I have been helping a friend...a 95 year old gentleman to connect his Wow computer to the Internet. He has a DSL account. The DSL modem shows a solid green power light, solid DSL light and Ethernet light occasionally blinks. BTW, the DSL modem is wired directly to the computer. When I go to the Network Settings on the computer, it shows wired connection not connected. This problem, however, is intermittent. Once when it showed there was a wired connection, there was no internet connection. I couldn't get into the modem to configure it even when the wired Ethernet showed it was connected.
I didn't find the right solution from the Internet.
