Relatively new SP4 (i7) connected to new Surface Dock, using the native Ethernet in the Surface Dock: After Surface Dock has been plugged in for a couple of days, wired Ethernet eventually stops functioning. "HTTP 408/409" errors when web browsing, some inane message in Edge (or Chrome) to the effect that there's "congestion on the information superhighway." Curiously enough, I can open a DOS CMD window at this time and issue successful PING commands (e.g., PING 22.214.171.124, PING GOOGLE.COM, etc.). It's just that browsing locks up.
No it's not my router or internet connection since I have several other devices that retain full internet connectivity just fine throughout all of this.
Yes I have all Surface updates.
Solution is to shut down the SP4, unplug from the Surface Dock, and power-cycle the Surface Dock (physically unplug the AC adaptor cord from the back of the Dock, wait a few seconds, then re-connect the AC power to the Surface Dock). Connect everything up again and wired Ethernet works fine... for 1-3 more days when the wired-Ethernet-failure repeats itself on the Surface Dock, requiring another power-cycle.
I'm on my 2nd Surface Dock in the past month for this same problem. The first one returned to Microsoft Store for the same problem occurring within hours instead of days so I guess there's been a progressive improvement in Microsoft's manufacturing lots.
Seems like Surface Dock desperately needs some more updating for its Ethernet firmware?
Anyone else noticed similar Surface Dock wired Ethernet problems?
