6100 Max: ISP Wan Ip Change Internet Loss - Requires Reboot

sheen73

I added that (Everything) but also just checked the others. I will see if that works.

Thanks!

sheen73

Hope you are well. This issue occurred again today.

I got into the serial console, I tried ctl+t and didn't get anything out of it. I am sure I missed a command or something. That said, I rebooted normal in the serial interface and the 6100 did not come back up, let it sit for around 20 minutes and still nothing. I unplugged the 6100 and it came back up.

These are my logs I exported - When i got into the serial console before rebooting it showed a new WAN IP address and looks like this problem starts when this occurs and it cant come back up. The logs below are reflect the old WAN IP. I

Last event when this occurred I had gateway monitoring / action disabled. This time it was not selected and still happened.

I dont use a VPN or dynamic dns if that matters.

Goto System > Routing > Gateways > Edit
and at the bottom of the page, click on "Display Advanced".

You'll find :

which means 'action' in undertaken as soon as more then 10 % is lost.
10 % lost means : 10 % of the ping packets didn't make it back. This might mean : (very) bad or overloaded WAN connection.
The action is : restart/reinit the AN connection.

If 'someone' is throwing away constantly more then 10 % of your send ping requests, then it's understandable what you see is your logs : constantly reloading of the WAN interface.

Several options :
Change the settings, for example : accept more ICMP loss.
Pick another host for dpinger to ping to.
Stop the action all together :

Try repairing your uplink (check cables inside and outside)
Get a better ISP ^^

@Gertjan
Thanks for the response - everything is new from pole to house with no splitters and good power values. (Spectrum cable). Though there are a decent amount of errors and I’m sure there are problems with isp.

This issue only occurs very infrequently, the last time was 21 days ago, with the time before that the same and it looks like it happens when isp changes wan ip.

Do you see SWAP enabled on the dashboard? That is required to store a crash report if it actually creates one.

@stephenw10

No sir, it looks like I am not? How can I enable?

Ah, interesting. OK check that a SWAP partition is defined. At the command line run: gpart list

Ok SWAP is present. Run: cat /etc/fstab

sheen73

@stephenw10
Does this mean there is nothing?

 # Device                Mountpoint      FStype  Options         Dump    Pass#

stephenw10

Oh OK, that looks correct. Try running: swapinfo

sheen73

@stephenw10


Device          512-blocks     Used    Avail Capacity

stephenw10

Hmm, odd.
Ok try changing that second line in /etc/fstab to:
/dev/nvd0p3 none swap sw 0 0

Then reboot to apply that and check swapinfo again. Or it should be shown on the dashboard.

sheen73

@stephenw10
Sorry how do i run that specifically? Below gave me permission denied error when run

/dev/nvd0p3 none swap sw 0 0

stephenw10

Sorry open /etc/fstab in Diag > Edit File from the gui.
Make that second line look like:
/dev/nvd0p3 none swap sw 0 0

sheen73

@stephenw10
Ok cool, done, working and showing on dashboard. Time to wait another 20 days to see if it fails :).

Thanks for all the help.

stephenw10

Nice! Yes if it does create a crash report you will at least see it now.

sheen73

@stephenw10
I don’t know if crash is the right wording now. Looks like on isp / wan ip change it can’t recover and gets hung.
