Gargoyle Forum

Hi, I have a TP-Link TL-WR1043N/ND v2 running Gargoyle 1.8.1 that I bought a few months ago preloaded.

Love the ability to monitor and restrict bandwidth usage.

Finding lately that we are getting frequent disconnections from the ISP, always followed a minute or two later with a reliable reconnect. When I find the internet is not working, I check the router and it is always sitting on 0 minutes uptime.

No idea whether the router or the ISP or something else is to blame, but what diagnostics does Gargoyle provide here?

I assume there must be a log of WAN connect/disconnect, with maybe some reason for the disconnect? But can't find this in the Gargoyle interface.

If I'm going to take this up with the ISP, want to be well armed with data.

Any suggestions appreciated.

You want to do a "logread" and "dmesg" at the command line just after a disconnect to find out why.

Thanks Lantis. It just happened again, here's what I got

Does this shed any light?

Nothing out of the ordinary there. Doesn't really even show the disconnect, just the reconnect afterwards.

Thanks, that's what it looked like to me too.

Is there no way of even logging the times when a disconnect/reconnect happens, so I can hand it as a list to the ISP?

What's the timestamp format on dmesg, is it minutes/hours/days since boot?

"0 Uptime" on the router status page means your router rebooted. The cause of your reboot could be power interruption, hardware issue or software issue on your router.

A reboot is consistent with everything you reported.
