#77 Router loses connection to the internet after running for some time

After some uptime and seemingly in a random fashion my router loses the connection to the internet. It seems to happen more often when I use the network more. The router is connected to the internet via a wireless connection using the onboard radio0.

When that happens, I can still access the router normally using a cable, and the connection starts working again after I restart the wireless connection or just reboot the device.

libreCMC version: libreCMC Frivolous Fred v1.4.5 r265-c7859eb6 / LuCI v1.4 branch (git-18.276.07191-c7859eb)
device: TP-Link TL-WR1043N/ND v1

I found the following stacktrace in the kernel log, which is related in time with when the connection stops working:

I do have a few more questions:

  • How long does this take to happen?
  • What kinds of devices are you connecting to the router and how many?
  • After the wireless has fallen over, is the wireless network still visible?
  • After restarting the radio, is there anything else in the kernel log?

How long does this take to happen?

Sometimes the router works fine for weeks. On some days, however, the problem occurs multiple times.

As a test, today I tried to make the problem occur by doing some http downloads with my computer that is connected via cable to the router. It took less than 10 minutes for the problem to occur.

Then, I forgot to just restart the wireless network and see the kernel log but rather rebooted the router by removing all cables and waiting a couple of seconds before reconnecting them. I continued trying to make the problem occur.

After around 35 minutes all http downloads were interrupted. Subsequently the internet connection returned to seemingly working fine. The http downloads didn't resume, however. I resumed the test by starting new downloads.

After another 11 minutes the router 'hiccuped' again, interrupting the downloads, and then returning to normal. I started again the downloads. I let the test run for an hour more without any problems and then stopped the test.

What kinds of devices are you connecting to the router and how many?

The router is wirelessly connected to another router (FRITZ!Box 6490 Cable) as a client to access the internet.

The router itself is the master of a wireless network to provide internet access to other devices. Connected to that wireless network are two Android devices, and a printer. Another computer is connected via RJ45 to the router.

After the wireless has fallen over, is the wireless network still visible?

In Luci (Network -> Wireless) the network is still enabled and displayed as connected as if everything were normal. The reception levels don't change anymore, though, and stay static.

The router cannot ping the other router

PING 192.168.178.1 (192.168.178.1): 56 data bytes

--- 192.168.178.1 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss

nor 8.8.8.8.

PING 8.8.8.8 (8.8.8.8): 56 data bytes

After restarting the radio, is there anything else in the kernel log?

The following is the full kernel log before the reboot, i.e. when the router was in the problematic state:

> How long does this take to happen? Sometimes the router works fine for weeks. On some days, however, the problem occurs multiple times. As a test, today I tried to make the problem occur by doing some http downloads with my computer that is connected via cable to the router. It took less than 10 minutes for the problem to occur. Then, I forgot to just restart the wireless network and see the kernel log but rather rebooted the router by removing all cables and waiting a couple of seconds before reconnecting them. I continued trying to make the problem occur. After around 35 minutes all http downloads were interrupted. Subsequently the internet connection returned to seemingly working fine. The http downloads didn't resume, however. I resumed the test by starting new downloads. After another 11 minutes the router 'hiccuped' again, interrupting the downloads, and then returning to normal. I started again the downloads. I let the test run for an hour more without any problems and then stopped the test. > What kinds of devices are you connecting to the router and how many? The router is wirelessly connected to another router (FRITZ!Box 6490 Cable) as a client to access the internet. The router itself is the master of a wireless network to provide internet access to other devices. Connected to that wireless network are two Android devices, and a printer. Another computer is connected via RJ45 to the router. > After the wireless has fallen over, is the wireless network still visible? In Luci (Network -> Wireless) the network is still enabled and displayed as connected as if everything were normal. The reception levels don't change anymore, though, and stay static. The router cannot ping the other router <pre>PING 192.168.178.1 (192.168.178.1): 56 data bytes --- 192.168.178.1 ping statistics --- 5 packets transmitted, 0 packets received, 100% packet loss</pre> nor 8.8.8.8. <pre>PING 8.8.8.8 (8.8.8.8): 56 data bytes --- 8.8.8.8 ping statistics --- 5 packets transmitted, 0 packets received, 100% packet loss</pre> > After restarting the radio, is there anything else in the kernel log?

The problem occurred a couple of minutes ago, again. The wireless network was shown in Luci as connected and the reception levels also updated as if everything were fine. There was no connection, anymore, though. I disabled this wireless network and enabled it again. This restored the networking. This is the kernel log after doing that:

The problem occurred a couple of minutes ago, again. The wireless network was shown in Luci as connected and the reception levels also updated as if everything were fine. There was no connection, anymore, though. I disabled this wireless network and enabled it again. This restored the networking.

Is it not a bug or should I report it somewhere else?

Or am I doing something wrong here?

I don't mean to push, I'm just not sure about how to proceed.

Did it do it again? I have yet to be able to reproduce the bug or find a change that would have caused it. I am still looking into it.

  • Does it happen with v1.4.4?
  • What WiFi chipsets are in the devices that you are using with the router?
  • Were any additional packages installed?

I flashed v1.4.4 via the factory image and I'll report back if I encounter the problem again.

I don't know the WiFi chipset of the router my router is connected to. I just know that the model is a Fritzbox 6490 Cable.

No additional packages are installed.

I've experienced this on my TL-841ND v9 running v1.4.6 as well.

The next time it happens I'll try to capture similar logs for comparison.

It might be a moot point if the device will be dropped, though (issue #94).
