Cisco router 803 ping issue

Hi there

I have an old Cisco 803 router and I'd like to backup the IOS to a TFTP server as practise.

I am accessing the router via Hyperterminal console on a PC. A laptop, which I am going to use as the TFTP server, is connected to the e0 interface of the router.

The laptop has been assigned as static IP address of 192.168.1.65/24.  The e0 interface on the router has been assigned an IP address of 192.168.1.66/24, and they are connected via x-over cable.

Strangely, I can ping 192.168.1.66 from the laptop, but cannot ping 192.168.1.65 from the router.

Config posted below>>>

Router1#sh run
no service password-encryption
