Configuring a 3945 Router's Gigabit Ports for internet connectivity.

RBM01991
Level 1
Level 1

Team, I would like to use gi0/2 as a way to get my internet in from my ISP. The ONT has an Ethernet port on it, that is currently connected to an HWIC-1FE card which provides me with 100 mbps. Since I'm going to upgrade to 500 mbps, and possibly Gigabit, I need to have a compatible port on this router. Can anyone provide me with some configuration steps on how to do it?

 

Here's the running config on my router at the moment. Thanks in advance!

Sure this was expected, can you post current config and old config to review?

Actually it worked, I just had to do the commands 1 by 1 and not copy and paste them all at once. Thank you both so much for all your help.
