|Not enough info - define your LAN - is this a hard wired connection or wireless? A household SOHO? If yes, what is your setup, direct to modem, a router, wireless router? |
Is this a company LAN? If yes, is the connection live, is the port on the switch that this connection is connected to live? Have you tested the patch cable(s). Are there lights on the NIC or the switch or router ports? Are you getting an IP address? Can you ping your gateway?
Is this a 802.11 WLAN (wireless LAN)?
Is this 3G/4G wireless?
Does a different PC/laptop connect on this connection?
Just another stupid saying...
