A theory advanced on the Xfininty forums is that the DHCP Server is Releasing the IP Address before its lease period has expired, and more specifically whenever the computer goes to sleep, hibernates, or is powered down.
My computer is showing a 3-day lease period. (Windows Command > IPConfig /all)
In other words, my computer, via the router (XB6 Gateway) is assigned a dynamic IP Address from the DHCP Server for temporary use -- at least for 3 days. If I put my computer to sleep to go out for a few hours, then when I return and wake the computer from sleep, it should be using the same IP Address as before.
But what appears to be happening is that the DHCP Server (or XB6) thinks that my lease has expired, and that my computer needs a new dynamic IP Address. And that process of assigning a new IP Address is taking about 30 seconds to do.
It's as if the XB6 is ignoring renewal requests, misunderstanding the lease status, or resetting something...
So this evening I reverted from the XB6 Gateway to the older Hitron CGNM-2250 Gateway
This RESOLVED the Ethernet Connection Delay from Sleep mode. My computer now connects instantly to the internet upon wakeup (just as it did before)
Other than exchanging the Gateway, there were no other changes made at my end. Same cables, same Windows software, same Network Adapter settings..
FYI, I have 300 internet service.
I am not recommending this to everyone, as there were other tradeoffs
Download speeds stayed the same before and after the exchange: 300 Mbps
Ping time increased slightly, from 7 ms to 8 ms
Upload speed dropped dramatically from 107 Mbps down to only 16 Mbps.
I will consider going back to the XB6 (or newer XB7 when available) once the firmware issue has been resolved.
