our internet is dropping out every 20, 10 or 30 min. it’s not exact but sometimes even every 5 minutes.
the connection restores usually a minute later. but i’m not able to figure out the issue.
we have 5 vlans for separate systems. each has one subnet on it. most allow traversal between each other. there is a guest network which has internet access only which is also affected.
i’ve tried setting a longer arp cache. as well i’ve checked for stp loopbacks.
there is only one dhcp server on the network, but servers with static ip’s also face the same issues.
i’m able to ping the router from my computer. im able to ping devices on the other networks. but i’m unable to ping anything outbound. i do continue to have an external ip assigned which is dynamic. it doesn’t change during the downtime.
i have not tried to ping the external ip from my computer.
