Internet connection dropping for 1-2 seconds 4 times an hour

nry

I have been running the same setup now for about a month without a single issue. Yesterday my internet connection on all computers on the network would drop out consistently for a matter of seconds.

For two hours I recorded times…
17:11
17:31
17:47
17:51
18:12
18:32
18:48

Seems a little coincidental that they are falling like that.

Anyway I have checked the logs and can't find anything obvious, in fact all I can find is lots of DHCP related logs (note pulled out at a different time to above recorded drop outs)

I have pfSense running inside a VM on ESXi with two virtual NICs allocated, one for WAN the other a trunk port to ESXi for my VLANs.
I have tried rebooting everything, checked the settings and still the same issue. Any ideas on what I can investigate next to stop this from happening? Getting slightly annoying!

Thanks

Also pinging googles IP you can see how it drops out here…

It would be helpful to have more information. In particular, extracts from the system log from a couple of minutes before each of the "down" times to a couple of minutes after. You can get the complete system log (rather than the most recent "n" entries) by pfSense shell command```
clog /var/log/system.log


The DHCP entries you posted are to be expected as client system renew DHCP leases. Unless there is something you haven't told us its hard to imagine how that would stop all you LAN systems accessing the Internet.

try to look out more info, like the interface went down or lost conn with some other if, and post it here! cheers!
