Hi

I am connected to my internet with

WAN Interface

gig0/0 interface

ip add 62.x.x.x 255.255.255.252

duplex full

speed auto

LAN interface

gig0/1

ip add 10.x.x.x 255.255.255.0

duplex full

speed 100   ( i am keeping the speed 100 because it is connected in switch port f0/48,made the switch port as speed 100)

but after some time my connection to the internet goes off and i just shut and no shut the WAN interface and it comes back.

NAT is working fine.  Router is 2911

Please advice

Thanks

Hi,

Could you post your 'show log' output?

What's your WAN type or service subscribed?

Have you reported the downtime to your ISP?

Hello Majed,

Can you try to set the duplex to half instead of the full , some time it is better to set the speed/duplex to auto  and let the  two devices  negotiate speed/duplex and other physical layer  parameters.

If this did not help Please try to post your configuration here so we can help you even better.

Hope it will Help

Durga,

   I didnt get the solution for it form John. It was a problem of the modem which my ISP provided me.
