I have no trouble connecting to the internet with WiFi. Instead, I cannot connect with a hard-wired ethernet cable. I subscribe to Spectrum. When I go to Network, it says I am connected via USB 10/100/1000 LAN. The green light is on at the ethernet port but the orange light is not blinking. I cannot open any pages. Thanks for your help.
MacBook Air (M2, 2023)
Does it show ethernet is connected when you go to the Apple logo, system settings, network, ethernet?
MacBook Pros don't have an actual ethernet port as you already know, so you have to use an adaptor... have you verified that your adaptor is working? Does it work with other devices?
Try unplugging everything and plugging everything back in. Something may not be connected or plugged in completely.
Try restarting your Mac.

Connect to the internet with your Mac - Apple Support
I've tried everything you suggested. I assume I am connected to the internet because the green light is on for the Network and it says I am connected. Will contact Spectrum next and find out if the modem is up to date or needs to be replaced.
Usually this is due to a DNS problem.
The green light means that the connection is active, but when you try to reach, say, apple.com, you need your DNS server to convert that into the correct IP. If the DNS setting is incorrect, you cannot connect.
Go to System Settings->Network, select Ethernet, then click Details... select DNS on the left. What do you see?
What is the Ethernet cable from your adapter connecting to?
Give us all the equipment between then end of the Ethernet cable and the Spectrum coax cable. Modems, routers, switches, etc…
Note: if you are disconnecting your WiFi access device and plugging directly into the cable modem, as in only a modem, and not a router, that could be a problem.
Some ISPs lock onto the first devices MAC address (Media Access Control address, which looks like this nn:nn:nn:nn:nn:nn) it sees, and only the ISP can reset it.
Some ISPs allow power cycling the modem to latch onto a dew MAC address.
Then again, if you are plugging into a LAN Ethernet port on your router, that should work, and your router is connected to the cable modem.
Many ISPs provide a combination cable modem, router and WiFi device. It should have some LAN Ethernet ports.
And if you have a separate Ethernet switch, we want to know that as well.
I have the adapter and everything is plugged in. I unplugged the modem, plugged it back in to reset. The laptop says I am connected but I still cannot open any pages except through WiFi.
I contacted Spectrum and a gentleman came out, cleaned up all the connections on his equipment and brought internet to life on my laptop. Thanks for your help.
