I have a problem at an office network.
The network has the following:
1. A Windows 2008 R2 Server running as the DHCP host
- IP address is 10.22.22.10
- DCHP range is 100 - 200
2. Unmanaged network switch
3. Modem Router
I was called in to update the password on the modem as it was changed with the internet service provider. They did not know what the log in information was for the modem and it was not the default so I reset the modem and re entered the internet service provider details.
I could connect to the internet using my laptop plugged straight into the modem router but when I plug the router into the switch and try to get to internet by plugging into the switch it does not work.
The network tries to identify and fails. The laptop reports it is an unidentified network.
Question: How can I get my laptop to access the internet when plugged into the switch?
Does the modem need to be set as a DHCP Server, DHCP Relay or disable?
Is there anything else that needs to configured in the modem?
