Ethernet speeds vary wildly and unpredictably.
I am having trouble with wired connections to Core. I do not have any switches between the device (PC) and the router. Several times a day the download speeds drop to almost nothing and then go up to maybe 30 to 40 Mbps. Can't predict when. I have a 60Mbps provider. They were out today to check the cable and connections and found nothing wrong, and very little noise on the line. They put in a new signal amplifier as a "just in case" measure. Still have the problem.
The Core app always shows 64 Mbps download, 5.6 Mbps upload, even when the PC is running at 30 Mbps or less. Wireless devices seem to not be affected. I generally have between 9 to 12 devices active on the network, one or two wired along with an Ethernet NAS device.
My ISP has a speed test and at times I can't even load the page, let alone the test. Sometimes the test itself times out. Never experienced these problems before. Have had my Core installed for a few days and have the latest firmware installed. Have swapped in new Cat 7 flat cables.
Next step, when I get a chance, is to reinstall my prior Netgear router to see if that resolves the problem. Any other suggestions??
