Storage Issues on OpenWrt Router

Low Space and Upgrade Problems

Sometimes your openwrt router runs out of space after updates. This is common if you keep old settings or add too many packages. Many openwrt routers have small flash memory, often less than 32MB. When you update the firmware, new files go into a special overlay partition. The overlay uses more space instead of deleting old files. Keeping old settings fills up storage even faster.

Here are some reasons you might have low space or upgrade problems:

• The router has little free space after a firmware update.

• Old settings use up important storage.

• New openwrt versions need more space, so there is less for extra packages.

• The package manager (opkg) does not check if packages work together, so upgrading many at once can cause trouble.

• Some routers, like the Asus RT-AC68U, have small NVRAM, which fills up fast and causes upgrade failures.

To avoid these problems, try these tips:

• Do a factory reset before and after updating the firmware. This clears old settings and gives you more space.

• Only upgrade packages you really need.

• Use the sysupgrade tool for firmware updates instead of updating packages one by one.

• Always back up your settings before flashing the router, in case you need them later.

The HUASIFEI 5G WiFi6 Router has more memory and storage. You can add more packages and features without running out of space as quickly.

Expanding Storage Options

If you need more space on your openwrt router, you have good choices. The HUASIFEI 5G WiFi6 Router has a USB 3.0 port. You can plug in a USB drive or hard disk to get more storage. This is great for running extra services, saving logs, or sharing files.

To add more storage, do these steps:

1. Plug a USB drive into the router’s USB 3.0 port.

2. Use the openwrt web interface (LuCI) or SSH to set up the new storage.

3. Mount the USB drive as an external root (extroot) or as a shared folder.

Tip: Always format your USB drive to a file system like ext4 before you connect it to your openwrt router.

Adding storage lets you install more packages, run file servers, or set up backups. The HUASIFEI router’s hardware supports these things, so you can enjoy your openwrt even more.

Cleaning Up Unused Files

Sometimes your openwrt router gets full of files you do not need. These can be old logs, unused packages, or big database files. Cleaning up these files gives you more space and helps your router work better.

Here is how you can clean up unused files:

• Use SSH to log into your openwrt router.

• Run the df command to see which partitions are full, especially /overlay.

• Look for big files like /etc/tertf/mac_vendor.db and delete them if you do not need them.

• Remove packages you are not using with the opkg package manager.

• Do not delete files in /tmp because this is RAM and does not free up flash storage.

• After deleting files, restart the router to make sure changes work.

Note: Only delete files if you know what they do. Deleting important files can cause problems and may need you to fix a bad flash.

If you want your openwrt router to work well, clean up unused files often.

Mounting Errors

Mounting errors can stop your openwrt router from using extra storage or starting up right. These errors often happen after a firmware update or if you change mount settings in the web interface.

Common reasons for mounting errors are:

• The router mounts the wrong device to /overlay after a firmware update.

• Automatic mounting fails, so you have to mount the overlay by hand.

• Upgrading to a new openwrt version breaks extroot setups.

• Using unsupported mount options, like ‘noacl’, can make the router lose access to important folders.

To fix mounting errors, try these steps:

• Check your mount settings in the LuCI web interface.

• If you use extroot, follow the community’s steps after updating the firmware.

• Do not add unsupported mount options.

• If a firmware update causes mounting problems, try going back to a stable version or follow community guides for help.

Warning: Wrong mount settings can make your router stop working. Always back up your settings before making changes.

The HUASIFEI 5G WiFi6 Router’s strong hardware and openwrt support make it easier to fix mounting errors. If you have trouble, you can use the USB port to flash the router or restore backups.

Network Troubleshooting in OpenWrt

Network problems can be frustrating, but you can solve most issues with a few smart steps. Your openwrt router gives you many tools for troubleshooting. You can use both the LuCI web interface and the command line (CLI) to check your router and fix problems. Let’s walk through the most common network issues and how you can fix them.

