OpenWrt Troubleshooting

Technical FAQ

I can't execute command x from the Post Installation guide, what is wrong?

First of all double check if you typed in the command correctly. If so, your box is maybe not done with installation. The first clue is, that your command line looks like this root@OpenWrt:~#. The hostname is still OpenWrt, which is changed during a successful installation.


It seems my installation is still running, what went wrong?

If your box is online for more then 45 minutes, you may take a look into it to see what is going on. When you telnet into the box, like described in the installation guide, and execute the command ps , you have a long multiple line output. If you are able to spot a line including “opkg”, then everything is fine and it just take another while to finish. You can watch the installation using the following command ( using CTRL+C to exit the command)

tail -f /var/log/messages

If you can't find opkg lines, maybe your installation is stuck in detecting the USB stick. That can happen if the USB stick does not have a proper partition table, so in the system the device appears only as /dev/sda instead of /dev/sda1. When you run tail /var/log/messages you are able to spot a loong dotted line, which means “Searching for USB”. You can verify the assumption using this command ls /dev/sd*, if you see only /dev/sda you might have an USB partition problem. The quickest solution is to change the PirateBox configuration to use the USB stick without the partition one indicate. To do so run the following commands:

sed -i 's;sda1;sda;' /etc/ext.config 
reboot & exit

After executing those line, the box will log you off and reboot. After the reboot is done, the installation tries to use /dev/sda only. See the tail commands above to watch at the installation progress. If you still have trouble, please post in the PirateBox Forum and include the output of the technical summary below.


When I connect to the PirateBox SSID, I can still access my network, but not the PirateBox.

When you just finished your PirateBox installation, and you have your network cable still plugged into your PirateBox, you can't access the PirateBox. The PirateBox 'recognizes' that your home network is active and reroutes server IPs to your wifi-client, the result is not having access to the PirateBox and Internet is working.


I can't access my PirateBox, is it bricked?

In the most cases it isn't. The first step is to try to use a normal ethernet connection (via wire) and a static IP address on the client side, which should be 192.168.1.2. That helps in some cases to get again access and do further steps. If the normal way does not help you, follow these steps to access the failsafe mode, then compare your output to "Example output for technical questions". Enter each of the commands on the linked page, note the differences, and ask for support on the PirateBox Forum or IRC channel. (If your PirateBox responds at all to these commands, there's hope!)


But all network access failed, do I have to throw it away?

If you have tried both the above steps, and asked for help on the forum, and still have an unresponsive device, you may be able to recover your device (with a little surgery) via serial access: Recover bricked TL-MR3020 Wireless N Router, an example based on the MR3020.


Why has the USB stick be FAT32? What is with that limitations?

The most OperatingSystems can handle FAT32 filesystems, which makes it the best choice for the common user. Using FAT32 limits the filesize to a maximum of 4GB. Because the USB Stick is mounted with the filetype, you can't simply change the filesystem to one of your favor. Sorry, we plan this feature for the future.


I get error messages while running opkg update

Depending on the error message several things can be wrong:

  1. Internet-Connection not correctly configured
  2. Old image used with obsolete URLs


I think I have no internet connection on my PirateBox, what am I'm doing wrong?

If you already installed PirateBox, please follow the hints about nodns. If not, it has to be figured out, which configuration is wrong. I can achieve that with running the following commands

ping -n 2 8.8.8.8
ping -n 2 google.com

If the first one failed, you have to double-check your gateway entry in /etc/config/network. If the second command fails, something is wrong with the dns entry in the already mentioned configuration file.


I want to install further software to my PirateBox, but it seems I can't connect to the internet. What is wrong?

During the first days of PirateBox we had some problems with wrong entries in network configuration. To overcome this issue, PirateBox contains a fix, which gets activated during bootup. This fix redirects all request on the box itself to the running PirateBox-Software. Assuming you did you configuration in /etc/config/network correctly, run

/etc/init.d/piratebox nodns

This command disables that fix and ping google.com should point not to 192.168.1.1 anymore.


I want to start from the beginning with flashing my device, but I don't have access to it anymore. What can I do?

You can try to reflash the device via failsafe mode and using and USB stick as data source. If you had installed an image, that does not include the USB drivers, you may try advanced solution with copying the file over the network.


I get error "No space left on device" while installing additional packages, what is wrong?

The “disk”-space of the small OpenWRT-Routers are usually very limited. The PirateBox package does a few tricks to overcome this issue. we are installing the software into something called “installation destination”. If you want to install more software on your router, you have to run the opkg command with the paramter -d <destination>.

The following is valid for PirateBox 0.6 and below:

opkg install -d piratebox <package name>

With PirateBox 1.0 we changed the destination name to a more common name

opkg install -d ext <package name>

If you still encounter this problem, you maybe already exhaustet your root diskspace (working directory for opkg) or the installation directory is really out of space (the last reason usually occur on trunk images running an “opkg upgrade”).


How can I restore the original firmware?

Restoring the original firmware to your OpenWRT device is maybe different for each device, please refer to to OpenWRT wiki for that, i.e. Restoring for MR3020. Restoring back to the stock TP-Link causes the most bricks in our forum, so do a clever consideration or ask in the forum.


It seems my Box does not accept the password when using ssh.

When using ssh on a Mac or Linux system, do not forget root@192.168.1.1 . The root@ is required, that ssh will try to login via the user “root”. If you miss that part out, the ssh command will use the user you are currently logged in. If it still does not work, try to use telnet 192.168.1.1. If that work and you already used passwd to setup a password, something went wrong while flashing. Try to reflash the device with the openwrt*.bin file, or open up a forum post for clarification.


I removed all the files from my USB stick and I'm not able to connect anymore. Is it bricked?

Don't panik. If you only removed the files on the USB Stick, the Box is using all the configuration, which was moved from the original system to the USB stick. This is the reason, why you can't connect easily anymore- the DHCP server is not working anymore. In the most situation, it could be the easiest solution to simply reflash the device. For this copy your firmware image file and a copy of you unzipped install folder, then follow this Reflash using an USB Stick-HowTo. Please plugin the USB after you successfully logged in via failsafe mode.
