/attitude_adjustment/12.09-beta2/ar71xx/generic/packages/Packages.gz, wget returned 1.
root@OpenWrt:~#

My needs for the MR3020 are:

Connect to the internet wirelessly using a 3g/4g USB dongel
File sharing from a USB drive connected to the MR3020
A private network with chatting

In Luci this is how my LAN is setup:

Maybe here is the problem why its not connecting to the internet?

So, what is your network ?
Do you have any router other than mr3020 ?
what you connect the mr3020 to ? mr3020 connect to router ? or mr3020 just connected directly to your pc ??

According to your screenshot, you look lack of networking basic knowledge.
IP 192.168.1.2 <- your mr3020 ip
gateway 192.168.1.1 <- your router ip ? do you know what gateway is ?
dns 192.168.1.2 <- why you point dns to yourself ?

Thanks all for the help. And also thank you Johan for letting me know what Gateway is. I was able to figure out what the problem was. Not bad for someone that never had networking lessons. I was able to get Piratebox up and running. Thanks again!

Hi there,

I got the same problem as javresistance and thanks to your reply I was able to get it work ... until I tried to ping google.com

I tried two tutorials : David Darts and the one from Pabell.

My OS is Windows 7.

My Home router IP address is 192.168.2.1
My computer IP address is 192.168.2.11

My network configuration on the OpenWrt router is :

config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config interface 'lan'
option ifname 'eth0'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.2.27'
option netmask '255.255.255.0'
option gateway '192.168.2.1'
list dns '192.168.2.1'
list dns '8.8.8.8'

I also edit the firewall configuration and turn the Wifi features.

Thanks for any help you can provide