Diagnosing Connectivity

When your internet stops working, you need to find out what went wrong. Start with these steps:

1. Check if your devices connect to the router’s WiFi or LAN ports.

2. Open the LuCI web interface or use SSH to log in to your openwrt router.

3. Look at the status page to see if the WAN interface has an IP address.

4. Use the CLI to check logs. Run commands like:

   logread | grep dhcp
   logread | grep odhcpd
   logread | grep wan6
   

   These commands help you spot DHCP or IPv6 problems.

5. Make sure your firewall allows DHCP and ICMPv6 traffic. If the firewall blocks these, your devices may not get an IP address or connect to the internet.

6. Check the WAN6 interface in /etc/config/network. Make sure it asks for an IPv6 address and prefix delegation.

7. If you use IPv6, add a default route by hand if needed. Sometimes this helps restore your connection.

Tip: Always check your cables and power cycle your router before you dig into deeper troubleshooting.

WAN/LAN Settings

Your openwrt router uses WAN and LAN interfaces to separate your home network from the internet. If you set up these interfaces wrong, you may see slow speeds or no internet at all. Sometimes, default settings work fine, but other times you need to change them.

Here’s a quick look at common WAN and LAN settings:

You can see these settings in the LuCI web interface under Network > Interfaces. If you notice your WAN speed is much slower than your LAN speed, check your WAN settings and wireless drivers. Sometimes, a simple change in the configuration or updating your firmware can fix speed problems.

Note: The wireless network usually connects to the LAN. The WAN interface connects to the internet. Make sure your router settings match your network needs.

Restoring Internet Access

If your internet goes down, you can try a few steps to get it back:

1. Reboot your openwrt router. This clears memory and resets connections. Many users set up automatic reboots during the night to keep things running smoothly.

2. Check your firewall rules. Make sure NAT and FORWARD rules allow traffic from your devices to the internet.

3. If you use a proxy, set up port forwarding. Add rules to let clients reach the proxy port on your router.

4. On your devices, set the proxy to your router’s LAN IP and the correct port.

5. Test your connection by visiting a website. If it works, your settings are correct.

6. If you use a Socks5 proxy, install redsocks and set up iptables to route traffic through it. Start redsocks and check that it runs.

7. After making changes, reboot your router again to apply new settings.

Callout: If your router slows down after heavy use, a reboot often fixes the problem. This refreshes the firmware and clears up memory.

Resetting Network Configurations

Sometimes, your openwrt router gets stuck because of bad settings or a failed firmware update. If you can’t fix the problem, you may need to reset your network configuration.

Here’s how you can do it:

• Use the LuCI web interface. Go to System > Backup / Flash Firmware. Click “Perform reset” to restore default settings.

• If you use the CLI, run:

  firstboot
  reboot
  

  This wipes your custom settings and brings your router back to factory defaults.

• After the reset, log in and set up your network again. Change the default password and update your firmware if needed.

• Restore your backup if you have one. This saves time and brings back your old settings.

Warning: Resetting your router erases all custom settings. Always back up your configuration before you reset.

With these troubleshooting steps, you can solve most network problems on your openwrt router. The tools in both the web interface and CLI make it easy to check logs, change settings, and restore your internet. Keep your firmware up to date and review your router settings often for the best performance.

Preventing Future Problems

Storage Best Practices

You want your openwrt router to work well for a long time. Good habits help a lot. Pick the right filesystem before you start. Use ext4 if you plan to change or add storage later. If you put in a microSD card, make sure to expand the filesystem. This way, you get all the space for logs and apps. After adding storage, run e2fsck and resize2fs to check and grow the root partition safely.

Here are some openwrt tips for storage:

1. Do not upgrade all packages at once. Openwrt sometimes has trouble with package dependencies. Only update what you really need.

2. Always back up your router settings before big changes or updates.

3. Check your filesystem by hand sometimes. Openwrt does not always check extroot partitions for you.

4. Set your router to reboot on a schedule. This keeps it running well and clears memory.

5. Save important logs. You can keep them on a USB drive or send them to another device.

Tip: When your router works well, do not change too many settings. If you must change something, always back up first.

Reliable Network Configuration

A few smart steps can keep your openwrt router network safe and steady. Always close ports you do not use. This blocks unwanted people from getting in. Turn on NAT to hide your home network from others. Turn off ping replies so your router is harder to find.
