Is the LAN card disabled?
Don't know how to tell whether disabled or not. Just the day prior to sending the message for help everything was well.
Is the LAN cable connected correctly at both ends?
I am assuming you are talking about Ethernet port. There is a cable from cable modem to router and then another goes from the router to the computer and it is connected fine. There is a light on the computer where the cable hooks up and there are the following lights in the router:
Power / Status / Wan / WLan / Local Network ports 2 and 4
Also, the computer indicates "local area connection is now connected. Speed 100.0 MBPS"
Do you have a link light on the router port?
At a command (CMD) prompt, type IPCONFIG / ALL - what do you see?
There is lots of things but I will try and write what "I think" may be pertinent and if there is something else you need, let me know.
Node type: Hybrid / ip Routing Enabled: no / WINS Proxy Enabled: No
Ethernet NIC: DHCP Enabled: Yes / Autioconfig enabled: yes
Then it has IP Address / SUBNET Mask / Default Gateway /DHCP & DNS Servers, etc.
What do you need?
