Hi,

Can you paste the router current running configuration.

DHCP is not necessary to configure,that is used to assign the IP dynamically to your desktops.

Hi,

Have you tried to configure the below lines in your router.

vpdn enable
 no vpdn logging
 vpdn-group pppoe
  request-dialin
   protocol pppoe

Can you paste the output of the below command 

#sh ip int br

Even if you are not able to access internet, contact your ISP.

regards

karuppu

Hi,

Now, configuration wise everything is ok.Better check with your ISP.

GigabitEthernet0/1         unassigned      YES unset  down                  down

I hope the cable is coming from your modem to router might be not working.befor contact with ISP check that
cable because the interface is down now.

If both your router and modem's are powered on then it should be up

Regards

Karuppu

Just have a look of my BOLD LETTERS once again

nekaratal · ‎03-04-2010

hello, so my configuration is correct? the cable to use it straight = DSL modem > cisco 3845 then cross over cable from cisco 3845 to PC right?

nekaratal · ‎03-04-2010

nekaratal · ‎03-05-2010

can i ask a question again, whats the command for the router so it will load its start up config when ever i turn it off? i keep on copyng the start up to runnn everytime i turn it off.

Reza Sharifi · ‎03-05-2010

When you are at the router save the config by issuing this command

"wr" after that your config is saved and when your reboot the router you don't loose your config any more

HTH

nekaratal · ‎03-05-2010

wont work what mean is every time i restart the router the runnng config is set on default so i have to load the start up config aain so it will be in runnin, is there any option that it will auto load the start up config every time it is turn on

KARUPPUCHAMY MALAIYANDI · ‎03-05-2010

Hi,
