cisco router 871

Hi experts, I just changed last week the configuration on my router.. but yesterday I don't know what happened...

suddenly the internet stopped working and I checked the router configuration it had the old config not the new ips I had been changed last week.

should I run some command after I change something on my router?  please I really appreciate your help, thank you!!

After changing your configuration you should replace your startup configuration for currently running configuration by issue
# wr mem
or
# copy run start

If you didn't not issue any of those commands, than restarting router restores your startup configuration before you did any changes to your router.

Also if would be a good practice to create backup of your startup configuration (or running if you want) at least to flash memory of your router (TFTP server would be better solution).
# copy start flash:
# copy run flash:

Create user with username Joe with encrypted password Smith (with privilege level 15 - all privileges)
# username Joe privilege 15 secret Smith

To delete user just use no before statement
no username Joe privilege 15 secret Smith

To check uptime for your router you can use command (when your router was last rebooted)
#sh version
somewhere around 6-th line you can find:
C871 uptime is 1 week, 3 hours, 56 minutes

Just to add on to what Predrag Jovic stated, I would recommend setting up TACACS which you could use it through Active Directory to provide additional security as it would require an account on the AD to then authenticate to your equipment. You could also stipulate permission levels (1 through 15) on what commands could and couldn't be ran on the device and by whom or a group. Also, you would be able to setup accounting which can log what commands were ran by which user to do audit trails of anyone whose in the equipment and what they potentially could be doing.
