Question: Network issues
Pardon the lengthy question, but this issue is driving me nuts. I have a Time Capsule hosting our home network connected by Ethernet to a wireless modem supplied by our ISP providing 25down 2up bonded internet service (note, this issue existed with a standard modem when we had 15 over 1). We have a second Time Capsule (to extend the network), half dozen iPhones, iPads, and MacBooks connected to this WiFi network, but rarely more than one device, or two at most using the network at any given time. About once a day, most days, for an hour or less, the activity LED's on the ISP's supplied modem will show a high level of activity, yet we are not personally engaged in using any device. Indeed, when we attempt to access the internet with any device we find no available bandwidth, and I mean none. It is though something on our network is absorbing all available bandwidth. Now, if I disconnect the Ethernet connected Time Capsule that normally hosts our network and connect a device directly to the ISP's modem by WiFi then we have full bandwidth and internet connectivity back again. How could any device on our normal Time Capsule network take ALL available bandwidth? As best I can tell, none of the devices attached to our network is active when this happens, and I do not have any large files (such as photos) set to automatically back up to iCloud or the like. Even were I to have two MacBooks streaming HD video simultaneously could I deliberately replicate a situation where ALL our bandwidth was being consumed. We live in a very rural area with no close neighbors, so no chance at all that an outside source could be poaching our WiFi. I'm baffled. Could the Time Capsule (gen. 1) Ethernet connected to the ISP somehow be the issue?
