Try to connect Window 7 64 bits through Ethernet cable to my router, I had the following Error message:
WAN miniport (PPPOE) Error 651.
I had Google the problem, found a few suggestions, tried them out as list below, but still can not fix the problem.
1. Disable USB wifi driver.
2. Disable VirtualBox driver.Host only Ethernet adaptor.
3. Update Microsoft Virtual WiFi minport Adaptor #2
Thanks in advance!
It should be a driver issue. Please upgrade the Ethernet adapter driver, make sure that the driver is for Windows 7.
Here is an example:
Windows 7 - Can't connect to internet

I had update the Microsoft Virtual WiFi minport Adaptor #2 and Realtek PCIe GBE Family Controller, But I still have the same Error message as show below:
Connecting through WAN Miniport (PPPOE) ... Error 651: The modem (or other connecting device) has report an error.
p.s. I am connecting through the powerline Ethernet adapter, I have order three of them, the one connect from my TV to my router is working, only Window 7 can NOT make the connection to my router through it! I had swap the the Ethernet adaptor, but does not help.
