Wi-Fi ping spikes every 10 seconds.
Ping jumps from around 5 ms to 100 ms every 10 seconds. The issue is reproducible only when connected via Wi-Fi. When connected to the router with an Ethernet cable, the problem does not occur. R...
This is a real puzzle, that ping on a 5G WiFi connection between MacBook and RS300 shows a dramatic spike about every 10-12 seconds.
(I agree that pinging the Unify gateway eliminates any possibility that "something in the internet" is affecting this issue.)
There seem to be three possibilities:
- The MacBook
- The Gateway
- WiFi interference
The MacBook cannot connect with Ethernet and cannot connect using the 6GHz WiFi channel. (There are Thunderbolt adapters for such connections. Ethernet is inexpensive, but 6GHz WiFi is not.)
It might be interesting to force the MacBook to connect to the 2.4G channel and see if the ping spikes appear on that connection.
Is there any device available that can connect at 6GHz and also monitor ICMP?
Another experiment would be to temporarily disconnect 5G WiFi devices (one at a time) to see if perhaps one of them "does something" every 10-12 seconds that congests the network.
Macbook is connected to RS300 via 6GHZ, it does not have 6E, but it is connected via 6GHZ 160mhz
when I connect macbook to RS300 via ethernet cable(with adapter) there is no spikes at all
when I tested it - there were no other devices connected to the router
I can try to connect to 2.4/5/6 one day but can't check this now
my mistake, it even has 6E with 6GHz, but not wifi7 which should not be related to this case
Very thorough analysis. With no other devices connected to this router with WiFi (and the connection being 6GHz**), this appears to focus attention on the WiFi connection between the RS300 and the MacBook Pro. With the MacBook being portable, it might "wrap this up" if the experiment can be conducted on a different WiFi connection. (i.e. work, coffee house, friend, neighbor, etc.)
** if the problem happens with a 5GHz WiFi connection, there is always a possibility that some nearby WiFi system regularly creates network overload. Much less chance with 6GHz.
- Because 6GHz is relatively rare, and
- Because 6Ghz signal strength falls off dramatically faster than 5GHz.
