@jgq85 said in Occasional ping timeout when pinging local network and weird issue.:
Could ping failing be at all related to a DHCP/DNS server configuration?
To dns - possible if your trying to ping via fqdn and dns failed and you would not be able to resolve what fqdn your trying to ping.
But from what you posted that seems unlikely with all of the ips failing with the same amount of losses. Seems more like you had something that the machine that was pinging had a intermittent connection problem. or you switch blipped? Something on your network caused everything your pinger was pinging to not respond. So either its connection or the really the whole network was problematic.
If it was dhcp related - its possible a client lost its lease, and had no ip, etc. But all the ips at the same time? It could of been your pinger machine? But once a lease has been gotten, its good for the time of the lease, etc. And only when it runs out would it have to renew.. Very unlikely to be related to dns or dhcp to be honest.
Did all the 5 failures for every device happen at the same time.. They all have 5 ping losses.
For being local these ping times are fairly high, 34ms - locally? That has to be wifi, and bad wifi at that.. How do you have 7ms average to google and 17,18, 34 to local IPs??
Here is ping times to my wireless harmony hub.. Which is on a different vlan that my pc ping it is on.. So its routed through pfsense, and still average of 1ms..
Ping statistics for 192.168.7.96:
Packets: Sent = 26, Received = 26, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 6ms, Average = 1ms
Control-C
Really anything locally should be like 1 or 2 ms.. Sure wireless could give you some higher than that... But average of 34 ms to something locally - there is some off there..With min being 33??
Local wired should be sub 1ms to be honest.. What your using for ping might not support showing that? There are some tools that can report sub 1ms hrping, fping for example..
Here is what typical wired pings should be locally - you can see most are sub 1ms

Seems really really odd that all your local are so high, but to 8.8.8.8 ts average of 7?
